Thermal Hall effect in square-lattice spin liquids: A Schwinger boson mean-field study
Rhine Samajdar, Shubhayu Chatterjee, Subir Sachdev +1
Motivated by recent transport measurements in high- cuprate superconductors in a magnetic field, we study the thermal Hall conductivity in materials with topological order, fo…
Fermi surface reconstruction in electron-doped cuprates without antiferromagnetic long-range order
J. -F. He, C. R. Rotundu, M. S. Scheurer +12
Fermi surface (FS) topology is a fundamental property of metals and superconductors. In electron-doped cuprate Nd2-xCexCuO4 (NCCO), an unexpected FS reconstruction has been observe…
Gauge theory for the cuprates near optimal doping
Subir Sachdev, Harley D. Scammell, Mathias S. Scheurer +1
We describe the phase diagram of a 2+1 dimensional SU(2) gauge theory of fluctuating incommensurate spin density waves for the hole-doped cuprates. Our primary assumption is that a…
Orbital currents in insulating and doped antiferromagnets
Mathias S. Scheurer, Subir Sachdev
We describe square lattice spin liquids which break time-reversal symmetry, while preserving translational symmetry. The states are distinguished by the manner in which they transf…
Triangular antiferromagnetism on the honeycomb lattice of twisted bilayer graphene
Alex Thomson, Shubhayu Chatterjee, Subir Sachdev +1
We present the electronic band structures of states with the same symmetry as the three-sublattice planar antiferromagnetic order of the triangular lattice. Such states can also be…
Identifying topological order through unsupervised machine learning
Joaquin F. Rodriguez-Nieva, Mathias S. Scheurer
The Landau description of phase transitions relies on the identification of a local order parameter that indicates the onset of a symmetry-breaking phase. In contrast, topological…
