Description
In this talk, I will present recent and ongoing work on the application of semi-classical methods, such as the discrete truncated Wigner approximation and quantum state diffusion simulations, for simulating dissipative quantum spin models. Specifically, I will discuss the use of these techniques in the context of superradiance and demonstrate that, even in the presence of squeezing correlations in the photonic bath or strong disorder, semi-classical approaches involving little or no entanglement can accurately capture the superradiant decay process and provide new insights into the mechanisms underlying collectively enhanced emission. If time permits, I will also briefly discuss ongoing work on the steady states of dissipative Heisenberg models, where semi-classical methods enable the study of critical scaling relations for system sizes that are currently inaccessible with other approaches.
