Entropy production and information fluctuations along quantum trajectories [PDF]
, 2013 Employing the stochastic wave function method, we study quantum features of stochastic entropy production in nonequilibrium processes of open systems. It is demonstarted that continuous measurements on the environment introduce an additional, non-thermal

Modelling intermittent anomalous diffusion with switching fractional Brownian motion
New Journal of Physics, 2023 The stochastic trajectories of molecules in living cells, as well as the dynamics in many other complex systems, often exhibit memory in their path over long periods of time.

Linear quantum state diffusion for non-Markovian open quantum systems
, 1996 We demonstrate the relevance of complex Gaussian stochastic processes to the stochastic state vector description of non-Markovian open quantum systems. These processes express the general Feynman-Vernon path integral propagator for open quantum systems ...

Frequency-domain computation of quadratic-exponential cost functionals for linear quantum stochastic systems [PDF]
IFAC-PapersOnLine, 2019 This paper is concerned with quadratic-exponential functionals (QEFs) as risk-sensitive performance criteria for linear quantum stochastic systems driven by multichannel bosonic fields.

Quantum stochastic integrals under standing hypotheses
Journal of Mathematical Analysis and Applications, 1987 We study the meaning of stochastic integrals when the integrator is a quantum stochastic process which is not quite a martingale, in that it obeys estimates of the type advocated by \textit{E. J. McShane} [Stochastic calculus and stochastic models. (1974; Zbl 0292.60090)] in the classical case.

Ramsey interferometry of non-Hermitian quantum impurities
Physical Review Research, 2020 We introduce a Ramsey pulse scheme which extracts the non-Hermitian Hamiltonian associated with an arbitrary Lindblad dynamics. We propose a related protocol to measure via interferometry a generalized Loschmidt echo of a generic state evolving in time ...

Series of iterated quantum stochastic integrals [PDF]
, 2000 We consider series of iterated non-commutative stochastic integrals of scalar operators on the boson Fock space. We give a sufficient condition for these series to converge and to define a reasonable operator. An application of this criterion gives a condition for the convergence of some formal series of generalized integrator processes such as ...

A Galerkin FEM for Riesz space-fractional CNLS
Advances in Difference Equations, 2019 In quantum physics, fractional Schrödinger equation is of particular interest in the research of particles on stochastic fields modeled by the Lévy processes, which was derived by extending the Feynman path integral over the Brownian paths to a path ...
