Entanglement flow in the Kane-Fisher quantum impurity problem
Chunyu Tan, Yuxiao Hang, Stephan Haas +1
The problem of a local impurity in a Luttinger liquid, just like the anisotropic Kondo problem (of which it is technically a cousin), describes many different physical systems. As…

Parity effects and universal terms of O(1) in the entanglement near a boundary
Henning Schlömer, Chunyu Tan, Stephan Haas +1
In the presence of boundaries, the entanglement entropy in lattice models is known to exhibit oscillations with the (parity of the) length of the subsystem, which however decay to…

Detection of Topology via Entanglement Oscillations
Chunyu Tan, Hubert Saleur, Stephan Haas
We introduce a characterization of topological order based on bulk oscillations of the entanglement entropy and the definition of an `entanglement gap', showing that it is generall…
