Exceptional points in dissipative coupling polaron-polaritons
A. J. Vega-Carmona, D. A. Mendoza, A. Camacho-Guardian +1
Understanding how strong correlations and dissipation combine to shape collective quantum excitations is a central challenge in many-body physics. We investigate the effect of diss…
Charged Bose polarons at finite momentum
Grover Andrade-Sánchez, Arturo Camacho-Guardian
Charged impurities in quantum fluids have unveiled new classes of strongly correlated many-body states across condensed matter, ultracold gases, and hybrid atom-ion platforms. Whil…
Lattice polarons with extended interactions
Enrique I. RamÃrez-Juárez, Genaro Lopez-Olivera, Luis A. Peña Ardila +1
Lattice impurities have recently emerged as a platform in which polarons unveil new quantum many-body states absent in free space and can serve to probe strongly correlated matter.…
Observation of low-lying impurity states in Bose-Einstein condensates
A. M. Morgen, S. S. Balling, M. T. Strøe +6
Impurities embedded in a Bose-Einstein Condensate (BEC) of 39K atoms are investigated with a pump-probe ejection spectroscopy sequence. The spectroscopic signal exhibits a strong f…
Intercavity phonons and dynamics in coupled polariton cavities
Iliana Carmona-Moreno, Grover Andrade-Sánchez, Hugo A Lara-GarcÃa +2
Intercavity polaritons, hybrid quasiparticles with spatially separated photonic and excitonic components, provide a platform to engineer structured light-matter states. We show tha…
Effective Mass in Dissipative Coupled Polaritons
Diego A. Mendoza, Areli J. Vega-Carmona, Arturo Camacho-Guardian +1
Dissipative coupling refers to the effect where two systems interact with each other mediated by dissipation channels. Recent advances in controlling light-matter systems have open…
