Entanglement asymmetry in conformal field theory and holography
Francesco Benini, Victor Godet, Amartya Harsh Singh
Entanglement asymmetry is a measure of symmetry breaking in quantum subsystems, inspired by quantum information theory, particularly suited to study out-of-equilibrium states. We s…
Quantum information geometry of driven CFTs
Jan de Boer, Victor Godet, Jani Kastikainen +1
Driven quantum systems exhibit a large variety of interesting and sometimes exotic phenomena. Of particular interest are driven conformal field theories (CFTs) which describe quant…
Holography of information in de Sitter space
Tuneer Chakraborty, Joydeep Chakravarty, Victor Godet +2
We study the natural norm on the space of solutions to the Wheeler-DeWitt equation in an asymptotically de Sitter spacetime. We propose that the norm is obtained by integrating the…
The Hilbert space of de Sitter quantum gravity
Tuneer Chakraborty, Joydeep Chakravarty, Victor Godet +2
We obtain solutions of the Wheeler-DeWitt equation with positive cosmological constant for a closed universe in the large-volume limit. We argue that this space of solutions provid…
Euclidean-to-Lorentzian wormhole transition and gravitational symmetry breaking in the Sachdev-Ye-Kitaev model
Antonio M. García-García, Victor Godet, Can Yin +1
We study a two-site Sachdev-Ye-Kitaev model with complex couplings and a weak inter-site interaction. At low temperatures, the system is dual to a Euclidean wormhole in Jackiw-Teit…
Non-topological logarithmic corrections in minimal gauged supergravity
Marina David, Victor Godet, Zhihan Liu +1
We compute the logarithmic correction to the entropy of asymptotically AdS black holes in minimal gauged supergravity. We show that for extremal black holes the lo…
Holography from the Wheeler-DeWitt equation
Chandramouli Chowdhury, Victor Godet, Olga Papadoulaki +1
In a theory of quantum gravity, states can be represented as wavefunctionals that assign an amplitude to a given configuration of matter fields and the metric on a spatial slice. T…
Half-wormholes in nearly AdS holography
Antonio M. García-García, Victor Godet
We find half-wormhole solutions in Jackiw-Teitelboim gravity by allowing the geometry to end on a spacetime D-brane with specific boundary conditions. This theory also contains a E…
From black holes to baby universes in CGHS gravity
Victor Godet, Charles Marteau
We study gravity, a variant of the matterless Callan-Giddings-Harvey-Strominger model. We show that it describes a universal sector of the near horizon pert…
Euclidean wormhole in the SYK model
Antonio M. García-García, Victor Godet
We study a two-site Sachdev-Ye-Kitaev (SYK) model with complex couplings, and identify a low temperature transition to a gapped phase characterized by a constant in temperature fre…
Quantum hypothesis testing in many-body systems
Jan de Boer, Victor Godet, Jani Kastikainen +1
One of the key tasks in physics is to perform measurements in order to determine the state of a system. Often, measurements are aimed at determining the values of physical paramete…
New boundary conditions for AdS
Victor Godet, Charles Marteau
We describe new boundary conditions for AdS in Jackiw-Teitelboim gravity. The asymptotic symmetry group is enhanced to whose breaking to $\…
Gravitation in flat spacetime from entanglement
Victor Godet, Charles Marteau
We explore holographic entanglement entropy for Minkowski spacetime in three and four dimensions. Under some general assumptions on the putative holographic dual, the entanglement…
Breaking away from the near horizon of extreme Kerr
Alejandra Castro, Victor Godet
We study gravitational perturbations around the near horizon geometry of the (near) extreme Kerr black hole. By considering a consistent truncation for the metric fluctuations, we…
Lessons on Eternal Traversable Wormholes in AdS
Ben Freivogel, Victor Godet, Edward Morvan +2
We attempt to construct eternal traversable wormholes connecting two asymptotically AdS regions by introducing a static coupling between their dual CFTs. We prove that there are no…
Logarithmic Corrections to Black Hole Entropy: the Non-BPS Branch
Alejandra Castro, Victor Godet, Finn Larsen +1
We compute the leading logarithmic correction to black hole entropy on the non-BPS branch of 4D supergravity theories. This branch corresponds to finite temperatur…
The Monster, the Baby Monster and Traces of Singular Moduli
Victor Godet
In this note, we provide evidence for new (super) moonshines relating the Monster and the Baby monster to some weakly holomorphic weight 1/2 modular forms defined by Zagier in his…
