sympy2c: from symbolic expressions to fast C/C++ functions and ODE solvers in Python
Uwe Schmitt, Beatrice Moser, Christiane S. Lorenz +1
Computer algebra systems play an important role in science as they facilitate the development of new theoretical models. The resulting symbolic equations are often implemented in a…
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…
c-number Quantum Generalised Langevin Equation for an open system
L. Kantorovich, H. Ness, L. Stella +1
We derive a number Generalised Langevin Equation (GLE) describing the evolution of the expectation values of the atomic position operators…
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…
The Generalized Langevin Equation: An efficient approach to non-equilibrium molecular dynamics of open systems
L. Stella, C. D. Lorenz, L. Kantorovich
The Generalized Langevin Equation (GLE) has been recently suggested to simulate the time evolution of classical solid and molecular systems when considering general non-equilibrium…
