Composite quasiparticles and the "hidden" quantum critical point in the topological transition scenario of high-Tc cuprates
Abstract
The quantum interference effects due to the Aharonov-Bohm-type phase factors are studied in the layered t-t'-t-U-J strongly correlated system relevant for cuprates. Casting Coulomb interaction in terms of composite-fermions via the flux attachment facility, we argue that U(1) compact group instanton events labeled by a topological winding number are essential configurations of the phase field dual to the charge. The impact of these topological excitations is calculated for the phase diagram, which displays the "hidden" quantum critical point.
