Operator growth and Krylov construction in dissipative open quantum systems [PDF]
Journal of High Energy Physics, 2022 Inspired by the universal operator growth hypothesis, we extend the formalism of Krylov construction in dissipative open quantum systems connected to a Markovian bath.

Dissipative Operators on Quotient Spaces of H2 [PDF]
Journal of Mathematical Analysis and Applications, 1993 For an inner function \(\varphi\) on the unit disc \(D\), let \(A(\varphi)\) denote the commutant of the compression of the standard unilateral shift onto \(H^ 2/ \varphi H^ 2\). In this paper the author finds necessary and sufficient conditions for an operator in \(A(\varphi)\) to be dissipative.

Multidimensional stochastic dissipative quantum dynamics using a Lindblad operator [PDF]
, 2022 International audienceIn this paper, multidimensional dissipative quantum dynamics is studied within a system–bath approach in the Markovian regime using a model Lindblad operator. We report on the implementation of a Monte Carlo wave packet algorithm in

Dissipative Schrödinger-type operator as a model for generation and recombination [PDF]
, 2002 Non-selfadjoint operators play an important role in the modeling of open quantum systems. We consider a one-dimensional Schroedinger-type operator with dissipative boundary conditions and dissipative delta potentials.

Is the linearized Boltzmann-Enskog operator dissipative? [PDF]
, 2001 In this paper, it is shown that the linearized Boltzmann-Enskog collision operator cannot be dissipative in the L2-space setting contrarily to the linearized Boltzmann operator.

Dissipative Schrödinger–Poisson systems [PDF]
, 2004 We deal with a stationary, dissipative Schrödinger–Poisson system which allows for a current flow through an open, spatially one-dimensional quantum system determined by a dissipative Schrödinger operator.

Operator-splitting schemes for degenerate, non-local, conservative-dissipative systems [PDF]
, 2022 In this paper, we develop a natural operator-splitting variational scheme for a general class of non-local, degenerate conservative-dissipative evolutionary equations.

Karpatsʹkì Matematičnì Publìkacìï, 2013 A general form of a maximal dissipative subspace extension (in particularly of an operator extension) of a finite-dimensional nondensely defined restriction of a symmetric operator with arbitrary defect numbers is established.

SciPost Physics, 2020 We generalize the theory of flow equations to open quantum systems focusing on Lindblad master equations. We introduce and discuss three different generators of the flow that transform a linear non-Hermitian operator into a diagonal one. We first test

Bi-Variationality, Symmetries and Approximate Solutions
Современная математика: Фундаментальные направления, 2021 By a bi-variational system we mean any system of equations generated by two different Hamiltonian actions. A connection between their variational symmetries is established. The effective use of the nonclassical Hamiltonian actions for the construction of
