Optical Transmission of 2D Material with Quantum Anomalous Hall Effect
Nathan Pravda, Oleg L. Berman, Klaus Ziegler
We study the optical properties of gapped two-dimensional materials which are subject to the quantum anomalous Hall effect. At sufficiently low temperatures the transmission, refle…
Monitoring photon entanglement in coupled cavities
Moises Acero, Jeremiah Harrington, Oleg L. Berman +1
We study the dynamics of photons in a Fock state, initially located inside one cavity, and coupled by an optical fiber to a second cavity. The entanglement of the photons is mo…
Theory of two-component superfluidity of microcavity polaritons
A. Nafis Arafat, Oleg L. Berman, Godfrey Gumbs +1
We develop a microscopic mean-field theory describing the coexistence of Bose-Einstein condensates of upper and lower polaritons (UP/LP) in a semiconductor microcavity. Incorporati…
Enhanced polariton interaction in the presence of disorder
Matthew Prest, Cassandra Imperato, Oleg L. Berman +2
We consider the interaction between exciton-polaritons in a semiconductor quantum well, embedded in a microcavity, in the presence of disorder. The disorder acts on the excitons in…
Tuning excitons and superfluidity of dipolar excitons in the double layers of kagome lattice by applying circularly polarized irradiation
Sita Kandel, Godfrey Gumbs, Teresa lee +1
We present detailed calculations for several significant properties of the kagome lattice. We employ the Floquet-Magnus perturbation expansion to obtain the energy bands and the co…
Long-living superfluidity of dark excitons in a strip of strained transition metal dichalcogenides double layer
Gabriel Pimenta Martins, Oleg L. Berman, Godfrey Gumbs +1
We have proposed the superfluidity of dipolar excitons in a strip of double-layer transition metal dichalcogenides (TMDCs) heterostructures. We have shown that strain causes a shif…
