The influence of nontrivial topology on the vacuums of lattice gauge theories and spin systems; Approaches to the study of critical phenomena in lattice field theory
Scientific seminar of the department: Wednesday, November 15, 16:15, K-418 The influence of nontrivial topology on the vacuums of lattice gauge theories and spin systems Alexey Tanashkin Pacific Quantum Center of the Far Eastern Federal University
The report examines the influence of various methods of inducing nontrivial topology on the vacuums of lattice gauge theories and the ground states of spin systems using several examples. The restructuring of the vacuum of (Abelian) compact electrodynamics and (non-Abelian) Yang-Mills theory with a gauge group SU(3) at zero temperature in 3+1 dimensions in the presence of perfectly conducting parallel plates limiting one of the dimensions of the theory is described.
