Emergence of Unruh prethermalization for uniformly accelerating many-atom system
Saptarshi Saha, Chiranjeeb Singha, Pragna Das +1
A uniformly accelerated atom in an inertial vacuum generally thermalizes and reaches a Gibbs state. This phenomenon is commonly known as the Unruh effect. Here, we show that the si…

Can a pure state remain pure in the Unruh effect?
Saptarshi Saha, Arpan Chatterjee, Chiranjeeb Singha
A uniformly accelerated detector in an inertial vacuum undergoes an unavoidable dissipation, and the final steady-state becomes thermal. However, to attain such a mixed state, ther…
