Despite more than two decades of intensive investigations, the true nature of high temperature (high-Tc) superconductivity observed in the cuprates remains elusive to the researchers. In particular, in the so-called ‘underdoped’ region, the overall behavior of superconductivity deviates qualitatively from the standard theoretical description pioneered by Bardeen, Cooper and Schrieffer (BCS). Recently, the importance of phase fluctuation of the superconducting order parameter has gained… Expand

TLDR
A universal homogeneous theory for a Bose metal in which geometric frustration confines the essential quantum coherence to a lower dimension produces a gapless insulator characterized by dissipative flow that vanishes in the low-energy limit. Expand
