On nefness of the lowest piece of Hodge modules
We give degree lower bounds for quotient line bundles of the lowest piece of a Hodge module induced by a variation of Hodge structures outside a simple normal crossing divisor. We also give sufficient conditions on when the lowest piece is nef. Classical results say when X is a curve or monodromies are unipotent, the lowest piece is a nef vector bundle on X. In dimension greater than or equal to two, if the monodromies at infinity are not unipotent there are counter-examples where nefness fails…

Axion Superradiance in Dipole Magnetic Fields of Pulsars
We consider constraints on the axion-photon coupling by superradiance due to a plasma instability in the magnetospheres of millisecond pulsars. We compute the growth rate of a superradiant axion cloud in a dipole magnetic field, and give a semi-analytical formula for the superradiance rate for the lowest state. By requiring the associated instability time to be longer than the characteristic age of the supermassive black-widow millisecond pulsar PSR J0952-0607, we examine the pulsar-timing arra…

Gravitational Wave Propagation in a Geometric Condensate in Starobinsky Cosmology
In this paper we propose a new paradigm for cosmology: a time dependent scalar condensate background originated from the quadratic $(R + αR^2)$ Starobinski model, where $R$ is the Ricci scalar and $α$ the coupling constant. In weak gravity limit the system decouples into a conventional graviton and a higher derivative scalar. It was shown earlier through works from our group, \cite{ssg,sg,us}, that the latter can sustain an oscillatory lowest energy configuration or a {\it{Geometric Condensat…

On the behavior of the ground state energy under weak perturbation of critical quasilinear operators in $\mathbb{R}^N$
We consider a critical quasilinear operator $-Δ_p u +V|u|^{p-2}u$ in $\mathbb{R}^N$ perturbed by a weakly coupled potential. For $N>p$, we find the leading asymptotic of the lowest eigenvalue of such an operator in the weak coupling limit separately for $N>p^2$ and $N\leq p^2$.

The lowest-energy state inside each permutation symmetry sector $h$, arising in the $P$-fold tensor product decomposition, is well approximated by a U$(N)$ coherent (quasi-classical, variational) state, specially in the limit $P\…

Noether's theorem connects symmetries to invariants in continuous systems, however its extension to discrete systems has remained elusive.

A detailed application is given to electromagnetism, where energy-momentum conservation laws are rapidly obtained in highly generalized for…

All-Optical Azimuthal Trapping of Dissipative Kerr Multi-Solitons for Relative Noise Suppression
Temporal cavity solitons, or dissipative Kerr solitons (DKS) in integrated microresonators, are essential for deployable metrology technologies. Such applications favor the lowest noise state, typically the single-DKS state where one soliton is in the resonator. Other multi-DKS states can also be reached, offering better conversion efficiency and thermal stability, potentially simplifying DKS-based technologies. Yet they exhibit more noise due to relative soliton jitter, and are usually not com…

Numerical analysis of the convex relaxation of the barrier parameter functional of self-concordant barriers
Self-concordant barriers are essential for interior-point algorithms in conic programming. To speed up the convergence it is of interest to find a barrier with the lowest possible parameter for a given cone. The barrier parameter is a non-convex function on the set of self-concordant barriers on a given cone, and finding an optimal barrier amounts to solving a non-convex infinite-dimensional optimization problem. In this work we study the degradation of the optimal value of the problem when the…

For unitary groups associated to a ramified quadratic extension of a $p$-adic field, we define various regular formal moduli spaces of $p$-divisible groups with parahoric levels, characterize exceptional special divisors on them, and construct correspondences between them. We formulate arithmetic transfer conjectures, which are variants of the arithmetic fundamental lemma conjecture in this context. We prove the conjectures in the lowest dimensional cases.

The chiral limit in which analytic Landau level-like single-particle states form an ``ideal" Chern band and local interactions lead to Laughlin-like FCIs at $1/3$ filling, has been very useful for understanding these systems by relating them to the lowest Landau level. We show, however, that, even in the idealized chiral limit, a fluctuating …

EV Charging Cost by the Numbers.
I charge my car at home almost nightly wirh a Level 2 Flo 30A/240V charger.
I noticed today that they have added an "estimated rate" for my address based on my utility (BC Hydro) charge so that it can estimate the cost of the charging.
Their estimate is $0.11400/kWh. I drive alot. 160km a day when I am commuting to work and then 50-100km in the evening 4-5 days a week Dashing. Thanks to dashing I have a solid record of odometer readings.
We have both tiered and time of day pricing so it's complicated to do this manually. I do most of my charging during the lowest rate overnight. I have the Flo charger set to only charge at full 30A power between 11PM and 7AM to match the overnight rate, then 15A in "off peak" (standard rate) and to turn off completely during on-peak 4PM to 9PM times.
I think their estimate is quite accurate considering the overnight rate is usually $0.14 - $0.05/kWh. Ill include my latest electrical bill. (we are billed monthly)
Here are the numbers.
A "full tank" of battery is 65kWh
Monthly: eg. March (full time commuting plus dashing) 4668km
30 charging sessions
853.4kWh
$97 ($2.07/100km)
Last 12 months: 56,107km
8793kWh
$1,002 ($1.78/100km)
There are a few free charges at work in there (15 in the year?) but any saving is eaten up by $6/day parking cost.
As a comparison if I drove our 2014 Prius C hybrid 56,000km at its general fuel mileage of 5L/100km and an average price of $1.60/L that would be $2,800. So I am saving by more than half, and probably more than that, compared to one of the best mileage hybrids out there.
It makes less and less sense to buy a gas car.

At each time step, the resulting saddle point system becomes nearly singular in the locking regime, where the solid is nearly incompressible. This near-singularity stems from the leading block, which corresponds to a linear elasticity system. To enable efficient iterative…

Active View Selector: Fast and Accurate Active View Selection with Cross Reference Image Quality Assessment
We tackle active view selection in novel view synthesis and 3D reconstruction. Existing methods like FisheRF and ActiveNeRF select the next best view by minimizing uncertainty or maximizing information gain in 3D, but they require specialized designs for different 3D representations and involve complex modelling in 3D space. Instead, we reframe this as a 2D image quality assessment (IQA) task, selecting views where current renderings have the lowest quality. Since ground-truth images for candid…

Creation of a degenerate Bose-Bose mixture of erbium and lithium atoms
We report the realization of a degenerate mixture of $^{166}$Er and $^{7}$Li atoms in their lowest spin state. The two species are sequentially laser-cooled and loaded into an optical dipole trap, then transported to a glass cell in which further cooling to degeneracy occurs. Since Er is more weakly trapped, it serves as a coolant for Li, and we observe efficient sympathetic cooling facilitated by a large interspecies elastic scattering cross section. Three-body losses are found to be small at …

Asymmetry of curl eigenfields solving Woltjer's variational problem
We construct families of rotationally symmetric toroidal domains in $\mathbb R^3$ for which the eigenfields associated to the first (positive) Ampèrian curl eigenvalue are symmetric, and others for which no first eigenfield is symmetric. This implies, in particular, that minimizers of the celebrated Woltjer's variational principle do not need to inherit the rotational symmetry of the domain. This disproves the folk wisdom that the eigenfields corresponding to the lowest curl eigenvalue must be…

Updated determination of light-cone distribution amplitudes of octet baryons in lattice QCD

The analysis is carried out on a large number of $n_f=2+1$ lattice gauge ensembles, including ensembles at physical pion (and kaon) masses. These are spread across five different lattice spacings, enabling a controlled continuum limit. The main differences with respect to our earlier work are the use of two-loop conversion fac…

The mechanism of tornadogenesis from the perspective of vortex tubes
In this paper, we propose a new theory on tornadogenesis from the perspective of vortex tubes based on Kelvin-Helmholtz Theorems. When the pressure difference between the lowest pressure line from the wall cloud down to the ground and its surroundings is large enough, the increase of vorticity inside the squeezed vortex tube can reach the tornado level, and thus a tornado is born. When the pressure difference increases, the tornado strength increases. When the pressure difference decreases, the…

Rational Motions of Minimal Quaternionic Degree with Prescribed Line Trajectories
In this paper, we study how to find rational motions that move a line along a given rational ruled surface. Our goal is to find motions with the lowest possible degree using dual quaternions. While similar problems for point trajectories are well known, the case of line trajectories is more complicated and has not been studied. We explain when such motions exist and how to compute them. Our method gives explicit formulas for constructing these motions and shows that, in many cases, the solution…

We experimentally demonstrate cavity-free feedback cooling of the three lowest-lying collective modes of a Bose-Einstein condensate in a prolate harmonic trap. Using shadowgraph imaging as an \textit{in situ} probe of the atomic density, we measure the time-dependent centers-of-mass and widths of the condensate in two dimensions and use these measurements to damp oscillations in the two visible dipole modes and the low-frequency quadrupole mode. By inducing oscillations in the condensate, we sh…

We present a generic platform for designing topological flat bands through applying an artificially designed electrostatic superlattice potential to a thin film with Rashba spin-orbit coupling. Utilizing many-body exact diagonalization, we show that the lowest flat band can host fractional Chern insulator states at filling factor $n = 1/3$ and $2/3$. Notably, these fractional charge states present robustly in a broad regime of the parameter space. We further discuss the potential realistic mate…

Building on the idea that lack of experience is a source of errors but that experience should reduce them, we model agents' behavior using a stochastic choice model (logit quantal response), leaving endogenous the accuracy of their choices. In some games, higher accuracy leads to unstable logit-response dynamics. Starting from the lowest possible accuracy, we define the barrier to learning as the maximum accuracy which keeps the logit-response dynamic stable (for all lower accuracies). This def…

We theoretically investigate the impact of the anomalous magnetic moment (AMM) of Dirac fermions on the fermionic Casimir effect under magnetic fields. We formulate it as an extension of the well-known Lifshitz formula. From our formula, we find that the AMM increases the fermionic Casimir energy. In particular, when the AMM is large enough, the Casimir energy is significantly enhanced by the gapless behavior of the lowest Landau level. We also quantitatively estimate the Casimir energy from el…

Eternal inflation near inflection points: a challenge to primordial black hole models
Inflation with an inflection point potential is a popular model for producing primordial black holes. The potential near the inflection point is approximately flat, with a local maximum next to a local minimum, prone to eternal inflation. We show that a sufficient condition for eternal inflation is $λ_1 \leq 3$, where $λ_1$ is the index of the `exponential tail,' the lowest eigenvalue of the Fokker--Planck equation over a bounded region. We write $λ_1$ in terms of the model parameters for li…

Density-functional-theory calculations locate the lowest-energy Pr superlattices for both Ba- and Y-site substitution. In the Ba-site case, the smaller Pr ion pulls the surrounding atoms inward. This breathing-mode distortion pins charge-stripe walls to the Pr columns and forces them to align along the $c$ axis. Y-site Pr is larger than the host i…
