Accelerated calculation of impurity Green's functions exploiting the extreme Mpemba effect
David J. Strachan, Archak Purkayastha, Stephen R. Clark
Simulating the dynamics of quantum impurity models remains a fundamental challenge due to the complex memory effects that arise from system-environment interactions. Of particular…
Extracting Dynamical Maps of Non-Markovian Open Quantum Systems
David J. Strachan, Archak Purkayastha, Stephen R. Clark
The most general description of quantum evolution up to a time is a completely positive tracing preserving map known as a dynamical map . Here we consider …
Schwinger-Keldysh non-perturbative field theory of open quantum systems beyond the Markovian regime: Application to spin-boson and spin-chain-boson models
Felipe Reyes-Osorio, Federico Garcia-Gaitan, David J. Strachan +3
We develop a unified framework for open quantum systems composed of many mutually interacting quantum spins, or any isomorphic systems like qubits and qudits, surrounded by one or…
Specialising Neural-network Quantum States for the Bose Hubbard Model
Michael Y. Pei, Stephen R. Clark
Projected variational wavefunctions such as the Gutzwiller, many-body correlator and Jastrow ansatzes have provided crucial insight into the nature of superfluid-Mott insulator tra…
Entropy production in the mesoscopic-leads formulation of quantum thermodynamics
Artur M. Lacerda, Michael J. Kewming, Marlon Brenes +4
Understanding the entropy production of systems strongly coupled to thermal baths is a core problem of both quantum thermodynamics and mesoscopic physics. While there exist many te…
