Inelastic neutron scattering study of magnetic excitations in SrRuO
M. Braden, Y. Sidis, P. Bourges +4
Magnetic excitations in \srruo ~ have been studied by inelastic neutron scattering. The magnetic fluctuations are dominated by incommensurate peaks related to the Fermi surface nes…
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…
New scenario for high-T_c cuprates: electronic topological transition as a motor for anomalies in the underdoped regime
F. Onufrieva, P. Pfeuty, M. Kiselev
We have discovered a new nontrivial aspect of electronic topological transition (ETT) in a 2D free fermion system on a square lattice. The corresponding exotic quantum critical poi…
