We consider the application of the original Meyer-Miller (MM) Hamiltonian to mapping fermionic quantum dynamics to classical equations of motion. Non-interacting fermionic and bosonic systems share the same one-body density dynamics when evolving from the same initial many-body state. The MM classical mapping is exact for non-interacting bosons, and therefore, it yields the exact time-dependent one-body density for non-interacting fermions as well. Starting from this observation, the MM mapping… Expand

A complete quasiclassical map for the dynamics of interacting fermions.
TLDR
The proposed classical map becomes complete under the evolution of quadratic Hamiltonians and is extended for all even order observables and provides an accurate description of the dynamics for an interacting quantum impurity model in the coulomb blockade regime, at both low and high temperatures. Expand
Generalized spin mapping for quantum-classical dynamics.
TLDR
A spin-mapping approach based on the well-known quantum equivalence between a two-level system and a spin-1/2 particle is generalized to describe the dynamics of N-level systems and derives a simple way to approximate correlation functions in complex nonadiabatic molecular systems via classical trajectories. Expand
Spin-mapping approach for nonadiabatic molecular dynamics.
TLDR
A trajectory-based method for simulating nonadiabatic dynamics in molecular systems with two coupled electronic states and the results are seen to be a significant improvement compared to both standard Ehrenfest dynamics and linearized semiclassical MMST mapping, without adding any computational complexity.

Application of a semiclassical model for the second-quantized many-electron Hamiltonian to nonequilibrium quantum transport: the resonant level model.
TLDR
Comparisons with exact results generated for the resonant level model reveal that a semiclassical treatment of transport provides a quantitative description of the dynamics at all relevant timescales for a wide range of bias and gate potentials, and for different temperatures. Expand
Classical mapping for Hubbard operators: application to the double-Anderson model.
TLDR
A classical Cartesian mapping for Hubbard operators is developed to describe the nonequilibrium transport of an open quantum system with many electrons and captures all transport channels involving transition between many electron states. Expand
A Cartesian quasi-classical model to nonequilibrium quantum transport: the Anderson impurity model.
TLDR
The recently proposed quasi-classical approach for a second quantized many-electron Hamiltonian in Cartesian coordinates is applied, showing that the current mapping is capable of capturing quantitatively the Coulomb blockade effect and the temperature dependence of the current below and above the blockade.

Trotter-based simulation of quantum-classical dynamics.
TLDR
An algorithm for simulating the quantum-classical Liouville equation, which describes the dynamics of a quantum subsystem coupled to a classical bath, is presented in this paper and is shown to reproduce the exact results for stronger nonadiabatic coupling and much longer times using fewer trajectories than other schemes.

Mixed quantum-classical dynamics
Mixed quantum-classical equations of motion are derived for a quantum subsystem of light (mass m) particles coupled to a classical bath of massive (mass M) particles. The equation of motion followsExpand
A classical analog for electronic degrees of freedom in nonadiabatic collision processes
It is shown how a formally exact classical analog can be defined for a finite dimensional (in Hilbert space) quantum mechanical system. This approach is then used to obtain a classical model for theExpand
Quantum-Classical Nonadiabatic Dynamics: Coupled- vs Independent-Trajectory Methods.
TLDR
This paper presents a simple quantum-classical scheme based on coupled classical trajectories and test it against the full quantum mechanical solution from wave packet dynamics for some model situations which represent particularly challenging problems for the above-mentioned traditional methods.
