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…
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…
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…
Fractionalized Fermi liquids and the cuprate phase diagram
Pietro M. Bonetti, Maine Christos, Alexander Nikolaenko +2
We review a theoretical framework for the cuprate superconductors, rooted in a fractionalized Fermi liquid (FL*) description of the intermediate-temperature pseudogap phase at low…
Thermal SU(2) lattice gauge theory for intertwined orders and hole pockets in the cuprates
Harshit Pandey, Maine Christos, Pietro M. Bonetti +3
The cuprate pseudogap phase displays Fermi arc spectral weight in photoemission and scanning tunneling microscopy (STM), while recent magnetotransport observations yield evidence f…
