All-optical coherent quantum-noise cancellation in cascaded optomechanical systems
Jakob Schweer, Daniel Steinmeyer, Klemens Hammerer +1
Coherent quantum noise cancellation (CQNC) can be used in optomechanical sensors to surpass the standard quantum limit (SQL). In this paper, we investigate an optomechanical force…
Higher-order mean-field theory of chiral waveguide QED
Kasper J. Kusmierek, Sahand Mahmoodian, Martin Cordier +6
Waveguide QED with cold atoms provides a potent platform for the study of non-equilibrium, many-body, and open-system quantum dynamics. Even with weak coupling and strong photon lo…
Correlated steady states and Raman lasing in continuously pumped and probed atomic ensembles
Alexander Roth, Klemens Hammerer, Kirill S. Tikhonov
Spin-polarised atomic ensembles probed by light based on the Faraday interaction are a versatile platform for numerous applications in quantum metrology and quantum information pro…
