Scissors modes in generalized Gross-Pitaevskii equations
Oleksandr V. Marchukov, Neelam Shukla, Bastien Humbert +3
We investigate scissors modes in nonlinear systems with arbitrary power-law dependence of the nonlinear term. Through analytical derivation, we establish a general expression demon…
Shape of a sound wave in a weakly-perturbed Bose gas
Oleksandr V. Marchukov, Artem G. Volosniev
We employ the Gross-Pitaevskii equation to study acoustic emission generated in a uniform Bose gas by a static impurity. The impurity excites a sound-wave packet, which propagates…
Energy levels repulsion by spin-orbit coupling in two-dimensional Rydberg excitons
V. A. Stephanovich, E. Ya. Sherman, N. T. Zinner +1
We study the effects of Rashba spin-orbit coupling on two-dimensional Rydberg exciton systems. Using analytical and numerical arguments we demonstrate that this coupling considerab…
Computation of local exchange coefficients in strongly interacting one-dimensional few-body systems: local density approximation and exact results
O. V. Marchukov, E. H. Eriksen, J. M. Midtgaard +4
One-dimensional multi-component Fermi or Bose systems with strong zero-range interactions can be described in terms of local exchange coefficients and mapping the problem into a sp…
Repulsively interacting fermions in a two-dimensional deformed trap with spin-orbit coupling
O. V. Marchukov, D. V. Fedorov, A. S. Jensen +2
We investigate a two-dimensional system of with two values of the internal (spin) degree of freedom. It is confined by a deformed harmonic trap and subject to a Zeeman field, Rashb…
Statistical properties of spectra in harmonically trapped spin-orbit coupled systems
O. V. Marchukov, A. G. Volosniev, D. V. Fedorov +2
We compute single-particle energy spectra for a one-body hamiltonian consisting of a two-dimensional deformed harmonic oscillator potential, the Rashba spin-orbit coupling and the…
Spin-Orbit Coupling in Deformed Harmonic Traps
Oleksandr V. Marchukov, Artem G. Volosniev, Dmitri V. Fedorov +2
We consider a two-dimensional system of harmonically trapped particles with pseudo-spin- degree of freedom. This degree of freedom is coupled to the particle's momentu…
Spectral Gaps of Spin-orbit Coupled Particles in Deformed Traps
O. V. Marchukov, A. G. Volosniev, D. V. Fedorov +2
We consider a spin-orbit coupled system of particles in an external trap that is represented by a deformed harmonic oscillator potential. The spin-orbit interaction is a Rashba int…
