The spectral energy gap is an important signature that defines states of quantum matter:
insulators, density waves and superconductors have very different gap structures. The …

The last decade witnessed significant progress in angle-resolved photoemission
spectroscopy (ARPES) and its applications. Today, ARPES experiments with 2-meV energy …

In high-temperature cuprate superconductors, the superconducting transition temperature (T
c) depends on the number of CuO2 planes in the structural unit and the maximum T c is …

Ultracold Fermi gases with tunable interactions provide a test bed for exploring the many-
body physics of strongly interacting quantum systems,,,. Over the past decade, experiments …

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 …

The parent compounds of the copper oxide high-transition-temperature (high-T c)
superconductors are unusual insulators (so-called Mott insulators). Superconductivity arises …

One of the first theoretical proposals for understanding high-temperature superconductivity
in the cuprates was Anderson's RVB theory using a Gutzwiller projected BCS wavefunction …

Understanding the electron pairing in hole-doped cuprate superconductors has been a
challenge, in particular because the “normal” state from which it evolves is unprecedented …

One of the keys to the high-temperature superconductivity puzzle is the identification of the
energy scales associated with the emergence of a coherent condensate of superconducting …

The electronic structure of simple crystalline solids can be completely described in terms
either of local quantum states in real space (r-space), or of wave-like states defined in …
