Simulations of Dynamical Electronic Vortices in Charge and Spin Density Waves

Autor: Natasha Kirova, Serguei Brazovskii

Publikováno v: Symmetry, Vol 15, Iss 4, p 915 (2023)

Charge and spin density waves are typical symmetry broken states of quasi one-dimensional electronic systems. They demonstrate such common features of all incommensurate electronic crystals as a spectacular non-linear conduction by means of the colle

We present a general scheme to approach the space - time evolution of deformations, currents, and the electric field in charge density waves related to appearance of intrinsic topological defects: dislocations, their loops or pairs, and solitons. We

Dynamical phase transitions and pattern formation induced by a pulse pumping of excitons to a system near a thermodynamic instability

We suggest a phenomenological theory of dynamical phase transitions and the subsequent spaciotemporal evolution induced by a short optical pulse in a system which is already prone to a thermodynamic instability. We address the case of pumping to exci

Cyclotron excitations in pure bilayer graphene: Electron–hole asymmetry and Coulomb interaction

Autor: Natasha Kirova, V.E. Bisti

Publikováno v: Physica B: Condensed Matter. 407:1923-1926

Inter-Landau-level transitions in the bilayer graphene in high perpendicular magnetic field at the filling-factor ν = 0 have been studied. The next-nearest-neighbor transitions, energy difference between dimer and non-dimer sites, and layer asymmetr

Charge density excitations in bilayer graphene in high magnetic field

Publikováno v: JETP Letters. 90:120-123

The charge-density excitations in bilayer graphene at the filling-factor ν Open image in new window 1 at small momenta are considered in the frame of the Hartree-Fock approximation. The presence of small asymmetry of graphene layers is included. The
