Giant optical spin-orbit interactions in ferroelectric van der Waals waveguides
Ding Xu, Saeed Rahmanian Koshkaki, Vicente Galicia +14
Optical spin-orbit interactions (SOI) link photonic spin to momentum, offering a route toward on-chip polarization control and beam steering. Nevertheless, achieving sufficient opt…
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…
Disorder induced topological phase transition in a driven Majorana chain
Henry Ling, Philip Richard, Saeed Rahmanian Koshkaki +4
We study a periodically driven one dimensional Kitaev model in the presence of disorder. In the clean limit our model exhibits four topological phases corresponding to the existenc…
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…
