Abrupt onset of a second energy gap at the superconducting transition of underdoped Bi2212
TL;DR: In this article, the authors reported the discovery of an energy gap in underdoped Bi2Sr2CaCu2O8+delta in the momentum space region overlooked in previous measurements.

Fragile superconductivity in the presence of weakly disordered charge density waves
Yue Yu,Steven A. Kivelson +1 more
TL;DR: In this paper, the authors demonstrate the generic occurrence of a ''fragile'' superconducting phase at low temperatures and high fields in the presence of weak disorder, showing that the SC order is largely concentrated in the vicinity of dilute dislocations in the CDW order.

Spin-charge gauge approach to the pseudogap phase of high-T-c cuprates: Theory versus experiments
TL;DR: In this paper, a spin [SU(2)] and charge [U(1)] Chern-Simons gauge field theory, applied to the t-J model, is developed to describe the metal-insulator crossover in underdoped, nonsuperconducting cuprates as temperature decreases and a similar crossover in superconducting crates when a strong magnetic field suppresses superconductivity.

Spinon-holon binding in t − J model
TL;DR: In this article, the consequences of spinon-holon binding in the slave-boson approach to the weak-coupling limit were discussed, where the quasiparticles in the superconducting state were coupled to external electromagnetic field with a coupling constant of order of order (x}^{\ensuremath{\gamma}∕2}\phantom{\rule{0.3em}{0ex}}(x=\text{hole concentration})$, where
