Stochastic collisional quantum thermometry
Eoin O'Connor, Bassano Vacchini, Steve Campbell
We extend collisional quantum thermometry schemes to allow for stochasticity in the waiting time between successive collisions. We establish that introducing randomness through a s…
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…
Counterdiabatic control in the impulse regime
Eoin Carolan, Anthony Kiely, Steve Campbell
Coherent control of complex many-body systems is critical to the development of useful quantum devices. Fast perfect state transfer can be exactly achieved through additional count…
Diverging quantum speed limits: a herald of classicality
Pablo M. Poggi, Steve Campbell, Sebastian Deffner
When is the quantum speed limit (QSL) really quantum? While vanishing QSL times often indicate emergent classical behavior, it is still not entirely understood what precise aspects…
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-…
