We have developed a thermodynamic theory in the non-equilibrium regime, which we
describe as a thermodynamic system–bath model [Koyanagi and Tanimura, J. Chem. Phys …

We revisit the mathematics of exactly solvable Unruh-DeWitt detector models, interacting
with massless scalar fields under instantaneous interactions, to construct a relativistic …

The dynamical Casimir effect is the physical phenomenon where the mechanical energy of a
movable wall of a cavity confining a quantum field can be converted into quanta of the field …

We develop a thermodynamic theory in the non-equilibrium regime by extending a theory
based on the dimensionless (DL) minimum work principle previously developed for a …

We present a quantum heat engine based on a quantum Otto cycle, whose working
substance reproduces the same outcomes of a SU (1, 1) interference process at the end of …

We formulate a thermodynamic theory applicable to both classical and quantum systems.
These systems are depicted as thermodynamic system–bath models capable of handling …

Quantum heat engines (QHEs) are established by applying the principles of quantum
thermodynamics to small− scale systems, which leverage quantum effects to gain certain …

We realize the mechanical dynamical Casimir effect (DCE) in a hybrid optomechanical
system consisting of a cavity mode, a low-frequency mechanical oscillator, and a two-level …

In science and technology, precision measurement of physical quantities is crucial, and the
quantum Fisher information (QFI) plays a significant role in the study of quantum systems. In …

Platforms based on transmission lines are nowadays employed for the simulation of
standard phenomena in quantum electrodynamics and quantum field theory. In this work, we …
