Periodically refreshed baths to simulate open quantum many-body dynamics
Archak Purkayastha, Giacomo Guarnieri, Steve Campbell +2
Obtaining dynamics of an interacting quantum many-body system connected to multiple baths initially at different, finite, temperatures and chemical potentials is a challenging prob…
Quantum Darwinism in a structured spin environment
Eoghan Ryan, Mauro Paternostro, Steve Campbell
We examine the emergence and suppression of signatures of quantum Darwinism when the system of interest interacts with a complex, structured environment. We introduce an extended s…
Action quantum speed limits
Eoin O'Connor, Giacomo Guarnieri, Steve Campbell
We introduce action quantum speed limits (QSLs) as a family of bounds on the minimal time to connect two states that, unlike the usual geometric approach, crucially depend on how t…
Kibble-Zurek scaling in quantum speed limits for shortcuts to adiabaticity
Ricardo Puebla, Sebastian Deffner, Steve Campbell
Geometric quantum speed limits quantify the trade-off between the rate with which quantum states can change and the resources that are expended during the evolution. Counterdiabati…
In situ thermometry of a cold Fermi gas via dephasing impurities
Mark T. Mitchison, Thomàs Fogarty, Giacomo Guarnieri +3
The precise measurement of low temperatures is a challenging, important and fundamental task for quantum science. In particular, in-situ thermometry is highly desirable for cold at…
Non-equilibrium steady-states of memoryless quantum collision models
Giacomo Guarnieri, Daniele Morrone, Barış Çakmak +2
We investigate the steady state properties arising from the open system dynamics described by a memoryless (Markovian) quantum collision model, corresponding to a master equation i…
