Borel -multitransforms and Quantum Leray-Hirsch: integral representations of solutions of quantum differential equations for -bundles

Giordano Cotti

In this paper, we address the integration problem of the isomonodromic system of quantum differential equations (s) associated with the quantum cohomology of -bun…

Dynamical quantum phase transitions from random matrix theory

David Pérez-García, Leonardo Santilli, Miguel Tierz

We uncover a novel dynamical quantum phase transition, using random matrix theory and its associated notion of planar limit. We study it for the isotropic XY Heisenberg spin chain.…

Impediments to diffusion in quantum graphs: geometry-based upper bounds on the spectral gap

Gregory Berkolaiko, James B. Kennedy, Pavel Kurasov +1

We derive several upper bounds on the spectral gap of the Laplacian with standard or Dirichlet vertex conditions on compact metric graphs. In particular, we obtain estimates based…

Families of non-tiling domains satisfying Pólya's conjecture

Pedro Freitas, Isabel Salavessa

We show the existence of classes of non-tiling domains satisfying Pólya's conjecture in any dimension, in both the Euclidean and non-Euclidean cases. This is a consequence of a mor…
