The Density of Surface States in Weyl Semimetals
Alexander P. Protogenov, Valery A. Verbus, Evgueni V. Chulkov
Weyl semimetal is a three-dimensional material with a conical spectrum near an even number of point nodes, where two bands touch each other. Here we study spectral properties of su…
Topological phase states of the SU(3) QCD
Alexander P. Protogenov, Evgueni V. Chulkov, Jeffrey C. Y. Teo
We consider the topologically nontrivial phase states and the corresponding topological defects in the SU(3) d-dimensional quantum chromodynamics (QCD). The homotopy groups for top…
Nonlocal Edge State Transport in Topological Insulators
Alexander P. Protogenov, Evgueni V. Chulkov, Valery A. Verbus
We use the N-terminal scheme for studying the edge state transportin in two-dimensional topological insulators. We find the universal nonlocal response in the ballistic transport a…
Topologically ordered phase states: from knots and braids to quantum dimers
Luigi Martina, Alexander Protogenov, Valery Verbus
We consider universal statistical properties of systems that are characterized by phase states with macroscopic degeneracy of the ground state. A possible topological order in such…
Energy Bounds of Linked Vortex States
A. P. Protogenov, V. A. Verbus
Energy bounds of knotted and linked vortex states in a charged two-component system are considered. It is shown that a set of local minima of free energy contains new classes of un…
Equations and Integrals of Motion in Discrete Integrable Algebra Models
A. P. Protogenov, V. A. Verbus
We study integrals of motion for Hirota bilinear difference equation that is satisfied by the eigenvalues of the transfer-matrix. The combinations of the eigenvalues of the transfe…
