Semiclassical Phase-Space Dynamics of Emitter Ensembles with Local Dissipation
This work develops a scalable truncated Wigner approximation (TWA) to describe the semiclassical dynamics of permutation-invariant emitter ensembles with local dissipation. It maps quantum collective behavior onto a four-dimensional phase space, allowing for nonlinear simulations that capture nonclassical effects and collective dynamics across various system sizes.
