A single phonon in a nonlinear nanomechanical resonator (NAMR) can block the excitation of a second phonon [Phys. Rev. A 82, 032101 (2010)]. This intrinsically quantum effect is called phonon blockade, and is an analog of Coulomb blockade and photon blockade. Here we predict tunable multiphonon blockade in coupled nonlinear NAMRs, where nonlinearity is induced by two-level systems (TLSs) assuming dispersive (far off-resonance) interactions. Specifically, we derive an effective Kerr-type… 
Phonon blockade in a nanomechanical resonator quadratically coupled to a two-level system
Phonon statistics in a nanomechanical resonator (NAMR) is investigated by driving the NAMR and two-level system simultaneously and shows the crossover from the UCPNB to the conventional phonon blockade (CPNB), which is induced by the strong nonlinear interaction of the system.
Phonon blockade in a nanomechanical resonator resonantly coupled to a qubit
We study phonon statistics in a nanomechanical resonator (NAMR) which is resonantly coupled to a qubit. We find that there are two different mechanisms for phonon blockade in such a resonantly
Optically induced phonon blockade in an optomechanical system with second-order nonlinearity
Quantum control of phonons has being become a focus of attention for developing quantum technologies. Here, we propose a proposal to realize phonon blockade in a quadratically coupled optomechanical
Tunable phonon blockade in weakly nonlinear coupled mechanical resonators via Coulomb interaction
It is shown that phonon blockade could be achieved in a system of two weakly nonlinear mechanical resonators coupled by a Coulomb interaction, and that via a radiation pressure induced coupling in an optomechanical cavity, phonon correlations can be measured indirectly in terms of photon correlations of the cavity mode.
Unconventional phonon blockade via atom-photon-phonon interaction in hybrid optomechanical systems.
Phonon nonlinearities play an important role in hybrid quantum networks and on-chip quantum devices. We investigate the phonon statistics of a mechanical oscillator in hybrid systems composed of an
Nonreciprocal Phonon Blockade in a Spinning Acoustic Ring Cavity Coupled to a Two-Level System
Quantum nonreciprocal devices have received extensive attention in recent years because they can be used to realize unidirectional quantum routing and noise isolation. In this work, we show that the
Hybrid photon-phonon blockade
We describe a novel type of blockade in a hybrid mode generated by linear coupling of photonic and phononic modes. We refer to this effect as hybrid photon-phonon blockade and show how it can be
Phonon blockade and strong anti-correlation between phonons and phonons in the optomechanical system with an auxiliary mechanical oscillator
Here we propose a scheme to realize phonon blockade in a cascaded coupling optomechanical system, where a quadratically coupled optomechanical system couples with a mechanical oscillator. The strong

We propose an unconventional photon blockade scheme in coupled semiconductor microcavities embedded in a nonlinear Kerr medium in the presence of photon leakage and bimodal driving on two cavity
Phonon antibunching effect in coupled nonlinear micro/nanomechanical resonator at finite temperature
In this study, we investigate the phonon antibunching effect in a coupled nonlinear micro/nanoelectromechanical system (MEMS/NEMS) resonator at a finite temperature. In the weak driving limit, the


Qubit-induced phonon blockade as a signature of quantum behavior in nanomechanical resonators
The observation of quantized nanomechanical oscillations by detecting femtometer-scale displacements is a significant challenge for experimentalists. We propose that a phonon blockade can serve as a
Two-photon and three-photon blockades in driven nonlinear systems
Photon blockade, in analogy to Coulomb’s or phonon blockade s, is a phenomenon when a single photon in a nonlinear cavity blocks the transmission of a second photon. This effect can occur in

In recent studies [Liew et al., Phys. Rev. Lett. 104, 183601 (2010); Bamba et al., Phys. Rev. A 83, 021802(R) (2011)], due to destructive interference between different paths for two-photon
