“…Due to the ubiquitous nature of the mechanical motion, such resonators couple with many kinds of quantum devices, that range from atomic systems to the solid-state electronic circuits [33][34][35][36]. More recently, a new development has been made in the field of levitated optomechanics [37][38][39], in which the mechanical oscillator is supported only by the light field.…”

Control of Fano resonances and slow light using Bose-Einstein condensates in a nanocavity

In this study, a standing wave in an optical nanocavity with Bose-Einstein condensate (BEC) constitutes a one-dimensional optical lattice potential in the presence of a finite two bodies atomic interaction. We report that the interaction of a BEC with a standing field in an optical cavity coherently evolves to exhibit Fano resonances in the output field at the probe frequency. The behaviour of the reported resonance shows an excellent compatibility with the original formulation of asymmetric resonance as discovered by Fano [U. Fano, Phys. Rev. 124, 1866(1961]. Based on our analytical and numerical results, we find that the Fano resonances and subsequently electromagnetically induced transparency of the probe pulse can be controlled through the intensity of the cavity standing wave field and the strength of the atom-atom interaction in the BEC. In addition, enhancement of the slow light effect by the strength of the atom-atom interaction and its robustness against the condensate fluctuations are realizable using presently available technology.

“…Also ions are proposed as transducers for electromechanical oscillators [13] while other proposals involve the coupling between oscillators and dipolar molecules [14]. A growing interest, both theoretical and experimental, is therefore apparent in the study of nanomechanical oscillators and their interaction with other quantum systems [4,15].…”

The dynamics of a quantum anharmonic oscillator whose position is monitored by a Bose-Einstein condensate (BEC) trapped in a symmetric double well potential is studied. The (non-exponential) decoherence induced on the oscillator by the measuring device is analysed. A detailed quasiclassical and quantum analysis is presented. In the first case, for an arbitrary initial coherent state, two different decoherence regimes are observed: An initial Gaussian decay followed by a power law decay for longer times. The characteristic time scales of both regimes are reported. Analytical approximated expressions are obtained in the full quantum case where algebraic time decay of decoherence is observed.

“…NR has also been used to study quantum nondemolition measurement [13,14,15,16], quantum decoherence [12,17], and macroscopic quantum coherence phenomena [18]. The fast advance in the tecnique of fabrication in nanotecnology implied great interest in the study of the NR system in view of its potential modern applications, as a sensor, largely used in various domains, as in biology, astronomy, quantum computation [19,20], and more recently in quantum information [3,21,22,23,24,25,26] to implement the quantum qubit [22], multiqubit [27] and to explore cooling mechanisms [28,29,30,31,32,33], transducer techniques [34,35,36], and generation of nonclassical states, as Fock [37], Schrödinger-"cat" [12,38,39], squeezed states [40,41,42,43,44], including intermediate and other superposition states [45,46]. In particular, NR coupled with superconducting charge qubits has been used to generate entangled states [12,38,47,48].…”

We propose a scheme to create holes in the statistical distribution of excitations of a nanomechanical resonator. It employs a controllable coupling between this system and a Cooper pair box. The success probability and the fidelity are calculated and compared with those obtained in the atom-field system via distinct schemes. As an application we show how to use the hole-burning scheme to prepare (low excited) Fock states.
