A two-mode thermomechanically squeezed phonon laser - Nature Communications

Lasers find ubiquitous use in physics due to their coherence, spectral purity and high intensity. However, the output of a laser does not carry crucial resources such as squeezing and entanglement, and the generation of such properties requires the use of nonlinear media. In the electromagnetic domain, the nonlinearities are weak, resulting in sources of squeezing and entanglement that are not bright. In this work, we exploit the fact that stron…
