Unifying Dirac Spin Liquids on Square and Shastry-Sutherland Lattices via Fermionic Deconfined Criticality
Andreas Feuerpfeil, Leyna Shackleton, Atanu Maity +3
We present a fermionic gauge theory for deconfined quantum criticality on the Shastry-Sutherland lattice and reveal its shared low-energy field-theoretic structure with the square…

Thermopower across Fermi-volume-changing quantum phase transitions without translational symmetry breaking
Peter Lunts, Aavishkar A. Patel, Subir Sachdev
We describe the evolution of low-temperature thermopower across Fermi-volume-changing quantum phase transitions in Kondo lattice models without translational symmetry breaking. Thi…

Thermal Hall response of an abelian chiral spin liquid at finite temperatures
Avijit Maity, Haoyu Guo, Subir Sachdev +1
Thermal Hall transport has emerged as a valuable tool for probing the fractionalized excitations in chiral quantum spin liquids. Observing quantized thermal Hall response, expected…
