The Unruh effect revisited
We give a complete and rigorous proof of the Unruh effect, in the following form. We show that the state of a two-level system, uniformly accelerated with proper acceleration a, and coupled to a scalar bose field initially in the Minkowski vacuum state will converge, asymptotically in the detector’s proper time, to the Gibbs state at inverse temperature β = 2π a . The result also holds if the f...
متن کاملUnruh Effect in Storage Rings
A uniformly accelerated system will get thermally excited due to interactions with the vacuum fluctuations of the quantum fields. This is the Unruh effect. Also a system accelerated in a circular orbit will be heated, but in this case complications arise relative to the linear case. An interesting question is in what sense the real quantum effects for orbital and spin motion of a circulating el...
متن کاملUnruh Effect for General Trajectories
We consider two-level detectors coupled to a scalar field and moving on arbitrary trajec-tories in Minkowski space-time. We first derive a generic expression for the response function using a (novel) regularization procedure based on the Feynmann prescription that is explicitly causal, and we compare it to other expressions used in the literature. We then use this expression to study, analytica...
متن کاملEntanglement Generation in the Unruh Effect
The master equation describing the completely positive time evolution of a uniformly accelerated two-level system in weak interaction with a scalar field in the Minkowski vacuum is derived and explicitly solved. It encodes the well known Unruh effect, leading to a purely thermal equilibrium state. This asymptotic state turns out to be entangled when the uniformly accelerating system is composed...
متن کاملEnergy Conservation and the Unruh Effect
In this paper it is explicitly demonstrated that the energy conservation law is kept when a detector uniformly accelerated in the Minkowski vacuum is excited and emits a particle. This fact had been hidden in conventional approaches in which detectors were considered to be forced on trajectories. To lift the veil we suggest the transition amplitude written in terms of the Minkowski coordinates....
