Strong, steady-state mechanical squeezing below the vacuum level is theoretically possible for a levitated nanoparticle by combining parametric trap modulation with dissipative cooling of a Bogoliubov mode via coherent scattering.
We thus obtain c(t) = √ 2κ ∫ t 0 dτe−(κ+i∆)(t−τ)cin(τ) +iλ 2 [1 +α cos(2ωxt +φ)] ( be−iωxt κ +i(∆−ωx) + b†eiωxt κ +i(∆ +ωx) )
