Steady-state solutions of a hybrid system involving atom-light and optomechanical interactions: Beyond the weak-cavity-field approximation

Duality and bistability in an optomechanical cavity coupled to a Rydberg superatom

“…Heretofore, our Hamiltonian (1) is analogous to those in Refs. [5,6] except for the last term describing the DDI between the Rydberg atoms. We will focus only on the new optomechanical features resulting from DDI as expressed by a vdW potential…”

“…For instance, the mutual back-actions between movable mirrors and cavity fields could result in such applications as sensitive force detecting [11], mirror ground-state cooling [12][13][14][15][16][17], and quantum entanglement generation [18,19]. We also note that it is available to examine a few rich and complex nonlinear phenomena when cold atoms are further introduced to realize the mutual influence between atom-light interaction and optomechanical interaction [6]. In Ref.…”

“…So far most investigations on atom-assisted optomechanics consider movable cavities containing independent cold atoms driven to different configurations by quantum cavity fields and classical pumping fields [3][4][5][6]. But very recently Rydberg atoms, coupled via dipole-dipole interactions (DDI), have been shown to be efficient nonlinear media in cavities for pursuing additional control possibilities of optomechanical * liyong@csrc.ac.cn † jhwu@nenu.edu.cn interactions and applications [21].…”

“…It is also known that cavity fields may drive movable cavity mirrors to vibrate at eigen frequencies via radiation pressures while mirror vibrations will reciprocally modulate mode frequencies of cavity fields [2]. Typical optomechanical cavities with one or more movable mirrors are attracting increasing attention [3][4][5][6] as the hybrid optomechanical coupling is well exploited in the realization of quantum information processing [7][8][9] and in the observation of macroscopic quantum behaviors [10]. For instance, the mutual back-actions between movable mirrors and cavity fields could result in such applications as sensitive force detecting [11], mirror ground-state cooling [12][13][14][15][16][17], and quantum entanglement generation [18,19].…”

“…In Ref. [6], cold atoms in an optomechanical cavity are driven into the -type level configuration by a quantum cavity field and a classical pumping field in the regime of electromagnetically induced transparency (EIT) [20].…”
