We review the BCS to Bose–Einstein condensation (BEC) crossover scenario which is
based on the well known crossover generalization of the BCS ground state wavefunction …

In this article we review essential natures of superconductivity in strongly correlated electron
systems (SCES) from a universal point of view. First we summarize experimental results on …

The observation of a large Nernst signal e N in an extended region above the critical
temperature T c in hole-doped cuprates provides evidence that vortex excitations survive …

This article reviews the current status of precursor superconducting phase fluctuations as a
possible mechanism for pseudogap formation in high-temperature superconductors. In …

High-T c cuprates differ from conventional superconductors in three crucial aspects: the
superconducting state descends from a strongly correlated Mott-Hubbard insulator (as …

Within the phase fluctuation model for the pseudogap state of cuprate superconductors we
identify a novel statistical “Berry phase” interaction between the nodal quasiparticles and …

The crossover from weak to strong coupling for a three-dimensional continuum model of
fermions interacting via an attractive contact potential is studied above the superconducting …

Motivated by the strong, low temperature dam** of nodal quasiparticles observed in some
cuprate superconductors, we study quantum phase transitions in dx 2− y 2 superconductors …

The Fermi surface symmetric mass generation (SMG) is an intrinsically interaction-driven
mechanism that opens an excitation gap on the Fermi surface without invoking symmetry …

The possibility of driving phase transitions in low-density condensates through the loss of
phase coherence alone has far-reaching implications for the study of quantum phases of …
