Revisiting Spherically Symmetric Spacetime I: Geometro-Hydrodynamics
Puttarak Jai-akson, Yuki Yokokura
This series of works revisits the geometry, dynamics, and covariant phase space of spherically symmetric spacetimes with the aim of exploring the thermodynamics of spacetime from t…
Foundations of Carrollian Geometry
Luca Ciambelli, Puttarak Jai-akson
Carrollian physics provides the natural framework for describing null hypersurfaces. This review explores the geometry of Carrollian manifolds -- spaces endowed with a degenerate m…
Geometry of Carrollian Stretched Horizons
Laurent Freidel, Puttarak Jai-akson
In this paper, we present a comprehensive toolbox for studying Carrollian stretched horizons, encompassing their geometry, dynamics, symplectic geometry, symmetries, and correspond…
Carrollian hydrodynamics and symplectic structure on stretched horizons
Laurent Freidel, Puttarak Jai-akson
The membrane paradigm displays underlying connections between a timelike stretched horizon and a null boundary (such as a black hole horizon) and bridges the gravitational dynamics…
Carrollian hydrodynamics from symmetries
Laurent Freidel, Puttarak Jai-akson
In this work, we revisit Carrollian hydrodynamics, a type of non-Lorentzian hydrodynamics which has recently gained increasing attentions due to its underlying connection with dyna…
Electromagnetic duality and central charge from first order formulation
Marc Geiller, Puttarak Jai-akson, Abdulmajid Osumanu +1
In the context of the infrared triangle there have been recent discussions on the existence and the role of dual charges. We present a new viewpoint on dual magnetic charges in …
Extended actions, dynamics of edge modes, and entanglement entropy
Marc Geiller, Puttarak Jai-akson
In this work we propose a simple and systematic framework for including edge modes in gauge theories on manifolds with boundaries. We argue that this is necessary in order to achie…
Black hole merger estimates in Einstein-Maxwell and Einstein-Maxwell-dilaton gravity
Puttarak Jai-akson, Auttakit Chatrabhuti, Oleg Evnin +1
The recent birth of gravitational wave astronomy invites a new generation of precision tests of general relativity. Signatures of black hole (BH) mergers must be systematically exp…
Detailed ultraviolet asymptotics for AdS scalar field perturbations
Oleg Evnin, Puttarak Jai-akson
We present a range of methods suitable for accurate evaluation of the leading asymptotics for integrals of products of Jacobi polynomials in limits when the degrees of some or all…
Ultraviolet asymptotics for quasiperiodic AdS_4 perturbations
Ben Craps, Oleg Evnin, Puttarak Jai-akson +1
Spherically symmetric perturbations in AdS-scalar field systems of small amplitude epsilon approximately periodic on time scales of order 1/epsilon^2 (in the sense that no signific…
