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…

Optical depth dictates universal bounds on many-body decay in atomic ensembles

Cosimo C. Rusconi, Eric Sierra, Wai-Keong Mok +3

Cooperative emission is well understood for idealized symmetric systems, but its limits in spatially extended, free-space ensembles remain an open question. Here, we derive a unive…

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…

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…

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…
