Bipartite and tripartite entanglement in pure dephasing relativistic spin-boson model
Kensuke Gallock-Yoshimura, Erickson Tjoa
We study nonperturbatively the entanglement generation between two and three emitters in an exactly solvable relativistic variant of the spin-boson model, equivalent to the time-in…
Exact treatment of the memory kernel under time-dependent system-environment coupling via a train of delta distributions
Yuta Uenaga, Kensuke Gallock-Yoshimura, Takano Taira
Memory effects in a quantum system coupled to an environment are one of the central features in the theory of open quantum systems. The dynamics of such quantum systems are typical…
Relativistic quantum Otto heat engine using a three-level Unruh-DeWitt detector
Tomoya Hirotani, Kensuke Gallock-Yoshimura
In this study, we explore a relativistic quantum Otto heat engine with a qutrit as the working substance interacting with a quantum scalar field in curved spacetime. Unlike qubits,…
