Controlling thermoelectric, heat, and energy currents through a quantum dot in sequential and cotunneling Coulomb-blockade regimes
Taha Yasin Ahmed, Nzar Rauf Abdullah, Vidar Gudmundsson
Thermal transport through a Coulomb-blockade quantum dot (QD) coupled to two metallic leads is studied using five different approaches to the master equation in which sequential an…
Unified approach to cyclotron and plasmon resonances in a periodic 2DEG hosting the Hofstadter butterfly
Vidar Gudmundsson, Vram Mughnetsyan, Nzar Rauf Abdullah +3
We present theoretical calculations for the cyclotron resonance and various magnetoplasmon modes of a Coulomb interacting two-dimensional GaAs electron gas (2DEG) modulated as a la…
Theory of nonlinear excitonic response of hybrid organic perovskites in the regime of strong light-matter coupling
A. D. Belogur, D. A. Baghdasaryan, I. V. Iorsh +2
We present a quantitative study of the nonlinear optical response of layered perovskites placed inside planar photonic microcavities in the regime of strong light matter coupling,…
Screening nearest-neighbor interactions in networks of exciton-polariton condensates through spin orbit coupling
Denis Aristov, Helgi Sigurdsson, Pavlos G. Lagoudakis
We study the modification of the spatial coupling parameter between interacting ballistic exciton-polariton condensates in the presence of photonic spin orbit coupling appearing fr…
Thermal generation of droplet soliton in chiral magnet
Vladyslav M. Kuchkin, Pavel F. Bessarab, Nikolai S. Kiselev
Controlled creation of localized magnetic textures beyond conventional -skyrmions is an important problem in the field of magnetism. Here by means of spin dynamics simulations,…
Tunable strongly interacting dipolar excitons in hybrid perovskites
D. A. Baghdasaryan, E. S. Hakobyan, D. B. Hayrapetyan +3
We study theoretically the excitonic nonlinearity in hybrid organic-inorganic Ruddlesden-Popper perovskite thin films. The composite layered structure of these materials allows for…
