Effects of proximity to an electronic topological transition on normal state transport properties of the high-Tc superconductors
G. G. N. Angilella, R. Pucci, A. A. Varlamov +1
Within the time dependent Ginzburg-Landau theory, the effects of the superconducting fluctuations on the transport properties above the critical temperature are characterized by a…
Various ordered states in a 2D interacting electron system close to an electronic topological transition
F. Bouis, M. N. Kiselev, F. Onufrieva +1
We consider a 2D electron system on a square lattice with hopping beyond nearest neighbors. The existence of the quantum critical point associated with an electronic topological tr…
SC state in the underdoped high-T_c cuprates as a quantum spin liquid. A microscopic theory
F. Onufrieva, P. Pfeuty
We have discovered a new example of quantum spin liquid which is a superconducting (SC) phase in 2D electron system close to electronic topological transition. As a quantum spin li…
Normal state pseudogap and (π,0) feature in the underdoped high-T_c cuprates. A microscopical theory
F. Onufrieva, P. Pfeuty
We show that a simple 2D electron system on a square lattice with hoping between more than nearest neighbors exhibits in the presence of electron spin exchange interaction properti…
Electronic topological transition in 2D electron system on a square lattice and the line T^*(δ) in the underdoped regime of high - T_c cuprates
F. Onufrieva, P. Pfeuty
It is shown that a 2D system of free fermions on a square lattice with hoping between more than nearest neighbours undergoes a fundamental electronic topological transition (ETT) a…
Some aspects of electronic topological transition in 2D system on a square lattice. Excitonic ordered states
M. Kiselev, F. Bouis, F. Onufrieva +1
We study the ordered "excitonic" states which develop around the quantum critical point (QCP) associated with the electronic topological transition (ETT) in a 2D electron system on…
