Localized Fock space cages in kinetically constrained models
Physical review BWe investigate a mechanism for non-ergodic behavior in many-body quantum systems arising from destructive interference, leading to localization in Fock space.

A class of weighted composition operators on the Fock space
Complex Variables and Elliptic Equations, 2019By applying reproducing kernel techniques, a class of weighted composition operators on the Fock space, which are unitarily equivalent to nonzero constant multiple of composition operators, are characterized completely.

HANKEL MEASURES FOR FOCK SPACE
Bulletin of the Australian Mathematical Society, 2022AbstractInspired by Xiao’s work on Hankel measures for Hardy and Bergman spaces [‘Pseudo-Carleson measures for weighted Bergman spaces’. Michigan Math. J.47 (2000), 447–452], we introduce Hankel measures for Fock space $F^p_\alpha $ . Given $p\ge 1$ , we obtain several equivalent descriptions for such measures on $F^p_\alpha $ .

Unbounded Weighted Composition Operators on Fock space
Potential Analysis, 2018In this paper, we consider unbounded weighted composition operators acting on Fock space, and investigate some important properties of these operators, such as C $\mathcal {C}$ -selfadjoint (with respect to weighted composition conjugations), Hermitian ...

Low-Energy Fock-Space Localization for Attractive Hard-Core Particles in Disorder
, 2017We study a one-dimensional quantum system with an arbitrary number of hard-core particles on the lattice, which are subject to a deterministic attractive interaction as well as a random potential.

FRACTIONAL FOCK–SOBOLEV SPACES
Nagoya Mathematical Journal, 2018Let $s\in \mathbb{R}$ and $0<p\leqslant \infty$. The fractional Fock–Sobolev spaces $F_{\mathscr{R}}^{s,p}$ are introduced through the fractional radial derivatives $\mathscr{R}^{s/2}$. We describe explicitly the reproducing kernels for the fractional Fock–Sobolev spaces $F_{\mathscr{R}}^{s,2}$ and then get the pointwise size estimate of the ...

Linear Operators on Fock Spaces
Integral Equations and Operator Theory, 2017The aim of this paper is to extend several results about properties of some linear operators on the Fock space \(F_\alpha^2\) to linear operators on Fock spaces \(F_\alpha^p\) for ...

The preceding chapters dealt with the non-commutative analogues of discrete r.v.’s, then of real valued r.v.’s, and we now begin to discuss stochastic processes. We start with the description of Fock space (symmetric and antisymmetric) as it is usually given in physics books.

We describe a Monte-Carlo algorithm to solve exactly the ground-state problem for a system of up to four nucleons interacting via a scalar neutral meson field. The mesonic degrees of freedom are treated exactly without recourse to the potential approximation.
