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

Although the vast majority of high-T c cuprate superconductors are hole-doped, a small
family of electron-doped compounds exists. Underinvestigated until recently, there has been …

This review describes how topological order associated with the presence of emergent
gauge fields can reconstruct Fermi surfaces of metals, even in the absence of translational …

The origin of the exceptionally strong superconductivity of cuprates remains a subject of
debate after more than two decades of investigation. Here we follow a new lead: The onset …

In a superconductor, the ratio of the carrier density, n, to its effective mass, m*, is a
fundamental property directly reflecting the length scale of the superfluid flow, the London …

The interplay between superconductivity and any other competing order is an essential part
of the long-standing debate on the origin of high-temperature superconductivity in cuprate …

The Hall coefficient RH of the cuprate superconductor YBa 2 Cu 3 O y was measured in
magnetic fields up to 60 T for a hole concentration p from 0.078 to 0.152 in the underdoped …

We show that a random interacting model exhibits solvable non-Fermi-liquid behavior and
exotic pairing behavior. This model, dubbed as the Yukawa-SYK model, describes the …

The origin of pairing in a superconductor resides in the underlying normal state. In the
cuprate high-temperature superconductor YBa2Cu3Oy (YBCO), application of a magnetic …

Near a quantum critical point in a metal, a strong fermion-fermion interaction, mediated by a
soft boson, acts in two different directions: it destroys fermionic coherence and it gives rise to …
