Driving Spin-Boson Models From Equilibrium Using Exact Quantum Dynamics
G. M. G. McCaul, C. D. Lorenz, L. Kantorovich
We present an application of the Extended Stochastic Liouville Equation (ESLE) Phys. Rev. B 95, 125124, which gives an exact solution for the reduced density matrix of an open syst…
Modelling a Bistable System Strongly Coupled to a Debye Bath: A Quasiclassical Approach Based on the Generalised Langevin Equation
L. Stella, H. Ness, C. D. Lorenz +1
Bistable systems present two degenerate metastable configurations separated by an energy barrier. Thermal or quantum fluctuations can promote the transition between the configurati…
Partition-free approach to open quantum systems in harmonic environments: an exact stochastic Liouville equation
G. M. G. McCaul, C. D. Lorenz, L. Kantorovich
We present a partition-free approach to the evolution of density matrices for open quantum systems coupled to a harmonic environment. The influence functional formalism combined wi…
Nonequilibrium processes from Generalised Langevin Equations: realistic nanoscale systems connected to two thermal baths
H. Ness, A. Genina, L. Stella +2
We extend the Generalised Langevin Equation (GLE) method [Phys. Rev. B 89, 134303 (2014)] to model a central classical region connected to two realistic thermal baths at two differ…
Applications of the Generalised Langevin Equation: towards a realistic description of the baths
H. Ness, L. Stella, C. D. Lorenz +1
The Generalised Langevin Equation (GLE) method, as developed in Ref. [Phys. Rev. B 89, 134303 (2014)], is used to calculate the dissipative dynamics of systems described at the ato…
