Universal corner entanglement of Dirac fermions and gapless bosons from the continuum to the lattice
Johannes Helmes, Lauren E. Hayward Sierens, Anushya Chandran +2
A quantum critical (QC) fluid exhibits universal subleading corrections to the area law of its entanglement entropies. In two dimensions when the partition involves a corner of ang…

A Rényi entropy perspective on topological order in classical toric code models
Johannes Helmes, Jean-Marie Stéphan, Simon Trebst
Concepts of information theory are increasingly used to characterize collective phenomena in condensed matter systems, such as the use of entanglement entropies to identify emergen…
