Temperature-Induced Crossover of Coherent Phonon Mechanisms in Chiral 2D Perovskites
Katherine A Koch, Matthew P Hautzinger, Matthew C Beard +1
The coupling between electronic excitations and lattice degrees of freedom fundamentally dictates the optoelectronic functionality of hybrid perovskites. While the potential energy…
Scattering theory of frequency-entangled biphoton states facilitated by cavity polaritons
Andrei Piryatinski, Nishaant Jacobus, Sameer Dambal +3
The use of quantum light to probe exciton properties in semiconductor and molecular nanostructures typically occurs in the low-intensity regime. A substantial enhancement of excito…
Biexcitons in Ruddlesden-Popper Metal Halides Probed by Nonlinear Coherent Spectroscopy
Katherine A. Koch, Carlos Silva-Acuña, Ajay Ram Srimath Kandada
Excitons and their correlated complexes underpin the rich photophysics of quantum-confined semiconductors. Among these, biexcitons -- bound states of two electrons and two holes --…
Resolving exciton and polariton multi-particle correlations in an optical microcavity in the strong coupling regime
Victoria Quirós-Cordero, Esteban Rojas-Gatjens, MartÃn Gómez-Dominguez +7
Multi-particle correlations of exciton-polaritons and reservoir-excitons in the strong light-matter coupling regime dictate the quantum dynamics of optical microcavities. In this l…
Nonlinear Dynamics in the Formation of Molecular Polariton Condensates
Evan J Kumar, Katherine A Koch, Rishabh Kaurav +5
Exciton-polaritons - hybrid light-matter quasiparticles - can undergo Bose-Einstein-like condensation at elevated temperatures owing to their lower effective mass. This becomes eve…
Lyapunov Dynamics in Entangled Biphoton Spectroscopy
Sameer Dambal, Ajay Ram Srimath Kandada, Eric R. Bittner
We develop a Lyapunov-based framework to model the evolution of entangled biphotons interacting with cavity and material modes. Using Gaussian-preserving dynamics and Møller opera…
