Multiscale Violation of Onsager Reciprocity: Thermomechanical Proof, Atomic Evidence, and Graphene Predictions

Monty Dabas · 2026

Onsager reciprocity $L_{ij}=L_{ji}$ is a cornerstone of near-equilibrium thermodynamics derived from microscopic time-reversal symmetry. We develop a geometric framework in which entropy-weighted repa…

The quantum smooth label cover problem is undecidable

Eric Culf, Kieran Mastel, Connor Paddock, Taro Spirig · 2025

We show that the quantum smooth label cover problem is undecidable and RE-hard. This sharply contrasts the quantum unique label cover problem, which can be decided efficiently by a result of Kempe, Re…

Rapidity-Dependent Spin Decomposition of the Nucleon

Florian Hechenberger, Kiminad A. Mamo, Ismail Zahed · 2025

We show that the two-dimensional Fourier transform of the generalized parton distributions (GPDs) has two distinct interpretations: at zero skewness ($\eta=0$) it yields the familiar impact-parameter …

Generalized Neumann's Principle as a Unified Framework for Fractional Quantum and Conventional Ferroelectricity

Hongsheng Pang, Lixin He · 2025

Monolayer In$_2$Se$3$ exhibits unexpected in-plane polarization, despite having $C_{3v}$ symmetry, a feature that was traditionally considered forbidden by symmetry. To explain this remarkable behavio…

Succinct Perfect Zero-knowledge for MIP*

Honghao Fu, Kieran Mastel, Xingjian Zhang · 2025

In their recent breakthrough result, Slofstra and the second author show that there is a two-player one-round perfect zero-knowledge MIP* protocol for RE (STOC'24). We build on their result to show th…

Converse bounds for quantum hypothesis exclusion: A divergence-radius approach

Kaiyuan Ji, Hemant K. Mishra, Milan Mosonyi, Mark M. Wilde · 2025

Hypothesis exclusion is an information-theoretic task in which an experimenter aims at ruling out a false hypothesis from a finite set of known candidates, and an error occurs if and only if the hypot…
