Energy momentum tensor correlators in $ϕ^4$ theory II: The spin-two sector
We extend the computation of the C_T charge of the 2-point function of the Energy-Momentum Tensor to 4-loops. We show that C_T decomposes into two sectors, the conformal sector, which encodes the value of the central charge at fixed points and an RG-sector that contains logarithmic and constant corrections proportional to the beta-function. This latter constitutes the main new result of this work and is inaccessible via CFT methods alone. Furthermore, we demonstrate that C_T satisfies an eigenv…

Fine-Tuning ASR for Stuttered Speech: Personalized vs. Generalized Approaches
Stuttering -- characterized by involuntary disfluencies such as blocks, prolongations, and repetitions -- is often misinterpreted by automatic speech recognition (ASR) systems, resulting in elevated word error rates and making voice-driven technologies inaccessible to people who stutter. The variability of disfluencies across speakers and contexts further complicates ASR training, compounded by limited annotated stuttered speech data. In this paper, we investigate fine-tuning ASRs for stuttered…

Near-Optimal Nonconvex-Strongly-Convex Bilevel Optimization with Fully First-Order Oracles
In this work, we consider bilevel optimization when the lower-level problem is strongly convex. Recent works show that with a Hessian-vector product (HVP) oracle, one can provably find an $ε$-stationary point within ${\mathcal{O}}(ε^{-2})$ oracle calls. However, the HVP oracle may be inaccessible or expensive in practice. Kwon et al. (ICML 2023) addressed this issue by proposing a first-order method that can achieve the same goal at a slower rate of $\tilde{\mathcal{O}}(ε^{-3})$. In this pap…

Existence Theorem for Cumulative Universe Towers and Its Applications
This paper builds a cumulative tower of Grothendieck universes that provides a precise size discipline for higher type theory. Starting from an increasing sequence of inaccessible cardinals, we give an inductive-recursive definition of universe codes, their decoding functor, and a rank that controls the growth of each code. For every level of the tower we prove closure under dependent products, dependent sums, identity types, and all finite limits and colimits; the colimit part is obtained with…

Excitation and tunneling spectra of a fractional quantum Hall system in the thin cylinder limit
The excitations of fractional quantum Hall effect (FQHE) states have been largely inaccessible to experimental probes until recently. New electron scanning tunneling microscopy (STM) results from Hu et.al. (2023) show promise in detecting and identifying these excited states via the local density of states (LDOS) spectrum. On a torus, there exists a mapping to a 1D lattice Hamiltonian with center-of-mass or dipole moment conservation. In this work, we apply perturbation theory starting from the…

Implementation and Basis Construction for Smooth Finite Element Spaces
The construction of $C^m$ conforming finite elements on simplicial meshes has recently advanced through the groundbreaking work of Hu, Lin, and Wu (Found. Comput. Math. 24, 2024). Their framework characterizes smoothness via moments of normal derivatives over subsimplices, leading to explicit degrees of freedom and unisolvence, unifying earlier constructions. However, the absence of explicit basis functions has left these spaces largely inaccessible for practical computation. In parallel, multi…

Here, we introduce subwavelength phase engineering inside crystalline silicon, offering a novel strategy for integrated photonics. We design and numerically demonstrate a volumetric metaoptic monolithically embedded within the bulk, achieving full 2$π$ phase control at telecommunication wav…

In this work we show that as little as 40 kg of 60%-enriched uranium can be used to build a crude nuclear weapon with a kiloton yield. While too large to fit on a missile, such a weapon could be delivered by shipping container. This analysis is motivated by the June 2025 Israeli and US attacks on Iran, especially the bombings of the nuclear facilities at Natanz, Fordow, and Isfahan. The Iranian stockpile of approximately 408 kg of 60%-enriched uranium is, at the time of writing, inaccessible to…

Yup, the hard part isn’t writing code.
I’m always a bit cautious of the argument that the barriers are a good thing. That easily slips into harmful gatekeeping if we aren’t careful. It’s not good when programming is inaccessible or unwelcoming.
What •is• good is that writing code slows you down and (if you’re good) makes you •think• about what the heck you’re doing — the work @… is talking about — with a depth and detail that no amount of chin-stroking and up-front design work can match. Skipping that work, however you skip it, is a false gain.

Direct correlation of line intensity mapping and CMB lensing from lightcone evolution
Line intensity mapping (LIM) promises to probe previously inaccessible corners of the faint and high-redshift universe. However, confusion with bright foregrounds is a major challenge for current-era pathfinder LIM experiments. Cross-correlation with cosmic microwave background (CMB) lensing is a promising avenue to enable the first LIM detections at high redshifts, a pristine probe of fundamental physics but sparsely populated by faint galaxies, and to further probe the connection between matt…

Dynamical decoupling of interacting spins through group factorization
Dynamical decoupling (DD) is a well-known open-loop protocol for suppressing unwanted interactions in a quantum system, thereby drastically extending the coherence time of useful quantum states. In the original framework of evolution symmetrization, a DD sequence was shown to enforce a symmetry on the unwanted Hamiltonian, thereby suppressing it if the symmetry was inaccessible. In this work, we show how symmetries already present in the undesired Hamiltonian can be harnessed to reduce the comp…

Time-hidden magnetic order in a multi-orbital Mott insulator
Photo-excited quantum materials can be driven into thermally inaccessible metastable states that exhibit structural, charge, spin, topological and superconducting orders. Metastable states typically emerge on timescales set by the intrinsic electronic and phononic energy scales, ranging from femtoseconds to picoseconds, and can persist for weeks. Therefore, studies have primarily focused on ultrafast or quasi-static limits, leaving the intermediate time window less explored. Here we reveal a me…

Open materials systems are often inaccessible to conventional atomistic simulations, which add and remove atoms by creating high-energy defects that may be sampled with vanishing probability. This longstanding challenge motivates a new Hamiltonian Monte Carlo method that maps the grand canonical problem to a canonical system involving non-interacting fictitious particles. To trial deletions or insertions, a real or fictitious particle is selected according to an energy-based biasing scheme and …

A Strongly Non-Saturated Aronszajn Tree Without Weak Kurepa Trees
For an inaccessible cardinal $κ$, there exists a forcing poset which is Y-proper and $κ$-c.c., collapses $κ$ to become $ω_2$, and adds an Aronszajn tree together with a family of $ω_2$-many strongly almost disjoint subtrees of it. The quotients of this forcing in intermediate extensions are indestructibly Y-proper on a stationary set with respect to any Y-proper forcing extension. As a consequence of this forcing, we prove from an inaccessible cardinal that the existence of a strongly non-…
