Phenomenological phase-fluctuation model for the underdoped cuprates
… model for the pseudogap regime of the underdoped cuprates was discussed. The key idea of the phase-fluctuation scenario in the high-T_c superconductors is the notion that the pseudogap observed in a wide variety of experiments arises from phase fluctuations of the superconducting gap. …

Topics in the Theory of High-Temperature Superconductors
… the cuprate materials. In particular, strongly underdoped cuprates exhibit antiferromagnetic order, whereas moderately underdoped cuprate superconductors exhibit a pseudogap in the excitation spectrum above the superconducting transition temperature. It is likely that an understanding of the …

Aspects of spin-charge separation in high Tc cuprates
High Tc, cuprates have a number of features that are anomalous from the point of view of the conventional theory of metals, i.e. the Fermi liquid theory. These include the high Tc itself, the linear resistivity in optimally doped cuprates, the "spin gap" phenomena, and antiferromagnetic …

High magnetic field study of strongly correlated electron systems
… temperature superconductors - iron arsenides and underdoped cuprates - as well as high field torque magnetometry and magnetisation measurements on the Kondo insulator samarium hexaboride. Shubnikov-de Haas oscillations observed in the former further our understanding of the nature of the normal …

Electronic properties of doped Mott insulators and high temperature superconductors
High-temperature superconducting cuprates, which are the quintessential example of a strongly correlated system and the most extensively studied materials after semiconductors, spurred the development in the fields of material science and experimental and theoretical physics. As first noted by …

Phases and phase transitions of strongly correlated electron systems
… of this is normal state of optimally doped cuprates; the quasiparticle peaks on the nominal fermi surface do not appear uniformly. We try to track such phenomena in heavy fermion systems, which are correlated fermi liquids. In these systems, a lattice of localized electrons in f or d …
