2 days ago · Conformal field theory (CFT) has played a pivotal role in understanding the topological phases of matter represented by many fractional quantum Hall effect (FQHE) trial wave functions. Previous papers have shown how the topological properties of a trial wave function expressible as a CFT correlation function can be related to properties of the corresponding CFT, assuming a field-theoretic ...

5 days ago · In this paper, we explore the concept of pseudo Rényi entropy within the context of quantum field theories (QFTs). The transition matrix is constructed by applying operators situated in different regions to the vacuum state. Specifically, when the operators are positioned in the left and right Rindler wedges respectively, we discover that the logarithmic term of the pseudo Rényi entropy is ...
