OQuPy: A Python package to efficiently simulate non-Markovian open quantum systems with process tensors
Gerald E. Fux, Piper Fowler-Wright, Joel Beckles +11
Non-Markovian dynamics arising from the strong coupling of a system to a structured environment is essential in many applications of quantum mechanics and emerging technologies. De…
A numerical approach for calculating exact non-adiabatic terms in quantum dynamics
Ewen D C Lawrence, Sebastian F J Schmid, Ieva Čepaitė +2
Understanding how non-adiabatic terms affect quantum dynamics is fundamental to improving various protocols for quantum technologies. We present a novel approach to computing the A…
Liouville Space Neural Network Representation of Density Matrices
Simon Kothe, Peter Kirton
Neural network quantum states as ansatz wavefunctions have shown a lot of promise for finding the ground state of spin models. Recently, work has been focused on extending this ide…
Determining the validity of cumulant expansions for central spin models
Piper Fowler-Wright, Kristín B. Arnardóttir, Peter Kirton +2
For a model with many-to-one connectivity it is widely expected that mean-field theory captures the exact many-particle limit, and that higher-order cumulant expansion…
A quantum model of lasing without inversion
Nicholas Werren, Erik Gauger, Peter Kirton
Starting from a quantum description of multiple Lambda-type 3-level atoms driven with a coherent microwave field and incoherent optical pumping, we derive a microscopic model of la…
Exact dynamics of non-additive environments in non-Markovian open quantum systems
Dominic Gribben, Dominic M. Rouse, Jake Iles-Smith +6
When a quantum system couples strongly to multiple baths then it is generally no longer possible to describe the resulting system dynamics by simply adding the individual effects o…
