Strength of the Hubbard potential and its modification by breathing distortion in
Alexander E. Lukyanov, Ivan A. Kovalev, Vyacheslav D. Neverov +3
compound is known as an archetype example of a three-dimensional Holstein model with the realization of the charge density wave state at half-filling and the sup…
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…
Laser-induced ultrafast insulator-metal transition in
Alexander E. Lukyanov, Vyacheslav D. Neverov, Yaroslav V. Zhumagulov +3
We investigate ultra-fast coherent quantum dynamics of undoped driven by a strong laser pulse. Our calculations demonstrate that in a wide range of radiation fre…
Calculation of density of states of transition metals: from bulk sample to nanocluster
Petr V. Borisyuk, Oleg S. Vasiliev, Yaroslav V. Zhumagulov +4
The technique is presented of restoring the electronic density of states of the valence band from data of X-ray photoelectron spectroscopy. The originality of the technique consist…
Momentum distribution and non-Fermi liquid behaviour in low-doped two-orbital model: finite-size cluster quantum Monte Carlo approach
Vladimir A. Kashurnikov, Andrey V. Krasavin, Yaroslav V. Zhumagulov
The two-dimensional two-orbital Hubbard model is studied with the use of finite-size cluster worldline quantum Monte Carlo algorithm. This model is widely used for simulation of th…
