3D Einstein action from 6D Kodaira-Spencer gravity

Johanna Erdmenger, Jonathan Karl, Jani Kastikainen +1

In view of embedding 3D gravity into topological string theory, we show that the dimensional reduction of 6D Kodaira-Spencer gravity on , i.e. the low-energ…

Poles-zeros duality in semi-holographic Mott insulators

Thomas Kögel, Alessio Caddeo, Amelie Pitters +5

Inspired by the poles-zeros duality of Green's functions that appears in transitions into Mott-insulating phases in strongly correlated condensed matter systems, we propose a semi-…

Stringy T-duality on the lattice and the twisted Villain model

Coraline Bacq, Alessio Caddeo, Saskia Demulder +1

We address the question of whether dualities formulated in continuum field theory can be realised exactly at finite lattice spacing, rather than only emerging in the infrared. In t…

Topological Einstein gravity as Kodaira-Spencer gravity

Johanna Erdmenger, Jonathan Karl, Jani Kastikainen +3

As a contribution towards quantizing three-dimensional gravity, we show at the classical level that Euclidean three-dimensional Einstein gravity with a negative cosmological consta…

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…

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…
