Orbital currents and cheap vortices in underdoped cuprates
TL;DR: In this article, a theory for the underdoped cuprates was developed based on an SU(2) formulation of the t-J model, where the staggered flux state plays a central role as the progenitor of the Neel state at half filling and a close competitor to the d-wave superconductor with small doping.

Electron Correlation Effects on Topological Phases
TL;DR: In this paper, the quantum criticality of the transition to topological Mott insulators from zero-gap semiconductors follows unconventional universality distinct from the Landau-Ginzburg-Wilson scenario.

Charge density variations or stripes in YBa2Cu3O6+y
Jürgen Haase,Charles P. Slichter +1 more
TL;DR: In this article, the authors discuss the NMR data of YBa2Cu3O6+y (y > 0.63) and show that large charge density variations are actually necessary in order to explain the data.
