Imaging stress and magnetism at high pressures using a nanoscale quantum sensor
S. Hsieh, P. Bhattacharyya, C. Zu +15
Pressure alters the physical, chemical and electronic properties of matter. The development of the diamond anvil cell (DAC) enables tabletop experiments to investigate a diverse la…
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…
Diagnosing phases of magnetic insulators via noise magnetometry with spin qubits
Shubhayu Chatterjee, Joaquin F. Rodriguez-Nieva, Eugene Demler
Two-dimensional magnetic insulators exhibit a plethora of competing ground states, such as ordered (anti)ferromagnets, exotic quantum spin liquid states with topological order and…
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…
