- Abstract: We develop the categorical context for defining Hermitian non-semisimple
TQFTs. We prove that relative Hermitian modular categories give rise to
modified Hermitian WRT-TQFTs and provide numerous examples of these structures
coming from the representation theory of quantum groups and quantum
superalgebras. The Hermitian theory developed here for the modified Turaev-Viro
TQFT is applied to define new pseudo-Hermitian topological phases that can be
considered as non-semisimple analogs of Levin-Wen models.

with pseudofermions [51.52945471576731]
This work presents gauge-equivariant architectures for flow-based sampling in fermionic lattice field theories using pseudofermions as estimators for the fermionic determinant.
This is the default approach in state-of-the-art lattice field theory calculations, making this development critical to the practical application of flow models to theories such as QCD.

Generalized uncertainty principles (GUP) and, independently, Lorentz symmetry violations are two common features in many candidate theories of quantum gravity.
A large class of both isotropic and anisotropic GUP models is shown to produce signals experimentally indistinguishable from those predicted by the Standard Model Extension.
In particular, bounds on isotropic GUP models are improved by a factor of $107$ compared to current spectroscopic bounds and anisotropic models are constrained for the first time.

models [50.92854230325576]
Kitaev spin models are well known for being exactly solvable in a certain parameter regime via a mapping to free fermions.
We use classical simulations to explore a novel variational ansatz that takes advantage of this fermionic representation.
We also comment on the implications of our results for simulating non-Abelian anyons on quantum computers.
