Topological Luttinger Liquids from Decorated Domain Walls
Daniel E Parker, Thomas Scaffidi, Romain Vasseur
We introduce a systematic construction of a gapless symmetry protected topological phase in one dimension by "decorating" the domain walls of Luttinger liquids. The resulting stron…
Gapless Symmetry Protected Topological Order
Thomas Scaffidi, Daniel E. Parker, Romain Vasseur
We introduce exactly solvable gapless quantum systems in dimensions that support symmetry protected topological (SPT) edge modes. Our construction leads to long-range entangled…
Entanglement Entropy in Excited States of the Quantum Lifshitz Model
Daniel E. Parker, Romain Vasseur, Joel E. Moore
We investigate the entanglement properties of an infinite class of excited states in the quantum Lifshitz model (QLM). The presence of a conformal quantum critical point in the QLM…
