Bose Einstein condensation and ferromagnetism of low density Bose gas of particles with arbitrary spin
V. S. Babichenko, I. Ya. Polishchuk
Properties of the ground state and the spectrum of elementary excitations are investigated for the low density ultracold spinor 3D Bose gas of particles with arbitrary nonzero spin…
Chaotic dynamics in a quantum Fermi-Pasta-Ulam problem
Alexander L. Burin, Andrii O. Maksymov, Ma'ayan Schmidt +1
We investigate the emergence of chaotic dynamics in a quantum Fermi - Pasta - Ulam problem for anharmonic vibrations in atomic chains applying semi-quantitative analysis of resonan…
Guided Modes in the Plane Array of Optical Waveguides
I. Ya. Polishchuk, M. I. Gozman, A. A. Anastasiev +3
It is known that for an isolated dielectric cylinder waveguide there exists the cutoff frequency below which there is no guided mode. It is shown in the paper that the inf…
Quantum Phase Transition of the Electron-Hole Liquid In the Coupled Quantum Wells
V. S. Babichenko, I. Ya. Polishchuk
Many-component electron-hole plasma is considered in the Coupled Quantum Wells (CQW). It is found that the homogeneous state of the plasma is unstable if the carrier density is suf…
The influence of boundary conditions on the form of the optical beam in the array of coupled optical waveguides
V. S. Babichenko, M. I. Gozman, A. I. Guseynov +5
We investigate the optical beam behavior in the periodical array of the coupled optical waveguides with the monotonic change of the refractive index in the transverse direction. We…
Anharmonic Bloch Oscillations in the Optical Waveguide Array
M. I. Gozman, A. I. Guseynov, Yu. M. Kagan +2
The anharmonic Bloch oscillations of a light beam in the array of optical waveguides are considered. The coupling modes model (CMM) with the second order interaction is used to des…
