Lecture notes on classical and quantum non-Markovianity
Graeme Pleasance
The study of non-Markovian quantum processes has attracted significant interest in recent decades, giving rise to several competing notions of quantum non-Markovianity. These notes…
Non-Markovianity in collision models with initial intra-environment correlations
Graeme Pleasance, Angel E. Neira, Marco Merkli +1
Collision models (CMs) describe an open system interacting in sequence with elements of an environment, termed ancillas. They have been established as a useful tool for analyzing n…
Pseudomode description of general open quantum system dynamics: non-perturbative master equation for the spin-boson model
Graeme Pleasance, Francesco Petruccione
We outline a non-perturbative approach for simulating the behavior of open quantum systems interacting with a bosonic environment defined by a generalized spectral density function…
Generalized theory of pseudomodes for exact descriptions of non-Markovian quantum processes
Graeme Pleasance, Barry M. Garraway, Francesco Petruccione
We develop an exact framework to describe the non-Markovian dynamics of an open quantum system interacting with an environment modeled by a generalized spectral density function. T…
