Scaling of entanglement entropy and hyperbolic geometry
Hiroaki Matsueda
Various scaling relations of the entanglement entropy are reviewed. Based on the scaling, I would like to point out similarity of mathematical formulation among recent topics in wi…

Entanglement Entropy and Entanglement Spectrum for Two-Dimensional Classical Spin Configuration
Hiroaki Matsueda
In quantum spin chains at criticality, two types of scaling for the entanglement entropy exist: one comes from conformal field theory (CFT), and the other is for entanglement suppo…

Renormalization Group and Curved Spacetime
Hiroaki Matsueda
We examine the role of curved geometry on renormalization group by means of image compression based on the singular value decomposition. By calculating course-grained images and th…
