- Abstract: Light-matter interaction in the ultrastrong coupling regime can be used to
generate exotic ground states with two-mode squeezing and may be of use for
quantum enhanced sensing. Current demonstrations of ultrastrong coupling have
been performed in fundamentally nonlinear systems. We report a cavity
optomechanical system that operates in the linear coupling regime, reaching a
maximum coupling of $g_x/\Omega_x=0.55\pm 0.02$. Such a system is inherently
unstable, which may in the future enable strong mechanical squeezing.

noise [0.0]
We show that while the strength of the nonlinearity is generally reduced by a Markovian bath spectrum, it can be enhanced by constructing a bath with a highly non-Markovian structure.
The results have potential implications for future optomechanical experiments which seek to achieve a strong optomechanical nonlinearity.

We propose two schemes for generating Wigner-negative entangled states unconditionally in mechanical resonators.
We show analytically that both schemes stabilize a Wigner-negative entangled state that combines the entanglement of a two-mode squeezed vacuum with a cubic nonlinearity.
We then perform extensive numerical simulations to test the robustness of Wigner-negative entanglement attained by approximate CPE states stabilized in the presence of thermal decoherence.

We experimentally observe the parity symmetry breaking of an ancillary Xmon artificial atom induced by the field of a lumped-element superconducting resonator.
This result opens a way to experimentally explore the novel quantum-vacuum effects emerging in the deep-strong coupling regime.

The combination of the inherent open nature of the system and the strong optomechanical coupling leads to emerging parity-time (PT) symmetry.
The $mathcalPT$ phase transition drives long-living subradiant states, observable in the state-of-the-art waveguide QED setups.
