Superconducting and charge-ordered phases from Dirac quantum spin liquids on the triangular lattice
Andreas Feuerpfeil, Ronny Thomale, Subir Sachdev +1
Triangular-lattice quantum spin-liquid insulators are observed to undergo transitions to superconductivity under pressure or doping, and exhibit enhanced terahertz conductivity whe…
Entanglement entropy of fermions in a strange metal
Santanu Singh, Surajit Bera, Chenyuan Li +2
The subsystem-size dependence of ground-state entanglement entropy and its crossover to thermal entropy as a function of temperature are well understood for one-dimensional (1D) ga…
Meissner Effect and Josephson Radiation in Driven Dissipative Superconductors
Carl Philipp Zelle, Subir Sachdev
Photo-induced superconducting signatures have been observed in several materials at temperatures far above their equilibrium critical temperatures, including magnetic field expulsi…
Lectures on insulating and conducting quantum spin liquids
Subir Sachdev
Two of the iconic phases of the hole-doped cuprate materials are the intermediate temperature pseudogap metal and the lower temperature -wave superconductor. Following the sugge…
Influence of Harris disorder on quantum-critical superconductivity
Serhii Kryhin, Peter Lunts, Aavishkar A. Patel +2
In the Hertz theory, a quantum critical metal is described by the coupling of a Fermi surface to fluctuations of a Landau-damped bosonic field , which may represent either an o…
Yamaji effect in models of underdoped cuprates
Jing-Yu Zhao, Shubhayu Chatterjee, Subir Sachdev +1
Recent angle-dependent magnetoresistance measurements in underdoped cuprates have revealed compelling evidence for small hole pockets in the pseudogap regime, including observation…
