Critical quantum metrology beyond adiabaticity in collectively pumped superradiance
Yoav Shimshi, Ephraim Shahmoon
Critical metrology relies on the high sensitivity of systems to parameter changes near a phase transition to extract information with high precision. Such methods usually require w…

Heisenberg-Langevin approach to driven superradiance
Ori Somech, Yoav Shimshi, Ephraim Shahmoon
We present an analytical approach for the study of driven Dicke superradiance based on a Heisenberg-Langevin formulation. We calculate the steady-state fluctuations of both the ato…
