Authors: Carrillo-Bohorquez, Orlando; Valdes, Alvaro; Prosmiti, Rita Journal: CHEMPHYSCHEM Publication date: 2022/03/14 DOI: 10.1002/cphc.202200034 Abstract: We explore the origin of the anomalous splitting of the 1(01) levels reported experimentally for the H2O@C-60 endofullerene, in order to give some insight about the physical interpretations of the symmetry breaking observed. We performed fully-coupled quantum computations within the [...]

Tunable Directional Emission and Collective Dissipation with Quantum Metasurfaces

Marcelo Castellanos2023-02-21T13:37:05+01:00Tags: Multidisciplinary. , Physics|

Authors: Fernandez-Fernandez, D.; Gonzalez-Tudela, A. Journal: PHYSICAL REVIEW LETTERS Publication date: 2022/03/14 DOI: 10.1103/PhysRevLett.128.113601 Abstract: Subwavelength atomic arrays, recently labeled as quantum metamaterials, have emerged as an exciting platform for obtaining novel quantum optical phenomena. The strong interference effects in these systems generate subradiant excitations that propagate through the atomic array with very long lifetimes. [...]

Out-of-time-order correlator in the quantum Rabi model

Marcelo Castellanos2023-02-21T13:37:02+01:00Tags: Atomic, Molecular & Chemical. , Optics; Physics|

Authors: Kirkova, Aleksandrina, V; Porras, Diego; Ivanov, Peter A. Journal: PHYSICAL REVIEW A Publication date: 2022/03/25 DOI: 10.1103/PhysRevA.105.032444 Abstract: We investigate signatures of chaos and equilibration in the quantum Rabi model, which exhibits a quantum phase transition when the ratio of the atomic level-splitting to bosonic frequency grows to infinity. We show that the out-of-time-order [...]

Connecting steady-states of driven-dissipative photonic lattices with spontaneous collective emission phenomena

Marcelo Castellanos2023-02-21T13:37:02+01:00Tags: Multidisciplinary. , Physics|

Authors: Gonzalez-Tudela, Alejandro Journal: NEW JOURNAL OF PHYSICS Publication date: 2022/04/01 DOI: 10.1088/1367-2630/ac58b7 Abstract: Recent experimental advances enable the fabrication of photonic lattices in which the light propagates with engineered energy dispersions. When interfaced with quantum emitters, such systems yield strong collective spontaneous emission phenomena, such as perfect sub-radiance, in which the decay into the [...]
