Superconductivity in strongly repulsive fermions: the role of kinetic-energy frustration
L. Isaev, G. Ortiz, C. D. Batista
We discuss a physical mechanism of a non-BCS nature which can stabilize a superconducting state in a {\it strongly repulsive} electronic system. By considering the two-dimensional…

Structure of Multi-Meron Knot Action
L. S. Isaev, A. P. Protogenov
We consider the structure of multi-meron knot action in the Yang-Mills theory and in the CP^1 Ginzburg-Landau model. Self-dual equations have been obtained without identifying orie…
