DOI: 10.1007/s11128-017-1678-8
Abstract: In this paper, we investigate the influence of the Unruh effects on the coherence dynamics in an open quantum system which is subject to a nondissipative flip channel. We find that Unruh effect does not… read more here.

DOI: 10.1016/j.wavemoti.2019.102462
Abstract: We consider a point-like observer that moves in a medium illuminated by noise sources with Lorentz-invariant spectrum. We show that the autocorrelation function of the signal recorded by the observer allows it to perceive its… read more here.

DOI: 10.1088/1361-6382/aad13a
Abstract: We calculate the trajectories which maximize the Unruh effect, mode by mode, when given a fixed energy budget for acceleration. We find that Unruh processes are most likely to occur, and therefore potentially best observable,… read more here.

DOI: 10.1103/physrevd.101.024047
Abstract: We study memory effects as information backflow for an accelerating two-level detector weakly interacting with a scalar field in the Minkowski vacuum. This is the framework of the well-known Unruh effect: the detector behaves as… read more here.

DOI: 10.1103/physrevd.104.125014
Abstract: We study the influence of the thermal background on the existence of the anti-Unruh effect. For the massless scalar field, we present that the anti-Unruh effect can appear when the detector is accelerated in the… read more here.

DOI: 10.1103/physrevd.107.085001
Abstract: We investigate the transition of a two-level atom as the Unruh-Dewitt detector accelerated in the electromagnetic field in this paper. The enhancement of the transition probability is found for different field states under the conditions… read more here.

DOI: 10.1103/physrevd.95.101701
Abstract: We study the Unruh Effect for a wide class of nonlocal theories. Using the approach of Bogoliubov coefficients, we show that the Unruh Effect remains entirely unmodified in these theories. However, for those nonlocal theories… read more here.

DOI: 10.1103/physrevd.96.045017
Abstract: We point out that, when the Unruh-DeWitt detector couples to a scalar primary operator of $d$-dimensional conformal field theory, the detector's power spectrum generally obeys the thermal distribution for $(1+1)$-dimensional anyons. read more here.

DOI: 10.1103/physrevd.97.044016
Abstract: In this paper we prove the universal nature of the Unruh effect in a general class of weakly nonlocal field theories. At the same time we solve the tension between two conflicting claims published in… read more here.

DOI: 10.1134/s0202289319030071
Abstract: The Unruh effect for a massless scalar field in (1 + 1)D space-time is considered. It is shown that, under some natural assumptions like finiteness of the integration volume or finiteness of the interaction (propagation… read more here.
