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…
