Dressed States Call for Logarithmic Asymptotic Symmetries
Jorrit Bosma, Jeremy A. Mann, Charles Marteau +2
Inspired by Wigner's classification of elementary particles as irreducible unitary representations of a spacetime symmetry group, we ask what group can give rise in this way to the…
Bringing together two paradigms of non-equilibrium: Fragile versus robust aging in driven glassy systems
Diego Tapias, Charles Marteau, Fabián Aguirre-López +1
There are two key paradigms for non-equilibrium dynamics: on the one hand, aging towards an equilibrium state that cannot be reached on reasonable timescales; on the other, externa…
Ground State Preparation via Qubitization
Charles Marteau
We describe a protocol for preparing the ground state of a Hamiltonian on a quantum computer. This is done by designing a quantum algorithm that implements the imaginary time e…
Symmetries and spectral statistics in chaotic conformal field theories
Felix M. Haehl, Charles Marteau, Wyatt Reeves +1
We discuss spectral correlations in coarse-grained chaotic two-dimensional CFTs with large central charge. We study a partition function describing the dense part of the spectrum o…
Holographic Lorentz and Carroll Frames
Andrea Campoleoni, Luca Ciambelli, Arnaud Delfante +3
Relaxing the Bondi gauge, the solution space of three-dimensional gravity in the metric formulation has been shown to contain an additional free function that promotes the boundary…
A Matrix Model for Flat Space Quantum Gravity
Arjun Kar, Lampros Lamprou, Charles Marteau +1
We take a step towards the non-perturbative description of a two-dimensional dilaton-gravity theory which has a vanishing cosmological constant and contains black holes. This is do…
A Celestial Matrix Model
Arjun Kar, Lampros Lamprou, Charles Marteau +1
We construct a Hermitian random matrix model that provides a stable non-perturbative completion of Cangemi-Jackiw (CJ) gravity, a two-dimensional theory of flat spacetimes. The mat…
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…
Fefferman-Graham and Bondi Gauges in the Fluid/Gravity Correspondence
Luca Ciambelli, Charles Marteau, P. Marios Petropoulos +1
In three-dimensional gravity, we discuss the relation between the Fefferman--Graham gauge, the Bondi gauge and the Eddington--Finkelstein type of gauge, often referred to as the de…
Gauges in Three-Dimensional Gravity and Holographic Fluids
Luca Ciambelli, Charles Marteau, P. Marios Petropoulos +1
Solutions to Einstein's vacuum equations in three dimensions are locally maximally symmetric. They are distinguished by their global properties and their investigation often requir…
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…
Carroll Structures, Null Geometry and Conformal Isometries
Luca Ciambelli, Robert G. Leigh, Charles Marteau +1
We study the concept of Carrollian spacetime starting from its underlying fiber-bundle structure. The latter admits an Ehresmann connection, which enables a natural separation of t…
Carrollian Physics at the Black Hole Horizon
Laura Donnay, Charles Marteau
We show that the geometry of a black hole horizon can be described as a Carrollian geometry emerging from an ultra-relativistic limit where the near-horizon radial coordinate plays…
Two-dimensional fluids and their holographic duals
Andrea Campoleoni, Luca Ciambelli, Charles Marteau +2
We describe the dynamics of two-dimensional relativistic and Carrollian fluids. These are mapped holographically to three-dimensional locally anti-de Sitter and locally Minkowski s…
Carrollian conservation laws and Ricci-flat gravity
Luca Ciambelli, Charles Marteau
We construct the Carrollian equivalent of the relativistic energy--momentum tensor, based on variation of the action with respect to the elementary fields of the Carrollian geometr…
Flat holography and Carrollian fluids
Luca Ciambelli, Charles Marteau, Anastasios C. Petkou +2
We show that a holographic description of four-dimensional asymptotically locally flat spacetimes is reached smoothly from the zero-cosmological-constant limit of anti-de Sitter ho…
Covariant Galilean versus Carrollian hydrodynamics from relativistic fluids
Luca Ciambelli, Charles Marteau, Anastasios C. Petkou +2
We provide the set of equations for non-relativistic fluid dynamics on arbitrary, possibly time-dependent spaces, in general coordinates. These equations are fully covariant under…
