Stochastic scattering theory for excitation induced dephasing: Time-dependent nonlinear coherent exciton lineshapes

Ajay Ram Srimath Kandada, Hao Li, Félix Thouin +2

We develop a stochastic theory that treats time-dependent exciton-exciton s-wave scattering and that accounts for dynamic Coulomb screening, which we describe within a mean-field l…

Stochastic scattering theory for excitation induced dephasing: Comparison to the Anderson-Kubo lineshape

Hao Li, Ajay Ram Srimath Kandada, Carlos Silva +1

In this paper we present a quantum stochastic model for spectroscopic line-shapes in the presence of a co-evolving and non-stationary background population of excitations. Starting…

Probing exciton/exciton interactions with entangled photons: theory

Eric R. Bittner, Hao Li, Andrei Piryatinski +2

Quantum entangled photons provide a sensitive probe of many-body interactions and offer an unique experimental portal for quantifying many-body correlations in a material system. I…

Electron-phonon couplings inherent in polarons drive exciton dynamics in two-dimensional metal-halide perovskites

Félix Thouin, Ajay Ram Srimath Kandada, David A. Valverde-Chávez +6

We report on the exciton formation and relaxation dynamics following photocarrier injection in a single-layer two-dimensional lead-iodide perovskite. We probe the time evolution of…

Enhanced screening and spectral diversity in many-body elastic scattering of excitons in two-dimensional hybrid metal-halide perovskites

Félix Thouin, Daniele Cortecchia, Annamaria Petrozza +2

In two-dimensional hybrid organic-inorganic metal-halide perovskites, the intrinsic optical lineshape reflects multiple excitons with distinct binding energies, each dressed differ…

Phonon coherences reveal the polaronic character of excitons in two-dimensional lead-halide perovskites

Félix Thouin, David A. Valverde Chávez, Claudio Quarti +6

Hybrid organic-inorganic semiconductors feature complex lattice dynamics due to the ionic character of the crystal and the softness arising from non-covalent bonds between molecula…

Photon entanglement entropy as a probe of many-body correlations and fluctuations

Hao Li, Andrei Piryatinski, Ajay Ram Srimath Kandada +2

Recent theoretical and experiments have explored the use of entangled photons as a spectroscopic probe of material systems. We develop here a theoretical description for entropy pr…

Incoherent population mixing contributions to phase-modulation two-dimensional coherent excitation spectra

Pascal Grégoire, Ajay Ram Srimath Kandada, Eleonora Vella +2

We present theoretical and experimental results showing the effects of incoherent population mixing on two-dimensional (2D) coherent excitation spectra that are measured via a time…
