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…
