Quantum scattering as a work source

We consider a collision between moving particle and fixed system, each having internal degrees of freedom. identify the regime where motion acts as work source for joint leading to energy changes which preserve entropy. This arises when has high kinetic its quantum state is broad in momentum narrow space, whether pure or mixed. In this case, scattering map ruling dynamics freedom becomes unitary equivalent that time-dependent interaction colliding systems. It follows lost by during autonomous coincides with performed interaction. Recently, collisions particles were shown act heat sources under suitable conditions; here we show they can also sources. opens interesting perspectives thermodynamics formulations within theory.
