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…
Probing topological phases in a perturbed Kane-Mele model via RKKY interaction: Application to monolayer jacutingaite PtHgSe
Mohsen Yarmohammadi, Saeed Rahmanian Koshkaki, Jamal Berakdar +2
Quantum spin Hall insulators (QSHIs) are promising for spintronics, leveraging strong spin-orbit coupling for efficient spin manipulation via electrical and optical methods, with p…
