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…

Cornering gapless quantum states via their torus entanglement
William Witczak-Krempa, Lauren E. Hayward Sierens, Roger G. Melko
The entanglement entropy (EE) has emerged as an important window into the structure of complex quantum states of matter. We analyze the universal part of the EE for gapless systems…
