Carrier-induced ferromagnetism in 2D magnetically-doped semiconductor structures
V. A. Stephanovich, E. V. Kirichenko, G. Engel +2
We show theoretically that the magnetic ions, randomly distributed in a two-dimensional (2D) semiconductor system, can generate a ferromagnetic long-range order via the RKKY intera…
Chaotic cyclotron and Hall trajectories due to spin-orbit coupling
E. V. Kirichenko, V. A. Stephanovich, E. Ya. Sherman
We demonstrate that the synergistic effect of a gauge field, Rashba spin-orbit coupling (SOC), and Zeeman splitting can generate chaotic cyclotron and Hall trajectories of particle…
Lévy flights confinement in a parabolic potential and fractional quantum oscillator
E. V. Kirichenko, V. A. Stephanovich
We study Lévy flights confined in a parabolic potential. This has to do with a fractional generalization of ordinary quantum-mechanical oscillator problem. To solve the spectral pr…
Revealing quantum spin liquid in the herbertsmithite
V. R. Shaginyan, M. Ya. Amusia, J. W. Clark +5
Based on experimental data and our theoretical analysis, we provide a strategy for unambiguous establishing of gapless quantum spin liquid state (QSL) in herbertsmithite and other…
New state of matter: heavy-fermion systems, quantum spin liquids, quasicrystals, cold gases, and high temperature superconductors
V. R. Shaginyan, V. A. Stephanovich, A. Z. Msezane +6
We report on a new state of matter manifested by strongly correlated Fermi systems including various heavy-fermion (HF) metals, two-dimensional quantum liquids such as f…
Lévy flights in the infinite potential well as the hypersingular Fredholm problem
Elena V. Kirichenko, Piotr Garbaczewski, Vladimir Stephanovich +1
We study Lévy flights {with arbitrary index } inside a potential well of infinite depth. Such problem appears in many physical systems ranging from stochastic interface…
