A term first coined by Mott back in 1968 a `pseudogap' is the depletion of the electronic density of states at the Fermi level, and pseudogaps have been observed in many systems. However, since the discovery of the high temperature superconductors (HTSC) in 1986, the central role attributed to the pseudogap in these systems has meant that by many researchers now associate the term pseudogap exclusively with the HTSC phenomenon. Recently, the problem has got a lot of new attention with the… Expand

TLDR
Recent progress is reviewed in understanding the relationship between superconductivity and the pseudogap, the Fermi arc phenomena, and the relationships between charge order and Pseudogap from the perspective of ARPES measurements. Expand
Electronic band structure of optimal superconductors: From cuprates to ferropnictides and back again (Review Article)
While the beginning decade of the high-Tc cuprates era passed under domination of local theories, Abrikosov was one of the few who took seriously the electronic band structure of cuprates, stressingExpand
Spectral functions of Sr2IrO4: theory versus experiment.
TLDR
Recent work in the theoretical description of the spectral function of pure and electron-doped Sr2IrO4 based on a cluster extension of dynamical mean-field theory ('oriented-cluster DMFT') is reviewed and extended and compared to available angle-resolved photoemission data. Expand
Structural analysis of the precursor pseudogap in cuprate superconductors
Abstract We investigate the precursor pseudogap (PP) state that emerges on the lower temperature side of the pseudogap phase in cuprate superconductors based on the characteristic layer structure.Expand
Emergence of pseudogap from short-range spin-correlations in electron-doped cuprates

A tale of two metals: contrasting criticalities in the pnictides and hole-doped cuprates.
TLDR
It is argued that the opening of the normal state pseudogap in cuprates arises from a momentum-dependent breakdown of quasiparticle coherence that sets in at much higher doping levels but which is driven by the proximity to the Mott insulating state at half filling. Expand
Hall number, specific heat and superfluid density of overdoped high-Tc cuprates
Despite often being dismissively described as exhibiting conventional Fermi-liquid-like behaviour, heavily overdoped high-Tc cuprates sport several unexpected features. Thermodynamic propertiesExpand
Influence of pseudo-gap and interlayer coupling on isotope effect in bilayer cuprate superconductors
Abstract The present investigations deal with the study of the isotope effect in bilayer cuprate superconductors. We have considered the BCS-effective Hamiltonian that includes the intra andExpand
Origin of the Fermi arcs in cuprates: a dual role of quasiparticle and pair excitations.
TLDR
Starting from the basic properties of the pairon wavefunction, the corresponding k-space spectral function is derived and explains the variation of the ARPES spectra as a function of temperature and angle up to T *, the onset temperature of pairon formation. Expand
Universal spectral signatures in pnictides and cuprates: the role of quasiparticle-pair coupling.
TLDR
The equations of motion for the quasiparticle operators are derived showing that the DOS 'peak-dip-hump' is caused by the coupling between qu asiparticles and excited pair states, or 'super-quasiparticles', and the renormalized SC gap function becomes energy-dependent and non retarded. Expand
