Negative cavity photon spectral function in an optomechanical system with two parametrically-driven mechanical modes
Ali Motazedifard, A. Dalafi, M. H. Naderi
We propose an experimentally feasible optomechanical scheme to realize a negative cavity photon spectral function (CPSF) which is equivalent to a negative absorption. The system un…
Homodyne coherent quantum noise cancellation in a hybrid optomechanical force sensor
H. Allahverdi, Ali Motazedifard, A. Dalafi +2
In this paper, we propose an experimentally viable scheme to enhance the sensitivity of force detection in a hybrid optomechanical setup assisted by squeezed vacuum injection, beyo…
Ultra-precision quantum sensing and measurement based on nonlinear hybrid optomechanical systems containing ultracold atoms or atomic Bose-Einstein condensate
Ali Motazedifard, A. Dalafi, M. H. Naderi
In this review, we study how a hybrid optomechanical system (OMS), in which a quantum micro- or nano-mechanical oscillator (MO) is coupled to the electromagnetic (EM) radiation pre…
A Green's function approach to the linear response of a driven dissipative optomechanical system
Ali Motazedifard, A. Dalafi, M. H. Naderi
In this paper, we first try to shed light on the ambiguities that exist in the literature in the generalization of the standard linear response theory (LRT) which has been basicall…
Entanglement sudden birth and sudden death in a system of two distant atoms coupled via an optical element
Maryam Ashrafi, M. H. Naderi
An investigation is reported of the collective effects and the dynamics of atom atom entanglement in a system of two distant two level atoms which are coupled via an optical elemen…
Quantum correlations in optomechanical crystals
F. Bemani, R. Roknizadeh, A. Motazedifard +2
The field of optomechanics provides us with several examples of quantum photon-phonon interface. In this paper, we theoretically investigate the generation and manipulation of quan…
