The study of entanglement has gained prominence in recent years due to the advent
of fields such as Quantum Optics and Quantum Information Theory — advances that have harnessed such counter-intuitive quantum phenomena ...

Studying finite cutoff CFT holds much importance in both Condensed Matter Physics and
AdS/CFT conjecture. As lattice systems always have an inherent scale, it is important to
devise a theory that will be valid for all ...
