Journal ArticleDOI
Operational dynamic modeling transcending quantum and classical mechanics.
TL;DR: In this paper, the authors introduce a general and systematic theoretical framework for operational dynamic modeling (ODM) by combining a kinematic description of a model with the evolution of the dynamical average values.
Journal ArticleDOI
Accurate Lindblad-form master equation for weakly damped quantum systems across all regimes

TL;DR: In this paper, the authors derive a Lindblad-form master equation for weakly-damped systems that is accurate for all regimes, including thermal damping, and show that when this master equation breaks down, so do all time independent Markovian equations, including the B-R equation.
Journal ArticleDOI
Koopman wavefunctions and classical-quantum correlation dynamics
TL;DR: This paper addresses the long-standing problem of formulating a dynamical theory of classical–quantum coupling using the exactly solvable model of a degenerate two-level quantum system coupled to a classical harmonic oscillator.
Journal ArticleDOI
Wigner phase-space distribution as a wave function
TL;DR: In this article, the Wigner function of a pure quantum state is shown to be a wave function in a specially tuned Dirac bra-ket formalism, and the probability amplitude for the quantum particle to be at a certain point of the classical phase space.
Journal ArticleDOI
Efficient method to generate time evolution of the Wigner function for open quantum systems
TL;DR: In this article, the authors presented an efficient fast Fourier method for evolving the Wigner function that has a complexity of $O(NlogN)$ where N is the size of the array storing the function.
