Exponentiation of higher-point and higher-genus Virasoro conformal blocks in the semiclassical limit
Marius Gerbershagen, Jakob Hollweck
A long-standing conjecture claims that Virasoro conformal blocks exponentiate in the semiclassical limit with finite. However, this has been proven only for fo…
Area terms and entanglement entropy in the string theory
Ben Craps, Marius Gerbershagen, Maxim Pavlov +1
We study entanglement entropy in the low-energy effective field theory of two-dimensional string theory as well as in the singlet sector of the dual matrix quantum mechanics.…
Holographic dual of Bures metric and subregion complexity
Marius Gerbershagen, Juan Hernandez, Mikhail Khramtsov +1
Within the AdS/CFT correspondence, computational complexity for reduced density matrices of holographic conformal field theories has been conjectured to be related to certain geome…
Bulk quantum corrections to entwinement
Marius Gerbershagen, Dongming He
We determine corrections to a notion of generalized entanglement entropy known as entwinement dual to the length of a winding geodesic in asymptotically AdS geometries. W…
From Complexity Geometry to Holographic Spacetime
Johanna Erdmenger, Marius Gerbershagen, Michal P. Heller +1
An important conjecture within the AdS/CFT correspondence relates holographic spacetime to the quantum computational complexity of the dual quantum field theory. However, the quant…
Exact Gravity Duals for Simple Quantum Circuits
Johanna Erdmenger, Mario Flory, Marius Gerbershagen +2
Holographic complexity proposals have sparked interest in quantifying the cost of state preparation in quantum field theories and its possible dual gravitational manifestations. Th…
Illuminating entanglement shadows of BTZ black holes by a generalized entanglement measure
Marius Gerbershagen
We define a generalized entanglement measure in the context of the AdS/CFT correspondence. Compared to the ordinary entanglement entropy for a spatial subregion dual to the area of…
Monodromy methods for torus conformal blocks and entanglement entropy at large central charge
Marius Gerbershagen
We compute the entanglement entropy in a two dimensional conformal field theory at finite size and finite temperature in the large central charge limit via the replica trick. We fi…
Complexity measures from geometric actions on Virasoro and Kac-Moody orbits
Johanna Erdmenger, Marius Gerbershagen, Anna-Lena Weigel
We further advance the study of the notion of computational complexity for 2d CFTs based on a gate set built out of conformal symmetry transformations. Previously, it was shown tha…
Entwinement as a possible alternative to complexity
Johanna Erdmenger, Marius Gerbershagen
Unlike the standard entanglement entropy considered in the holographic context, entwinement measures entanglement between degrees of freedom that are not associated to a spatial su…
Holographic Subregion Complexity from Kinematic Space
Raimond Abt, Johanna Erdmenger, Marius Gerbershagen +2
We consider the computation of volumes contained in a spatial slice of AdS in terms of observables in a dual CFT. Our main tool is kinematic space, defined either from the bulk…
