Quantum oscillations in the hole-doped cuprates and the confinement of spinons

PM Bonetti, M Christos, S Sachdev - … of the National Academy of Sciences, 2024 - pnas.org
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 …

Deconfined quantum criticality of nodal -wave superconductivity, Néel order, and charge order on the square lattice at half-filling

M Christos, H Shackleton, S Sachdev, ZX Luo - Physical Review Research, 2024 - APS
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 …

Vortex structure in a -wave superconductor obtained by a confinement transition from the pseudogap metal

JX Zhang, S Sachdev - Physical Review B, 2024 - APS
We compute the structure of flux h/(2 e) vortices in ad-wave superconductor, which emerges
from a higher-temperature pseudogap metal. Such a transition is described by a continuum …
