The quadratic growth of Krylov spread complexity in the BTZ black hole

Aranya Bhattacharya, Mario Flory, Michal P. Heller +2

The boundary quantity that captures the growth of black-hole interiors quantified by holographic complexity remains unknown beyond 2d dilaton gravity. We provide a critical analysi…

Driven inhomogeneous CFT as a theory in curved space-time

Johanna Erdmenger, Jani Kastikainen, Tim Schuhmann

For two-dimensional conformal field theories driven by evolving background space-time metrics in a closed universe, we present an operator formulation as a driven inhomogeneous CFT…

De Sitter holographic complexity from Krylov complexity in DSSYK

Michal P. Heller, Fabio Ori, Jacopo Papalini +2

We utilize the recent connection between the high energy limit of the double-scaled SYK model and two-dimensional de Sitter solutions of sine dilaton gravity to identify the length…

Krylov spread complexity as holographic complexity beyond JT gravity

Michal P. Heller, Jacopo Papalini, Tim Schuhmann

One of the important open problems in quantum black hole physics is a dual interpretation of holographic complexity proposals. To date the only quantitative match is the equality b…

Towards complexity of primary-deformed Virasoro circuits

Johanna Erdmenger, Jani Kastikainen, Tim Schuhmann

The Fubini-Study metric is a central element of information geometry. We explore the role played by information geometry for determining the circuit complexity of Virasoro circuits…
