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
TLDR
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
TLDR
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.

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
