High-temperature limit penalizing high-frequency quantum fluctuations
Graeme Pleasance, Erik Aurell, Francesco Petruccione
We revisit the Caldeira-Leggett model of quantum Brownian motion with Ohmic spectral density, and derive an additional contribution to the decoherence kernel in a new high-temperat…
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…
Decoherence from quantum spacetime noise: An open-systems framework with application to neutrino oscillations
Partha Nandi, Tiasha Bhattacharyya, A. S. Majumdar +2
We present a general open-quantum-systems framework to model decoherence induced by stochastic Planck-scale fluctuations of spacetime, focusing on the kappa-Minkowski noncommutativ…
