On phase retrieval for continuous and discrete Fourier transforms

Roman Novikov, Tianli Xu · 2026

We continue studies on phase retrieval for continuous and discrete Fourier transforms in multidimensions. Using finite difference operators, we give a large class of unexpected examples of non-uniquen…

Melting temperature shifts from quantum fluctuations in generalized Wigner crystals

Aman Kumar, Sogoud Sherif, Veit Elser, Hitesh J. Changlani · 2026

It is generally believed that quantum fluctuations collaborate with thermal fluctuations, effectively reducing transition temperatures (e.g. for melting of charge order). We show that this is not alwa…

An O(N) quasi-Ewald splitting method for nanoconfined electrostatics

Zecheng Gan, Xuanzhao Gao, Yuqing Li · 2026

Simulating the dynamics of charged particles in quasi-two-dimensional (quasi-2D) nanoconfined systems presents a significant computational challenge due to the long-range nature of electrostatic inter…

How hard is it to verify a classical shadow?

Georgios Karaiskos, Dorian Rudolph, Johannes Jakob Meyer, Jens Eisert, Sevag Gharibian · 2025

Classical shadows are succinct classical representations of quantum states which allow one to encode a set of properties P of a quantum state rho, while only requiring measurements on logarithmically …

Non-Abelian Ginzburg-Landau Theory of Spin Triplet Superconductivity

Franklin H. Cho, Y.M. Cho, Pengming Zhang, Li-Ping Zou · 2025

We present an SU(2)xU(1) generalization of the Ginzburg-Landau theory of the spin triplet ferromagnetic superconductivity which could also describe the physics of the spin triplet magnon spintronics, …

Ergotropic advantage in a measurement-fueled quantum heat engine

Sidhant Jakhar, Ramandeep S. Johal · 2025

This paper investigates a coupled two-qubits heat engine fueled by generalized measurements of the spin components and using a single heat reservoir as sink. Our model extends the proposal of Yi and c…

Higgs Field as Architect of a Geodesically Complete Universe and Agent for New Physics in Interiors of Black Holes

Itzhak Bars · 2025

The Higgs boson is often compared to a small ripple on a vast, calm ocean. This "ocean" is the universal Higgs vacuum expectation value, about 246 GeV, permeating all space and generating particle mas…

Numerical validation of an ultracold Hubbard quantum simulator

Ben Currie, John Sturt, Evgeny Kozik · 2025

We apply the formally exact Diagrammatic Monte Carlo (DiagMC) method to probe the unprecedentedly low-temperature regime recently achieved in an ultracold-atom quantum simulation of the 2D Hubbard mod…

Spectral Energy Correlations of Gamma-Ray Bursts from Structured Jets

X. L. Zhang, Z. B. Zhang, Y. F. Huang, D. Li, X. J. Li, L. M. Song · 2025

Using 148 out-axis gamma-ray bursts, we build their spectrum-energy relations of peak energy versus isotropic energy, peak energy versus peak luminosity and peak energy versus jet-calibrated energy wh…

Emergent field theory

Erick I. Duque · 2025

The uniqueness theorems for general relativity and Yang-Mills theories can be circumvented by dropping the ubiquitous, yet often implicit, assumption that physical fields, such as the spacetime metric…

Strong converse rate for asymptotic hypothesis testing in type III

Marius Junge, Nicholas Laracuente · 2025

We extend from the hyperfinite setting to general von Neumann algebras Mosonyi and Ogawa's (2015) and Mosonyi and Hiai's (2023) results showing the operational interpretation of sandwiched relative R\…

Updated constraints on Regge-Teitelboim gravity

S. R. Pinto, C. J. A. P. Martins · 2025

In the Regge-Teitelboim model, gravity is described by embedding the space-time manifold in a (usually flat) fixed higher-dimensional background, where the embedding coordinates, rather than the metri…

Theory of Magnon Spintronics: Non-Abelian Gauge Theory of Electron Spintronics

Y.M. Cho, Franklin H. Cho · 2025

Treating the electron as a charged spinon we propose a theory of magnon spintronics, a non-Abelian gauge theory of SU(2)xU(1), which could be viewed as an effective theory of electron spintronics. Jus…

XMM-Newton follow-up of a sample of apparent low surface brightness galaxy groups detected in the ROSAT All-Sky Survey

Claudia Spinelli, Angie Veronica, Florian Pacaud, Thomas H. Reiprich, Konstantinos Migkas, Weiwei Xu, Miriam E. Ramos-Ceja · 2025

Galaxy cluster cosmology relies on complete and pure samples spanning a large range of masses and redshifts. In Xu et al. (2018) and Xu et al. (2022), we discovered an apparently new population of gal…

Excitons in fractionally-filled moir\'{e} superlattices

Junghwan Kim, Hanan Dery, Dinh Van Tuan · 2025

Long-range Coulomb forces give rise to correlated insulating states when charge particles populate a moir\'{e} superlattice at certain fractional filling factors. Such behavior is characterized by a b…
