Universal entanglement spectra in critical spin chains
Rex Lundgren, Jonathan Blair, Pontus Laurell +4
We advocate that in critical spin chains, and possibly in a larger class of 1D critical models, a gap in the momentum-space entanglement spectrum separates the universal part of th…
Bulk Entanglement Spectrum in Gapped Spin Ladders
Raul A. Santos, Chao-Ming Jian, Rex Lundgren
We study the bulk entanglement of a series of gapped ground states of spin ladders, representative of the Haldane phase. These ground states of spin ladders generalize the va…
Landau theory of helical Fermi liquids
Rex Lundgren, Joseph Maciejko
Landau's phenomenological theory of Fermi liquids is a fundamental paradigm in many-body physics that has been remarkably successful in explaining the properties of a wide range of…
Electronic Cooling in Weyl and Dirac Semimetals
Rex Lundgren, Gregory A. Fiete
Energy transfer from electrons to phonons is an important consideration in any Weyl or Dirac semimetal based application. In this work, we analytically calculate the cooling power…
