Published in 2018 at "Journal of Nonlinear Science"

DOI: 10.1007/s00332-017-9419-9

Abstract: In the exciton-polariton system, a linear dispersive photon field is coupled to a nonlinear exciton field. Short-time analysis of the lossless system shows that, when the photon field is excited, the time required for that… read more here.

Published in 2019 at "Accounts of chemical research"

DOI: 10.1021/acs.accounts.9b00382

Abstract: Lead halide perovskites (LHPs) are attractive material systems for light emission, thanks to the ease and diverse routes of synthesis, the broad tunability in color, the high emission quantum efficiencies, and the strong light-matter coupling… read more here.

DOI: 10.1021/acs.nanolett.2c00235

Abstract: We report the observation of coherent oscillations in the relaxation dynamics of an exciton-polariton condensate that were driven by parametric scattering processes. As a result of the interbranch scattering scheme and the nonlinear polariton-polariton interactions,… read more here.

Published in 2022 at "Nano letters"

DOI: 10.1021/acs.nanolett.3c01021

Abstract: The rotational response of quantum condensed fluids is strikingly distinct from rotating classical fluids, especially notable for the excitation and ordering of quantized vortex ensembles. Although widely studied in conservative systems, the dynamics of rotating… read more here.

Published in 2020 at "Nano letters"

DOI: 10.1021/acs.nanolett.9b04175

Abstract: Metallic halide perovskites are promising for low-cost, low-consumption, flexible optoelectronic devices. However, research is lacking on light propagation and dielectric behaviors as fundamental properties for optoelectronic perovskite applications, particularly the mechanism supporting strong light-matter interaction… read more here.

Published in 2018 at "ACS Photonics"

DOI: 10.1021/acsphotonics.8b00662

Abstract: Polaritons are quasiparticles arising from the strong coupling of electromagnetic waves in cavities and dipolar oscillations in a material medium. In this framework, localized surface plasmon in metallic nanoparticles defining optical nanocavities have attracted increasing… read more here.

Published in 2017 at "Scientific Reports"

DOI: 10.1038/s41598-017-09824-8

Abstract: We consider finite temperature effects in a non-standard Bose-Hubbard model for an exciton- polariton Josephson junction (JJ) that is characterised by complicated potential energy landscapes (PEL) consisting of sets of barriers and wells. We show… read more here.

Published in 2021 at "CrystEngComm"

DOI: 10.1039/d1ce00419k

Abstract: Achieving electrically-driven exciton–polaritons has drawn substantial attention toward developing ultralow-threshold coherent light sources, containing polariton laser devices and high-performance light-emitting diodes (LEDs). In this work, we demonstrate an electrically driven exciton–polariton LED, which is made… read more here.

Published in 2021 at "Physical Review A"

DOI: 10.1103/physreva.104.013318

Abstract: We propose a method of generating and detecting entanglement via spin squeezing in an exciton-polariton condensate. Spin squeezing is a sensitive detector of entanglement because any squeezing below shot noise implies entanglement. In our scheme,… read more here.
