In a closely packed ensemble of quantum emitters, cooperative effects are typically suppressed due to the dephasing induced by the dipole-dipole interactions. Here, we show that by adding sufficiently strong collective dephasing, cooperative effects can be restored. Specifically, we show that the dipole force on a closely packed ensemble of strongly driven two-level quantum emitters, which collectively dephase, is enhanced in comparison to the dipole force on an independent noninteracting…

Collective Effects in Casimir-Polder Forces.
This work finds that a one-dimensional chain of emitters prepared in a super- or subradiant state experiences an enhanced or suppressed collective vacuum-induced force, respectively, which demonstrates the potential of collective phenomena as a new tool to selectively tailor vacuum forces.
Non-hermitian Hamiltonian description for quantum plasmonics: from dissipative dressed atom picture to Fano states
We derive effective Hamiltonians for a single dipolar emitter coupled to a metal nanoparticle (MNP) with particular attention devoted to the role of losses. For small particles sizes, absorption
Cooperative emission in quantum plasmonic superradiance
Plasmonic superradiance originates from the plasmon mediated strong correlation that builds up between dipolar emitters coupled to a metal nanoparticle. This leads to a fast burst of emission so that
Electromagnetically induced transparency of interacting Rydberg atoms with two-body dephasing.
It is shown that strong two-body dephasing can enhance the excitation blockade of neighboring Rydberg atoms, and provides a setting to explore and understand two- body dephase dynamics in many-body systems.

It is shown that using a fully quantum parametric amplifier can cause the simultaneous decay of two atoms and, in turn, create stabilized atomic Schrödinger cat states, which can have an extremely long lifetime.

Strong coupling and long-range collective interactions in optomechanical arrays.
We investigate the collective optomechanics of an ensemble of scatterers inside a Fabry-Pérot resonator and identify an optimized configuration where the ensemble is transmissive, in contrast to the
Universal quantum computation in waveguide QED using decoherence free subspaces
The interaction of quantum emitters with one-dimensional photon-like reservoirs induces strong and long-range dissipative couplings that give rise to the emergence of the so-called decoherence free
Enhanced Optical Cross Section via Collective Coupling of Atomic Dipoles in a 2D Array.
It is shown how dipolar interactions can suppress off-axis scattering in a two-dimensional atomic array, leading to a subradiant collective mode where the optical cross section is enhanced by almost an order of magnitude, implying high-fidelity extinction, from a monolayer.

Deterministic Generation of Arbitrary Photonic States Assisted by Dissipation.
A protocol makes use of decoherence-free subspaces for the atomic emitters with coherent evolution within the DFSs enforced by strong dissipative coupling to the waveguide to generation of many-body entangled states and for the reversible mapping of these states of matter to photonic states of an optical pulse in the wave guide.
