Multiple electromechanically-induced-transparency windows and Fano resonances in hybrid nano-electro-optomechanics

Control of electromagnetically induced transparency and Fano resonances in a hybrid optomechanical system

“…To discuss the control of EIT and Fano resonances, we choose the feasible parameters from the recent available experiments [11,16]. Few of parameters are also taken from recent available theoretical work closer to experiment [7,26,27,44]. We consider 2.23 × N = 10 5 87 Rb atoms are trapped inside the Fabry Pérot cavity of length L = 25 mm.…”

“…EIT has been widely studied both theoretically [20,21] and experimentally in optical cavities [22,23] as well as in microcavities [24,25]. Further, a similar study to EIT has been recently reported in a nano-electromechanical system [26][27][28]. Furthermore, the investigation of EIT not only discussed in a single cavity system [29] but also a detailed analysis has been given in a two-mode cavity optomechanical system [30,31].…”

“…In the previous study [27], we have discussed electromechanically induced transparency (EMIT) and Fano resonances in a non-interacting ultracold two-level atoms. Here, we consider interacting ultracold gas trapped inside the cavity.…”

Multilevel Laser Induced Continuum Structure

“…Coherent manipulation of quantum states is at the core of contemporary quantum physics. The development of analytical models [1][2][3][4][5][6] treating laser interaction between two, three, and more levels [7,8] is fundamental for the understanding and the demonstration of effects like rapid adiabatic passage (RAP) [9], stimulated Raman adiabatic passage (STIRAP) [10], and electromagnetically induced transparency (EIT) [11][12][13], to name just a few. Generally, the problems of coherent population transfer and state preparation involve only bound states that lie deep inside the potential of the atom, which have well defined discrete energies.…”
