Continuous transitions between composite Fermi liquid and Landau Fermi liquid: a route to fractionalized Mott insulators
Maissam Barkeshli, John McGreevy
One of the most successful theories of a non-Fermi liquid metallic state is the composite Fermi liquid (CFL) theory of the half-filled Landau level. In this paper, we study continu…
Quantum spin liquids and the metal-insulator transition in doped semiconductors
Andrew C. Potter, Maissam Barkeshli, John McGreevy +1
We describe a new possible route to the metal-insulator transition in doped semiconductors such as Si:P or Si:B. We explore the possibility that the loss of metallic transport occu…
A quantum electron star
Andrea Allais, John McGreevy, S. Josephine Suh
We construct and probe a holographic description of state of matter which results from coupling a Fermi liquid to a relativistic conformal field theory (CFT). The bulk solution is…
A continuous transition between fractional quantum Hall and superfluid states
Maissam Barkeshli, John McGreevy
We develop a theory of a direct, continuous quantum phase transition between a bosonic Laughlin fractional quantum Hall (FQH) state and a superfluid, generalizing the Mott insulato…
