Stabilization of dark states in emitter arrays coupled to a half-waveguide
Oriol Rubies-Bigorda, Susanne F. Yelin, Ana Asenjo-Garcia +1
The radiative properties of quantum emitters are profoundly influenced by their electromagnetic environment. When coupled to a waveguide terminated at one end by a mirror, distant…
Phase-Space Methods for Many-Body Quantum Optics
Edgar Guardiola-Navarrete, Silvia Cardenas-Lopez, Ana Asenjo-Garcia
Many-body quantum-optical systems, where a collection of emitters interacts through a common electromagnetic reservoir, exhibit rich out-of-equilibrium behavior and hold promise fo…
Polaron-Polaritons in Subwavelength Arrays of Trapped Atoms
Kristian Knakkergaard Nielsen, Lukas Wangler, David Castells-Graells +4
Subwavelength arrays of atoms trapped in optical lattices or tweezers are inherently susceptible to deformations: Optomechanical forces displace atoms within their trapping potenti…
Steady-state spin order and superradiance beyond the Dicke limit
Silvia Cardenas-Lopez, Edgar Guardiola-Navarrete, Ana Asenjo-Garcia
Spontaneous collective decay in incoherently driven atomic ensembles can generate macroscopic coherence in the steady state, as exemplified by steady-state superradiance in single-…
Theory of quantum-enhanced interferometry with general Markovian light sources
Erfan Abbasgholinejad, Daniel Malz, Ana Asenjo-Garcia +1
Quantum optical systems comprising quantum emitters interacting with engineered optical modes generate non-classical states of light that can be used as resource states for quantum…
Optomechanical self-organization in a mesoscopic atom array
Jacquelyn Ho, Yue-Hui Lu, Tai Xiang +5
Increasing the number of particles in a system often leads to qualitative changes in its properties, such as breaking of symmetries and the appearance of phase transitions. This re…
Deterministic generation of photonic entangled states using decoherence-free subspaces
Oriol Rubies-Bigorda, Stuart J. Masson, Susanne F. Yelin +1
We propose the use of collective states of matter as a resource for the deterministic generation of quantum states of light, which are fundamental for quantum information technolog…
Ground-state selection via many-body superradiant decay
Wai-Keong Mok, Stuart J. Masson, Dan M. Stamper-Kurn +2
For a single particle, relaxation into different ground states is governed by fixed branching ratios determined by the transition matrix element and the environment. Here, we show…
Universal scaling laws for correlated decay of many-body quantum systems
Wai-Keong Mok, Avishi Poddar, Eric Sierra +3
Quantum systems are open, continually exchanging energy and information with the surrounding environment. This interaction leads to decoherence and decay of quantum states. In comp…
Collectively enhanced ground-state cooling in subwavelength atomic arrays
Oriol Rubies-Bigorda, Raphael Holzinger, Ana Asenjo-Garcia +6
Subwavelength atomic arrays feature strong light-induced dipole-dipole interactions, resulting in subradiant collective resonances characterized by narrowed linewidths. In this wor…
State-insensitive wavelengths for light shifts and photon scattering from Zeeman states
Stuart J. Masson, Zhenjie Yan, Jacquelyn Ho +3
Atoms are not two-level systems, and their rich internal structure often leads to complex phenomena in the presence of light. Here, we analyze off-resonant light scattering includi…
Super-radiant and Sub-radiant Cavity Scattering by Atom Arrays
Zhenjie Yan, Jacquelyn Ho, Yue-Hui Lu +3
We realize collective enhancement and suppression of light scattered by an array of tweezer-trapped Rb atoms positioned within a strongly coupled Fabry-Pérot optical cavity.…
Dynamical beats of short pulses in waveguide QED
Dianqiang Su, Yuan Jiang, Silvia Cardenas-Lopez +4
We study temporal oscillations, known as dynamical beats, developed by a propagating pulse due to its interaction with a near-resonant collective medium of Cs atoms randoml…
Dicke superradiance in ordered arrays of multilevel atoms
Stuart J. Masson, Jacob P. Covey, Sebastian Will +1
In inverted atomic ensembles, photon-mediated interactions give rise to Dicke superradiance, a form of many-body decay that results in a rapid release of energy as a photon burst.…
Dicke superradiance requires interactions beyond nearest-neighbors

Optical precursors in waveguide quantum electrodynamics
Silvia Cardenas-Lopez, Pablo Solano, Luis A. Orozco +1
When a broadband signal propagates through a dispersive medium, some frequency components move faster than the center of the pulse. This leads to the appearance of precursors, tran…
Dicke superradiance in ordered lattices: dimensionality matters
