Hypercontractivity for a family of quantum Ornstein-Uhlenbeck semigroups

Functional Analysis 2026-02-19 v1

Abstract

We show that a family of quantum Ornstein-Uhlenbeck semigroups is hypercontractive. We also obtain the optimal order of the optimal time up to a constant for those elements whose Gibbs state is zero. The main ingredient of our proof is Meixiner polynomials.
