Mechanistic principles of exciton-polariton relaxation

Ian Haines, Arshath Manjalingal, Logan Blackham +2

Exciton-polaritons are light-matter hybrid quasi-particles that have emerged as a flexible platform for developing quantum technologies and engineering material properties. However…

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…

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…

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…
