A wide range of materials, like d-wave superconductors, graphene, and topological
insulators, share a fundamental similarity: their low-energy fermionic excitations behave as …

The structures, the phase diagrams, and the appearance of a neutron resonance signaling
an unconventional superconducting state provide phenomenological evidence relating the …

Recently superconductivity was discovered in the Kagome metal AV3Sb5 (A= K, Rb, and
Cs), which has an ideal Kagome lattice of vanadium. These V-based superconductors also …

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 …

This article discusses fluctuating order in a quantum disordered phase proximate to a
quantum critical point, with particular emphasis on fluctuating stripe order. Optimal strategies …

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 …

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 …

We review recent experimental and theoretical results on the interaction between single-
particle excitations and collective spin excitations in the superconducting state of high-Tc …

The doping dependence of nanoscale electronic structure in superconducting Bi 2 Sr 2 Ca
Cu 2 O 8+ δ is studied by scanning tunneling microscopy. At all dopings, the low energy …

We used angle-resolved photoemission spectroscopy applied to deeply underdoped
cuprate superconductors Bi2Sr2Ca (1–x) Y x Cu2O8 (Bi2212) to reveal the presence of two …
