Holographic model of exciton condensation in double monolayer Dirac semimetal
A. Pikalov
In this paper we consider holographic model of exciton condensation in double monolayer Dirac semimetal. Excitons is a bound states of an electron and a hole. Being Bose particles,…
Inhomogeneous states in two dimensional linear sigma model at large N
A. Pikalov
In this note we consider inhomogeneous solutions of two-dimensional linear sigma model in the large limit. These solutions are similar to the ones found recently in two-dimensi…
On instability of ground states in 2D CP(N-1) and O(N) models at large N
A. Gorsky, A. Pikalov, A. Vainshtein
We consider properties of the inhomogeneous solution found recently for \mbox{} model. The solution was interpreted as a soliton. We reevaluate its energy in t…
CP(N) model on regions with boundary
A. Pikalov
In this note we discuss the CP(N) model in large N limit in saddle point approximation on disc and annulus with various combinations of Dirichlet and Neumann boundary conditions. W…
Graphene Bilayer Structures with Superfluid Magnetoexcitons
A. A. Pikalov, D. V. Fil
We study superfluid behavior of a gas of spatially indirect magnetoexcitons with reference to a system of two graphene layers embedded in a multilayer dielectric structure. The sys…
Stationary waves in a superfluid exciton gas in quantum Hall bilayers
A. A. Pikalov, D. V. Fil
Stationary waves in a superfluid magnetoexciton gas in nu = 1 quantum Hall bilayers are considered. The waves are induced by counter-propagating electrical currents that flow in a…
