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…
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…
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…
Topological anomalous Floquet photon pump
Manshuo Lin, Saeed Rahmanian Koshkaki, Mohsen Yarmohammadi +1
There is a close theoretical connection between topological Floquet physics and cavity QED, yet this connection has not been realized experimentally due to complicated cavity QED m…
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…
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…
Cavity induced many-body localization
Rong-Chun Ge, Saeed Rahmanian Koshkaki, Michael H. Kolodrubetz
In this manuscript, we explore the feasibility of achieving many-body localization in the context of cavity quantum electrodynamics at strong coupling. Working with a spinless elec…
Inverted many-body mobility edge in a central qudit problem
Saeed Rahmanian Koshkaki, Michael H. Kolodrubetz
Many interesting experimental systems, such as cavity QED or central spin models, involve global coupling to a single harmonic mode. Out-of-equilibrium, it remains unclear under wh…
Study of the effect of nearest neighbors on ferromagnetic to paramagnetic phase transition in 2D lattices by Monte Carlo algorithm
Saeed Rahmanian Koshkaki
In this work we try to use the Monte Carlo algorithm, metropolis, to study the behavior of 2D magnetic systems; honeycomb, hexagonal and square lattices. In this study we use Ising…
