Impossibility of Refrigeration and Engine Operation in Minimal Qubit Repeated-Interaction Models
Gabrielle Barsky-Giles, Alessandro Prositto, Matthew Gerry +1
We investigate the operation of a qubit as a quantum thermal device within the repeated interaction framework, allowing for strong system-bath coupling and finite interaction times…
Collisional model with dissipative and dephasing baths: Nonadditive effects at strong coupling
Alessandro Prositto, Carlos Ramon-Escandell, Dvira Segal
The repeated interaction model provides a framework for emulating and analyzing the dynamics of open quantum systems. We explore here the dynamics generated by this protocol in a s…
Thermal state preparation by repeated interactions at and beyond the Lindblad limit
Carlos Ramon-Escandell, Alessandro Prositto, Dvira Segal
We study the nature of thermalization dynamics and the associated preparation (simulation) time under the repeated interaction protocol uncovering a generic anomalous, Mpemba-like…
Equilibrium and nonequilibrium steady states with the repeated interaction protocol: Relaxation dynamics and energetic cost
Alessandro Prositto, Madeline Forbes, Dvira Segal
We study the dynamics of a qubit system interacting with thermalized bath-ancilla spins via a repeated interaction scheme. Considering generic initial conditions for the system and…
