Hankel operators between different doubling Fock spaces
Journal of Inequalities and Applications, 2022 In this paper, we study Hankel operators on the doubling Fock spaces for all possible 1 ≤ p , q < ∞ $1\leq p ...

Topological transitivity of translation operators in a non-separable Hilbert space
Karpatsʹkì Matematičnì Publìkacìï, 2023 We consider a Hilbert space of entire analytic functions on a non-separable Hilbert space, associated with a non-separable Fock space. We show that under some conditions operators, like the differentiation operators and translation operators, are ...

Dynamics of strongly interacting systems: From Fock-space fragmentation to many-body localization [PDF]
Physical review B, 2019 We study the $t\text{\ensuremath{-}}V$ disordered spinless fermionic chain in the strong-coupling regime, $t/V\ensuremath{\rightarrow}0$. Strong interactions highly hinder the dynamics of the model, fragmenting its Hilbert space into exponentially many ...

General Criterion for Non-Hermitian Skin Effects and Application: Fock Space Skin Effects in Many-Body Systems. [PDF]
Physical Review LettersNon-Hermiticity enables macroscopic accumulation of bulk states, named non-Hermitian skin effects. The non-Hermitian skin effects are well established for single-particle systems, but their proper characterization for general systems is elusive. Here, we

Interacting Fock space versus full Fock module [PDF]
, 2008 We present several examples where moments of creators and annihilators on an {\it interacting Fock space} may be realized as moments of creators and annihilators on a {\it full Fock module}.

How to differentiate a quantum stochastic cocycle. [PDF]
, 2010 Two new approaches to the infinitesimal characterisation of quantum stochastic cocycles are reviewed. The first concerns mapping cocycles on an operator space and demonstrates the role of H\"older continuity; the second concerns contraction operator ...

Many-body localization in Fock space: A local perspective [PDF]
Physical review B, 2018 A canonical model for many-body localization (MBL) is studied, of interacting spinless fermions on a lattice with uncorrelated quenched site-disorder. The model maps onto a tight-binding model on a `Fock-space (FS) lattice' of many-body states, with an ...

Asymptotic States and S-Matrix Operator in de Sitter Ambient Space Formalism
Universe, 2023 Within the de Sitter ambient space framework, the two different bases of the one-particle Hilbert space of the de Sitter group algebra are presented for the scalar case.
