Many current descriptions of the pseudogap in underdoped cuprates envision a doping-
dependent transition line T*(p) which descends monotonically toward zero just beyond …

(Ca x Sr 1− x) 3 Rh 4 Sn 13 is a rare system that has been shown to display an interesting
interplay between structural quantum criticality and superconductivity. A putative structural …

Developing strategies to systematically increase the critical current, the threshold current
below which the superconductivity exists, is an important goal of materials science. Here, the …

The effect of stacking faults (SF) on flux pinning and critical current (I c) in rare earth based
coated conductors was investigated. The SF density in YBa 2 Cu 3 O 7− δ (YBCO) films with …

The loss of single-particle coherence going from the superconducting state to the normal
state in underdoped cuprates is a dramatic effect that has yet to be understood. Here, we …

Cuprate superconductors have long been known to exhibit an energy gap that persists high
above the superconducting transition temperature (Tc). Debate has continued now for …

We discuss the physics of the high temperature superconductivity in hole doped copper
oxide ceramics in the pseudogap region. Starting from an effective reduced Hamiltonian …

High-temperature superconducting cuprates are distinguished by an enigmatic pseudogap
which opens near optimal doping where the superconducting transition temperature is …

There are several ways to turn a superconductor into a normal conductor: increase the
temperature, apply a high magnetic field, or run a large current. High-T $ _c $ cuprate …

Ac-susceptibility measurements of the superconducting Bi 2 Sr 2 CaCu 2 O ${} _ {8+\delta} $
single crystal for ${\bf {H}}|| c $-axis are presented. In low frequency measurements the first …
