Quantum Fluctuation Dynamics of Dispersive Superradiant Pulses in a Hybrid Light-Matter System
Kevin Stitely, Fabian Finger, Rodrigo Rosa-Medina +5
We consider theoretically a driven-dissipative quantum many-body system consisting of an atomic ensemble in a single-mode optical cavity as described by the open Tavis-Cummings mod…
Spectral Engineering of Cavity-Protected Polaritons in an Atomic Ensemble with Controlled Disorder
Mohamed Baghdad, Pierre-Antoine Bourdel, Sylvain Schwartz +3
The paradigm of quantum emitters coupled to a single cavity mode appears in many situations ranging from quantum technologies to polaritonic chemistry. The ideal case of identi…
An optical elevator for precise delivery of cold atoms using an acousto-optical deflector
Francesco Ferri, Arthur La Rooij, Claire Lebouteiller +6
We implement a simple method for fast and precise delivery of ultracold atoms to a microscopic device, i.e. a Fabry-Perot microcavity. By moving a single beam optical dipole trap i…
Dissipation-engineered family of nearly dark states in many-body cavity-atom systems
Rui Lin, Rodrigo Rosa-Medina, Francesco Ferri +5
Three-level atomic systems coupled to light have the capacity to host dark states. We study a system of V-shaped three-level atoms coherently coupled to the two quadratures of a di…
Observing dynamical currents in a non-Hermitian momentum lattice
Rodrigo Rosa-Medina, Francesco Ferri, Fabian Finger +6
We report on the experimental realization and detection of dynamical currents in a spin-textured lattice in momentum space. Collective tunneling is implemented via cavity-assisted…
Emerging dissipative phases in a superradiant quantum gas with tunable decay
Francesco Ferri, Rodrigo Rosa-Medina, Fabian Finger +5
Exposing a many-body system to external drives and losses can transform the nature of its phases and opens perspectives for engineering new properties of matter. How such character…
Overlapping two standing-waves in a microcavity for a multi-atom photon interface
Sébastien Garcia, Francesco Ferri, Jakob Reichel +1
We develop a light-matter interface enabling strong and uniform coupling between a chain of cold atoms and photons of an optical cavity. This interface is a fiber Fabry-Perot cavit…
Continuous feedback on a quantum gas coupled to an optical cavity
Katrin Kroeger, Nishant Dogra, Rodrigo Rosa-Medina +4
We present an active feedback scheme acting continuously on the state of a quantum gas dispersively coupled to a high-finesse optical cavity. The quantum gas is subject to a transv…
Mapping standing-wave cavity modes with a commercial scanning near-field microscope tip
Francesco Ferri, Sébastien Garcia, Mohamed Baghdad +2
We describe a method to map the standing-wave pattern inside a Fabry-Perot optical cavity with sub-wavelength resolution by perturbing it with a commercially available scanning nea…
Dual-wavelength fiber Fabry-Perot cavities with engineered birefringence
Sébastien Garcia, Francesco Ferri, Konstantin Ott +2
We present a method to engineer the frequency splitting of polarization eigenmodes in fiber Fabry-Perot (FFP) cavities. Using specific pattern of multiple CO laser pulses, we m…
