Thermal Pseudo-Entropy
Pawel Caputa, Bowen Chen, Tadashi Takayanagi +1
In this work, we develop a generalisation of the thermal entropy to complex inverse temperatures, which we call the thermal pseudo-entropy. We show that this quantity represents th…
Spread Complexity Rate as Proper Momentum
Pawel Caputa, Bowen Chen, Ross W. McDonald +2
We demonstrate a precise relation between the rate of complexity of quantum states excited by local operators in two-dimensional conformal field theories and the radial momentum of…
Musings on SVD and pseudo entanglement entropies
Pawel Caputa, Souradeep Purkayastha, Abhigyan Saha +1
Pseudo-entropy and SVD entropy are generalizations of the entanglement entropy that involve post-selection. In this work we analyze their properties as measures on the spaces of qu…
