The electronic phase diagrams of many highly correlated systems, and, in particular, the
cuprate high temperature superconductors, are complex, with many different phases …

This article gives an overview of both theoretical and experimental developments
concerning states with lattice symmetry breaking in the cuprate high-temperature …

We present a renormalization-group theory for the onset of Ising-nematic order in a Fermi
liquid in two spatial dimensions. This is a quantum phase transition, driven by electron …

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 …

Recent transport experiments in the original cuprate high temperature superconductor, La
2− x Ba x CuO 4, have revealed a remarkable sequence of transitions and crossovers that …

We define a distinct phase of matter, a pair-density wave (PDW), in which the
superconducting order parameter ϕ (r ⃗, r ⃗′) varies periodically as a function of position …

We show that time-reversal invariant superconductors in d= 2 (d= 3) dimensions can support
topologically stable Fermi points (lines), characterized by an integer topological charge …

Electromagnetic responses in superconductors provide valuable information on the pairing
symmetry as well as physical quantities such as the superfluid density. However, at the …

A central issue in high-T c superconductivity is the nature of the normal-state gap
(pseudogap) in the underdoped regime and its relationship with superconductivity. Despite …

Many seemingly contradictory experimental findings concerning the superconducting state
in Sr 2 RuO 4 can be accounted for on the basis of a conjectured accidental degeneracy …
