We consider the “membrane in the middle” optomechanical model consisting of a laser pumped cavity which is divided in two by a flexible membrane that is partially transmissive to light and subject to radiation pressure. Steady state solutions at the mean‐field level reveal that there is a critical strength of the light‐membrane coupling above which there is a symmetry breaking bifurcation where the membrane spontaneously acquires a displacement either to the left or the right. This bifurcation… 
Observation of optomechanical buckling transitions
TLDR
The observation of first- and second-order buckling transitions between stable mechanical states in an optomechanical system, in which full control of the nature of the transition is obtained by means of the laser power and detuning.

Emergence of singularities from decoherence: Quantum catastrophes
When two Bose-Einstein condensates are suddenly coupled by a tunneling junction, the Gross-Pitaevskii mean-field theory predicts that caustics will form in the number-difference probability
Catastrophes in non-equilibrium many-particle wave functions: universality and critical scaling
As part of the quest to uncover universal features of quantum dynamics, we study catastrophes that form in simple many-particle wave functions following a quench, focusing on two-mode systems that
Collective couplings: Rectification and supertransmittance.
TLDR
This work investigates heat transport between two thermal reservoirs that are coupled via a large spin composed of N identical two-level systems and finds a cooperatively enhanced rectification effect due to the interplay of supertransmittant heat currents and the asymmetric coupling to both reservoirs.

Photonic Josephson effect, phase transitions, and chaos in optomechanical systems
A photonic analog of the Josephson effect is analyzed for a system formed by a partly transparent mechanical membrane dividing an optical cavity into two halves. Photons tunneling between the two

We present the results of theoretical and experimental studies of dispersively coupled (or ‘membrane in the middle’) optomechanical systems. We calculate the linear optical properties of a high

We discuss a mean-field quantum-mechanical model which describes the dynamics of a homogeneously broadened system of two-level atoms contained in a pencil-shaped resonant cavity and driven by a
Dicke quantum phase transition with a superfluid gas in an optical cavity
TLDR
The Dicke quantum phase transition is realized in an open system formed by a Bose–Einstein condensate coupled to an optical cavity, and the emergence of a self-organized supersolid phase is observed.
Emergent crystallinity and frustration with Bose–Einstein condensates in multimode cavities
We propose that condensed-matter phenomena involving the spontaneous emergence and dynamics of crystal lattices can be realized using Bose–Einstein condensates coupled to multimode optical cavities.
Strong dispersive coupling of a high-finesse cavity to a micromechanical membrane
TLDR
A cavity which is detuned by the motion of a 50-nm-thick dielectric membrane placed between two macroscopic, rigid, high-finesse mirrors is demonstrated, which segregates optical and mechanical functionality to physically distinct structures and avoids compromising either.
Real-time observation of fluctuations at the driven-dissipative Dicke phase transition
TLDR
Using a dissipation channel to nondestructively gain information about a quantum many-body system provides a unique path to study the physics of driven-dissipative systems.

In this paper we consider a bosonic Josephson junction described by a two-mode Bose-Hubbard model, and we thoroughly analyze a quantum phase transition occurring in the system in the limit of
