Nodal algebraic curves and entropy diagnostics in degenerate two-dimensional harmonic-oscillator shells

C A Escobar Ruiz, H Olivares-Pilon, A M Escobar-Ruiz ยท 2026

Degenerate quantum eigenspaces can support substantial changes in nodal geometry at fixed energy. We show that, for the two-dimensional isotropic harmonic oscillator, this restructuring is organized bโ€ฆ

Geodesically Complete Curvature-Bounce Inflation

Damien A. Easson ยท 2026

The early universe need not be described by an incomplete inflationary phase connected to a separate, more exotic prehistory. Recent results show that, within non-static FRW cosmology, only positive sโ€ฆ

Perturbative Coulomb branches on $\mathbb{R}^3\times S^1$: the global D-term potential

Arash Arabi Ardehali, Daniel J. Resnick ยท 2026

We find the perturbative potential on the 3d $\mathcal{N}\!=\!2$ Coulomb branch arising from a chiral 4d $\mathcal{N}\!=\!1$ gauge theory on $\mathbb{R}^3 \times S^1$, zeta-regularizing the D-term couโ€ฆ

Emergence of $\pi$ from Equatorial Quantum Localization

Bin Ye, Ruitao Chen, Lei Yin ยท 2026

We present a genuinely non-radial quantum-mechanical route by which $\pi$ emerges from equatorial localization on the sphere. For the highest-weight branch of spherical harmonics, this localization isโ€ฆ

Neural and Tensor Networks in the Study of Quantum Annealing Processors

Tomasz Smierzchalski ยท 2026

Quantum annealing targets low-energy solutions of Ising/QUBO problems, but reliable assessment requires more than best-energy comparisons. This dissertation develops a benchmarking framework for D-Wavโ€ฆ

Nature and nurture: the dynamical ages of in situ and accreted globular clusters in the Milky Way

Eugenio Carretta (INAF - Osservatorio di Astrofisica e Scienza dello Spazio di Bologna) ยท 2026

The bifurcated age-metallicity relation of globular clusters (GCs) in the Milky Way (MW) shows that GCs are either originated in situ or accreted into the Galaxy from former satellites of the MW. The โ€ฆ

A Speculative Benchmark for the AMS-02 Electron and Positron Spectra from a Time-Symmetric Transport Hypothesis

Yi Yang ยท 2026

We revisit the time-symmetric interpretation of antiparticles and explore whether it can be connected, as a speculative benchmark, to the distinct spectral structures observed in the AMS-02 electron aโ€ฆ

Thermodynamic Phase Transitions in Einstein-Maxwell-Scalar-Gauss-Bonnet Gravity

Cristian Erices, Stella Kiorpelidi ยท 2026

Although asymptotically flat black holes generically lack thermodynamic phase transitions, we show that curvature-induced scalarization of electrically charged black holes in Einstein-Maxwell- Scalar-โ€ฆ
