Variations on a Theme of Krylov
Vijay Balasubramanian, Pawel Caputa, Joan Simón
Spread complexity uses the distribution of support of a time-evolving state in the Krylov basis to quantify dispersal across accessible dimensions of a Hilbert space. Here, we desc…
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…
The Library of Babel
Vijay Balasubramanian, Vishnu Jejjala, Joan Simón
We show that heavy pure states of gravity can appear to be mixed states to almost all probes. Our arguments are made for Schwarzschild black holes using the field theo…
