SC state anomalies in the underdoped regime of high-T sub(c) cuprates as a result of proximity to electronic topological transition

摘要

Based on a microscopical theory developed earlier we study electronic and magnetic properties of high-T sub(c) cuprates in the superconducting (SC) state. An agreement with experiments (angle resolved photoemission spectroscopy, tunneling spectroscopy, inelastic neutron scattering) is remarkable.
