Black holes have presented us with some of the most baffling paradoxes in physics. From
their original conception as dark stars, they have come to be understood as physical …

In this paper we analyze the interaction of a uniformly accelerated detector with a quantum
field in (3+ 1) D spacetime, aiming at the issue of how kinematics can render vacuum …

A bstract We study the time-dependence of quantum entanglement between two Unruh-
DeWitt detectors, one at rest in a Minkowski frame, the other non-uniformly accelerated in …

A bstract The Unruh effect refers to the thermal fluctuations a detector experiences while
undergoing linear motion with uniform acceleration in a Minkowski vacuum. This thermality …

A definition of nonequilibrium free energy F s is proposed for dynamical Gaussian quantum
open systems strongly coupled to a heat bath and the formal relation with the generating …

In this paper, we dwell on three issues:(1) revisit the relation between vacuum fluctuations
and radiation reaction in atom-field interactions, an old issue that began in the 1970s and …

The fluctuation-dissipation relations (FDR) are powerful relations which can capture the
essence of the interplay between a system and its environment. Challenging problems of …

In this note we review some recent results on corrections to the Casimir–Polder retardation
force due to atomic motion and present a preliminary critique on one recently proposed …

We employ the Schwinger-Keldysh formalism to study the nonequilibrium dynamics of the
mirror with perfect reflection moving in a quantum field. In the case where the mirror …

We study an exactly solvable model where a uniformly accelerated detector is linearly
coupled to a massless scalar field initially in the Minkowski vacuum. Using the exact …
