Quantum field theory in curved spacetime
... quantum field theory when one allows for arbitrary, non-inertial observers. We begin by constructing a simple model of a particle detector moving along an arbitrary world line x(τ ) and discover that the particle content of the “vacuum” is entirely dependent on the state of motion of the detector, w ...

Quantum refrigerators and the third law of thermodynamics
... The rate of temperature decrease of a cooled quantum bath is studied as its temperature is reduced to absolute zero. The third law of thermodynamics is then quantified dynamically by evaluating the characteristic exponent ζ of the cooling process dTdt(t) ∼ −T ζ when approaching absolute zero, T → 0. ...

One useful result: for elastic collisions, the magnitude of the relative velocity is the same before and after the collision: |v1,i – v2,i | = |v1,f – v2,f | (This is true for elastic collisions in 2 and 3 dimensions as well). An important case is a particle directed at a stationary target (v2,i = ...
