Correlations, information backflow, and objectivity in a class of pure dephasing models
Nina Megier, Andrea Smirne, Steve Campbell +1
We critically examine the role that correlations established between a system and fragments of its environment play in characterising the ensuing dynamics. We employ a class of dep…
Deep Learning for Principal-Agent Mean Field Games
Steven Campbell, Yichao Chen, Arvind Shrivats +1
Here, we develop a deep learning algorithm for solving Principal-Agent (PA) mean field games with market-clearing conditions -- a class of problems that have thus far not been stud…
Quantum Darwinism in a composite system: Objectivity versus classicality
Barış Çakmak, Özgür E. Müstecaplıoğlu, Mauro Paternostro +2
We investigate the implications of quantum Darwinism in a composite quantum system with interacting constituents exhibiting a decoherence-free subspace. We consider a two-qubit sys…
Collision models in open system dynamics: A versatile tool for deeper insights?
Steve Campbell, Bassano Vacchini
Understanding and simulating how a quantum system interacts and exchanges information or energy with its surroundings is a ubiquitous problem, one which must be carefully addressed…
Fast and robust magnon transport in a spin chain
Anthony Kiely, Steve Campbell
A protocol for fast and robust magnon transport in a one-dimensional spin chain is devised. Employing an approximate mapping between the chain and a single harmonically trapped par…
Work statistics and symmetry breaking in an excited state quantum phase transition
Zakaria Mzaouali, Ricardo Puebla, John Goold +2
We examine how the presence of an excited state quantum phase transition manifests in the dynamics of a many-body system subject to a sudden quench. Focusing on the Lipkin-Meshkov-…
