Trans-dimensional Hamiltonian model selection and parameter estimation from sparse, noisy data
High-throughput characterization often requires estimating parameters and model dimension from experimental data of limited quantity and quality. Such data may result in an ill-posed inverse problem, where multiple sets of parameters and model dimensions are consistent with available data. This ill-posed regime may render traditional machine learning and deterministic methods unreliable or intractable, particularly in high-dimensional, nonlinear, and mixed continuous and discrete parameter spac…

On the theory of supermodulation of the superconducting order parameter by supermodulation of the apex distance in optimally doped Bi$_2$Sr$_2$CaCu$_2$O$_{8+x}$
Recently using Scanning Josephson Tunneling Microscopy (SJTM) in the group of Séamus Davis a super-modulation of the superconducting order parameter induced by super-modulation of the distance $δ$ between planar Cu and apical O was observed in [O'Mahony et al, On the electron pairing mechanism of copper-oxide high temperature superconductivity, PNAS Vol. 119(37), e2207449119 (2022)]. The authors conclude: "concurrence of prediction from strong correlation theory... with these observations ind…

Measurements of the absolute branching fractions of the doubly Cabibbo-suppressed decays $D^+\to K^+π^0$, $D^+\to K^+η$ and $D^+\to K^+η^{\prime}$
Using $20.3\,\rm fb^{-1}$ of $e^+e^-$ collision data collected at a center-of-mass energy of 3.773\,GeV with the BESIII detector, we present improved measurements of the absolute branching fractions of the doubly Cabibbo-suppressed decays $D^+\to K^+π^0$, $D^+\to K^+η$ and $ D^+ \to K^+ η^{\prime}$ with the double-tag method. The statistical significance of each signal decay exceeds $10σ$. The branching fractions are determined to be ${\mathcal B}(D^+\to K^+ π^0) = (1.45 \pm 0.06 \pm 0.06)…

Superconductivity in the spin-state crossover materials: Nickelates with planar-coordinated low-spin Ni$^{2 }$ ions

Superconductivity in the spin-state crossover materials: Nickelates with planar-coordinated low-spin Ni$^{2+}$ ions
We theoretically study quasi-two-dimensional nickel compounds, where the nickel ions assume Ni$^{2+}$ $d^8$ valence state and feature a low-spin $S=0$ ground state quasidegenerate with $S=1$ ionic excitations. Such a level structure is supported by square-planar coordination of nickel ions or a suitable substitution of apical oxygens. We construct the corresponding singlet-triplet exchange model and explore its phase diagram and excitation spectrum. By hole doping, we further introduce mobile N…

Calamus 36 Earth! my likeness!
Woah! This poem is such a strong statement of queer love I want to jump right to it
an athlete is enamoured of me—and I of him.
But toward him there is something fierce and terrible in me, eligible to burst forth,
I dare not tell it in words—not even in these songs.
A same-sex love, bursting, terrible. A secret he must keep even from his poems. My heart aches for his suppressed passion.
I don't want to overlook the rest of the poem: Whitman compares his love for the athlete to the Earth. The Earth which also has something terrible ready to break forth. It's really quite grandiose and apocalyptic.
(The Live Oak draft is worth comparing because it's even more direct. "an athlete loves me, and I him").

Our planet is currently reverberating from the impact of a powerful coronal mass ejection (CME) that struck Earth head-on in the early hours of June 1 — and the resulting auroras were absolutely stunning.
The CME erupted during an M8.2 class solar flare eruption on May 30 at 8:05 p.m. EDT (00:05 GMT on May 31) and has been racing toward Earth at nearly 1,938 km/s or 4.3 million mph.
When it slammed into Earth's magnetic field, the impact triggered a severe (G4) geomagnetic sto…

Götz #Kubitschek spricht in Worthülsen. Das ist ebenso wenig auszuhalten - und auch lächerlich - wie die Worthülsen gestrig Linker.
Sie werden wohl durch leere, aber ideologisch Aufgeladene Worthülsen zusammengehalten.
Intellektueller ist Kubitshek sicherlich keiner. Er ist ein Kleinkrämer recher Agitation und Bannerredner von Faschismus.

Ich spreche aus einer Position der absoluten Ignoranz, aber ich tippe, die Trumpdiktatur ist so, wie sich bis vor ein paar Jahren schlechte französische Komiker eine amerikanische Diktatur vorgestellt hätten.
