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…
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…
Mean-field Mixed Quantum-Classical Approach for Many-Body Quantum Dynamics of Exciton-Polaritons
Pritha Ghosh, Arshath Manjalingal, Sachith Wickramasinghe +2
In this work, we use a mixed quantum-classical (mean-field) many-body approach for simulating the quantum dynamics of excitons and exciton-polaritons beyond the single-excitation s…
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…
Towards Accurate Mixed Quantum Classical Simulations of Vibrational Polaritonic Chemistry
Muhammad R. Hasyim, Arkajit Mandal, David R. Reichman
Interest in vibrational polaritonic chemistry, where ground-state chemical kinetics are modified via confined optical modes in a cavity, has surged in recent years. Although models…
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…
Microscopic Theory of Polaron-Polariton Dispersion and Propagation
Logan Blackham, Arshath Manjalingal, Saeed R. Koshkaki +1
We develop an analytical microscopic theory to describe the polaron-polariton dispersion, formed by hybridizing excitons, photons, and phonons, and their coherent dynamics inside o…
