Euler-Heisenberg actions in higher dimensions
We extend Schwinger's proper-time formalism to provide a method for computing the one-loop effective action for both spinor and scalar quantum electrodynamics in d=2n>4 dimensions. We give the…

Symplectic structure in open string field theory III: Electric field
We use a new formula for the symplectic structure on the phase space of open string field theory to evaluate the energy of a D-brane carrying a constant electric flux. This is shown to be consistent…

Supersymmetry and Attractors in N = 4 Supergravity: The Superconformal Approach
In this paper, we study the attractor mechanism for extremal, spherically symmetric black holes in pure, untruncated, N=4 Poincaré supergravity, which we demonstrate numerically. We further study the…

On equivalent methods for functional determinants
Computing functional determinants of differential operators is central to any field-theoretical calculation relying on a saddle-point expansion. A variety of approaches is available for the…

Approaching a dynamical extreme black hole horizon
We give an explicit closed form description of the late-time near-horizon approach to dynamical extreme Reissner-Nordstrom (DERN) black holes. These are spherically symmetric dynamical solutions of…

Universal Nonminimal Coupling-to-Starobinsky Matching and a Single-Field Attractor
We establish an off-shell commutativity theorem in 4D parity-even quadratic gravity that the Hubbard-Stratonovich/Legendre lifts, algebraic elimination of auxiliaries, including the torsionless…

On-shell representation and further instances of the 2-split behavior of amplitudes
The newly discovered splitting behavior of tree-level scattering amplitudes of particles and strings has been expressed in terms of currents containing one off-shell leg. In this work, we explain how…

Work distribution and fluctuation theorem in AdS/CFT
From the AdS/CFT dictionary, we derive a bulk dual of the work distribution defined by the two-point measurement on the boundary, yielding a bulk formulation of the Tasaki-Crooks fluctuation theorem.…

Microstate counting from defects in de Sitter
We explore the microscopic origin of de Sitter entropy using a Lorentzian path-integral approach. We construct a Hilbert space whose states are associated with configurations of thin shells or…

The One-Loop QCD β-Function as an Index
In this letter we show that the one-loop QCD β-function can be obtained from an index theorem on twistor space. This is achieved by recalling that the θ-angle of self-dual gauge theory flows…

Foundations of Carrollian Geometry
Carrollian physics provides the natural framework for describing null hypersurfaces. This review explores the geometry of Carrollian manifolds -- spaces endowed with a degenerate metric. We begin…

Dynamical Similarity in Multisymplectic Field Theory
Symmetry under a particular class of non-strictly canonical transformation may be used to identify, and subsequently excise degrees of freedom which do not contribute to the closure of the algebra of…

Fluid Boundary Conditions from AdS/BCFT
In this paper, we initiate our program to classify conformal fluid boundary conditions, by utilizing the fluid/gravity correspondence in the AdS/BCFT correspondence. The AdS/BCFT correspondence is a…

Four-dimensional de Sitter cosmology on D-branes nucleated in an asymptotically AdS5× T1,1 background
We find four-dimensional de Sitter (dS) vacuum solutions on probe D-branes nucleating in a background, which is a U(1) charged black hole solution of IIB supergravity, including stringy corrections.…
