Domain-wall melting in all-to-all QSSEP from random-matrix theory

Denis Bernard, Lorenzo Piroli, Stefano Scopa · 2026

We study the melting of a domain wall in the quantum simple exclusion process with all-to-all hoppings (a.k.a. the charged SYK$_2$ model). We show that the real-time dynamics of physical quantities of…

Characterizations of amorphic association schemes in terms of fusing triples

Yanzhen Xiong · 2026

Let $\mathcal{R}$ be an association scheme with nontrivial relations $A_1,\ldots,A_d$. We call $\mathcal{R}$ amorphic if every possible fusion of its nontrivial relations gives rise to a fusion scheme…

The maximum size of the partial ground set of skew Bollob\'{a}s systems

Yu Fang, Tao Feng, Xiaomiao Wang · 2026

A skew Bollob\'{a}s system $\mathcal{P}=\{(A_i,B_i):1\leq i\leq m\}$ is a collection of pairs of disjoint subsets of $[n]$ such that $A_i\cap B_j\ne\emptyset$ for any $1\leq i<j\leq m$. Denote by $S_1…

Unmasking Hidden Wigner's Symmetry from First Principles

Phong Dang, Daniel Langr, Tomas Dytrych, Jerry P. Draayer, David Kekejian · 2026

We present quantitative evidence that high-quality internucleon forces derived from $\chi$EFT exhibit a striking dominance of Wigner's supermultiplet symmetry, without invoking the large-$N_c$ limit o…

When all parallel sets of a $ C^1 $-hypersurface are nowhere $ C^1 $-regular

Mario Santilli · 2026

We prove a necessary and sufficient condition for a $ C^1 $-hypersurface to have all parallel sets nowhere $ C^1 $-regular. As a corollary, we deduce that for a generic $ C^1 $-regular convex body all…

All pure entangled states can lead to fully nonlocal correlations

Martin J. Renner, Edwin Peter Lobo, Arturo Konderak, Remigiusz Augusiak, Antonio Acin · 2026

It is a well-established fact that some quantum correlations can be nonlocal, meaning that they cannot be described by a local hidden variable model. Certain quantum correlations have a form of nonloc…

Multimodal LLMs are not all you need for Pediatric Speech Language Pathology

Darren Furst, Sebastian Steindl, Ulrich Schafer · 2026

Speech Sound Disorders (SSD) affect roughly five percent of children, yet speech-language pathologists face severe staffing shortages and unmanageable caseloads. We test a hierarchical approach to SSD…
