Abstract

In this talk , I will introduce a new setup for powering a quantum clock with the non-thermal resources offered by the stationary state of an integrable quantum spin chain, driven out of equilibrium by a quantum quench in one of its parameters.
Analyzing the bias conditions of the clock, I will establish a direct connection with the negativity of the steady-state response function. Using experimentally relevant examples of spin chain batteries, I will suggest crossing a phase transition point is crucial for optimal performance. Even if the coupling takes place through a global observable, I will prove that the battery lifespan is extensive in its size.
