Excitonic effects in time-dependent density functional theory from zeros of the density response
D. R. Gulevich, Ya. V. Zhumagulov, V. Kozin +1
We show that the analytic structure of the dynamical xc kernels of semiconductors and insulators can be sensed in terms of its poles which mark physically relevant frequencies of t…
Nonlinear spectroscopy of excitonic states in transition metal dichalcogenides
Yaroslav V. Zhumagulov, Vyacheslav D. Neverov, Alexander E. Lukyanov +4
Second-harmonic generation (SHG) is a well-known nonlinear spectroscopy method to probe electronic structure, specifically, in transition metal dichalcogenide (TMDC) monolayers. Th…
Microscopic theory of exciton and trion polaritons in doped monolayers of transition metal dichalcogenides
Y. V. Zhumagulov, S. Chiavazzo, D. R. Gulevich +3
We study a doped transition metal dichalcogenide (TMDC) monolayer in an optical microcavity. Using the microscopic theory, we simulate spectra of quasiparticles emerging due to the…
Electrostatic control of the trion fine structure in transition metal dichalcogenide monolayers
Yaroslav V. Zhumagulov, Alexei Vagov, Dmitry R. Gulevich +1
Charged excitons (trions) are essential for the optical spectra in low dimensional doped monolayers (ML) of transitional metal dichalcogenides (TMDC). Using a direct diagonalizatio…
Vacuum anomalous Hall effect in gyrotropic cavity
Ilya Tokatly, Dmitry Gulevich, Ivan Iorsh
We consider the ground state of an electron gas embedded in a quantum gyrotropic cavity. We show that the light-matter interaction leads to a nontrivial topology of the many-body e…
Trion induced photoluminescence of a doped MoS2 monolayer
Yaroslav V. Zhumagulov, Alexei Vagov, Paulo E. Faria Junior +2
We demonstrate that the temperature and doping dependencies of the photoluminescence (PL) spectra of a doped MoS2 monolayer have several peculiar characteristics defined by trion r…
