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…

Spread complexity for the planar limit of holography
Rathindra N. Das, Saskia Demulder, Johanna Erdmenger +1
Complexity is a fundamental characteristic of states within a quantum system. Its use is however mostly limited to bosonic systems, inhibiting its present applicability to supersym…

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…
