SPICE Workshop on Quantum Spinoptics, June 18th - June 20th 2024

Large systems of interacting spins subject to drive and dissipation can exhibit a range of non-trivial behaviour, and can be realized experimentally in a number of different platforms. I’ll discuss work showing how a subtle form of time-reversal symmetry can be used in many cases to yield exact, analytic insights into the non-equilibrium steady states of such systems. Time permitting, I will discuss two very different kinds of exactly solvable systems: a driven, disordered set of two level atoms subject to both collective superradiant decay and single-atom decay (relevant to recent experiments seeing evidence of a dissipative phase transition), and boundary driven XXZ spin chains exhibiting a surprising kind of steady-state phase transition.
