Mode-Selective and Anharmonicity-Controlled Energy Transport in Cavity-Coupled Water
Sachith Wickramasinghe, Michael Fowler, Gerrit Groenhof +1
Recent experiments demonstrate the modification of chemical dynamics via cavity-enhanced vibrational energy transport. Here, we provide a microscopic account of both photonic and m…
Multiconfigurational Mixed Quantum-Classical Approach for Correlated Many-Body Dynamics
Pritha Ghosh, Rajanya Sarkar, Arkajit Mandal
In this work, we introduce a multiconfigurational mixed quantum-classical many-body approach for simulating the finite-temperature correlated multi-exciton dynamics in the presence…
On-the-Fly Cavity-Molecular Dynamics of Vibrational Polaritons
Sachith Wickramasinghe, Amirhosein Amini, Arkajit Mandal
In this work, we combine the density functional tight-binding (DFTB) approach with a light-matter Hamiltonian beyond the long-wavelength approximation to propagate the dynamics of…
Mixed Quantum-Classical Methods for Polaron Spectral Functions
Haimi Nguyen, Arkajit Mandal, Ankit Mahajan +1
In this work, using two distinct semiclassical approaches, namely the mean-field Ehrenfest (MFE) method and the mapping approach to surface hopping (MASH), we investigate the spect…
Exciton-Polariton Dynamics in Multilayered Materials
Saeed Rahmanian Koshkaki, Arshath Manjalingal, Logan Blackham +1
Coupling excitons with quantized radiation has been shown to enable coherent ballistic transport at room temperature inside optical cavities. Previous theoretical works employ a si…
Tilted Material in an Optical Cavity: Light-Matter Moiré Effect and Coherent Frequency Conversion
Arshath Manjalingal, Saeed Rahmanian Koshkaki, Logan Blackham +1
Exciton-polaritons formed inside optical cavities offer a highly tunable platform for exploring novel quantum phenomena. Here, we introduce and theoretically characterize a light-m…
