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…
Polaronic correlations from optimized ancilla wave functions for the Fermi-Hubbard model
Tobias Müller, Ronny Thomale, Subir Sachdev +1
We employ a family of ancilla qubit variational wave-functions [Zhang and Sachdev, Phys. Rev. Res. 2, 023172 (2020)] to describe the polaronic correlations in the pseudo-gap metal…
Vortex structure in a -wave superconductor obtained by a confinement transition from the pseudogap metal
Jia-Xin Zhang, Subir Sachdev
We compute the structure of flux vortices in a d-wave superconductor which emerges from a higher temperature pseudogap metal. Such a transition is described by a continuum…
Strange metal and superconductor in the two-dimensional Yukawa-Sachdev-Ye-Kitaev model
Chenyuan Li, Davide Valentinis, Aavishkar A. Patel +4
The two-dimensional Yukawa-Sachdev-Ye-Kitaev (2d-YSYK) model provides a universal theory of quantum phase transitions in metals in the presence of quenched random spatial fluctuati…
Quantum oscillations in the hole-doped cuprates and the confinement of spinons
Pietro M. Bonetti, Maine Christos, Subir Sachdev
A long standing problem in the study of the under-hole-doped cuprates has been the description of the Fermi surfaces underlying the high magnetic field quantum oscillations, and th…
Strong non-linear response of strange metals
Serhii Kryhin, Subir Sachdev, Pavel A. Volkov
We show that nonlinear transport responses in strange metals are strong, larger by a factor of than in Fermi liquids. Within the two-dimensional Yukawa-Sachdev-Ye-Kitaev mo…
Deconfined quantum criticality of nodal -wave superconductivity, Néel order, and charge order on the square lattice at half-filling
Maine Christos, Henry Shackleton, Subir Sachdev +1
We consider a SU(2) lattice gauge theory on the square lattice, with a single fundamental complex fermion and a single fundamental complex boson on each lattice site. Projective sy…
