A nonabelian Wilson surface on a lattice

Andreas Gustavsson · 2026

We analyze the nonabelian surface holonomy on a bipartite hypercubic lattice following a proposal in arXiv:1002.4636 [hep-th]. The bipartite structure of the lattice enables us to introduce spike stri…

Continuum-marginal optimal transport: a mesh-free kernel method

Yumiharu Nakano · 2026

In this paper we study continuum-marginal optimal transport. Given a time-continuous family of probability marginals, the problem is to recover the minimum-energy velocity field whose flow reproduces …

Natural-orbital locking reveals hidden steady-state skin order in Gaussian open fermion chains

Y. T. Wang, X. Z. Zhang · 2026

Nonreciprocal relaxation matrices can have skin-localized right eigenmodes, but their imprint on a mixed steady state is not fixed by the density profile alone. We develop an exact steady-state theory…
