Quantum chaos on a critical Fermi surface
Aavishkar A. Patel, Subir Sachdev
We compute parameters characterizing many-body quantum chaos for a critical Fermi surface without quasiparticle excitations. We examine a theory of species of fermions at non-z…
Two dimensional spin liquids with topological order in an array of quantum wires
Aavishkar A. Patel, Debanjan Chowdhury
Insulating spin liquids are a phase of matter with bulk anyonic quasiparticle excitations and ground state degeneracies on manifolds with non-trivial topology. In th…
Shear viscosity at the Ising-nematic quantum critical point in two dimensional metals
Andreas Eberlein, Aavishkar A. Patel, Subir Sachdev
In an isotropic strongly interacting quantum liquid without quasiparticles, general scaling arguments imply that the dimensionless ratio , where is the shea…
Light induced enhancement of superconductivity via melting of competing bond-density wave order in underdoped cuprates
Aavishkar A. Patel, Andreas Eberlein
We develop a theory for light-induced superconductivity in underdoped cuprates in which the competing bond-density wave order is suppressed by driving phonons with light. Close to…
Confinement transition to density wave order in metallic doped spin liquids
Aavishkar A. Patel, Debanjan Chowdhury, Andrea Allais +1
Insulating quantum spin liquids can undergo a confinement transition to a valence bond solid state via the condensation of topological excitations of the associated gauge theory. W…
