Abstract We discuss the physics of the high temperature superconductivity in hole doped copper oxide ceramics in the pseudogap region. Starting from an effective reduced Hamiltonian relevant to the dynamics of holes injected into the copper oxide layers proposed in a previous paper, we determine the superconductive condensate wavefunction. We show that the low-lying elementary condensate excitations are analogous to the rotons in superfluid 4He. We argue that the rotons-like excitations account… 
Specific Heat Of Doped HighT C Cuprate Superconductors Within The Bose-Fermi-Hubbard Model
Studies on superconductivity arising from doping a Mott insulator have become critical in the area of superconductivity. Within the framework of the Bose-Fermi-Hubbard model, we discuss the
Quasiparticle conductance-voltage characteristics for break junctions involving d-wave superconductors: charge-density-wave effects.
It was shown that the large variety of the observed current-voltage characteristics can be interpreted in the framework of the approach and quasiparticle tunnel currents in the ab-plane can be used as an additional mean to detect CDWs competing with superconductivity in cuprates or other layered superconductors.
Break-junction tunneling spectra of Bi2212 superconducting ceramics: Influence of inhomogeneous d-wave-Cooper-pairing and charge-density-wave order parameters
Conductance-voltage characteristics (CVCs) of tunnel break junctions made of Bi2Sr2CaCu2O8+δ crystals were measured. It was demonstrated that the CVCs have a V-shaped inner gap region, similar to t...

We present angle-resolved photoemission spectroscopy (ARPES) studies of the cuprate high-temperature superconductors which elucidate the relation between superconductivity and the pseudogap and
Doping a Mott insulator: Physics of high-temperature superconductivity
This article reviews the physics of high-temperature superconductors from the point of view of the doping of a Mott insulator. The basic electronic structure of cuprates is reviewed, emphasizing the
Scattering and Pairing in Cuprate Superconductors
The origin of the exceptionally strong superconductivity of cuprates remains a subject of debate after more than two decades of investigation. Here we follow a new lead: The onset temperature for
Disappearance of nodal gap across the insulator-superconductor transition in a copper-oxide superconductor.
High-resolution angle-resolved photoemission measurement on heavily underdoped Bi₂Sr₁-xLaxCuO(₆+δ) system reveals a clear insulator-superconductor transition at a critical doping level of ~0.10, which clearly signal a close connection between the nodal gap, antiferromagnetism and superconductivity.
Erratum: Dynamic spin fluctuations and the bag mechanism of high-Tc superconductivity
The spin-bag approach to the high-temperature superconductivity is presented in detail. The general argument that the local supression of the electronic pseudogap lead to an attractive interaction of
Quasiparticle mass enhancement approaching optimal doping in a high-Tc superconductor
Using magnetic fields exceeding 90 tesla to access the underlying metallic state of the cuprate YBa2Cu3O6+δ over a wide range of doping, magnetic quantum oscillations reveal a strong enhancement of the quasiparticle effective mass toward optimal doping.

We survey recent experimental results including quantum oscillations and complementary measurements probing the electronic structure of underdoped cuprates, and theoretical proposals to explain them.
Bounding the pseudogap with a line of phase transitions in YBa2Cu3O6+δ
It is reported that the pseudogap in YBa2Cu3O6+δ is a distinct phase, bounded by a line of phase transitions that terminates at zero temperature inside the superconducting dome.
