Rotating black holes in Einstein-aether theory
Alexander Adam, Pau Figueras, Ted Jacobson +1
We introduce new methods to numerically construct for the first time stationary axisymmetric black hole solutions in Einstein-aether theory and study their properties. The key tech…
Generalized hypergeometric expansion related to the Hurwitz zeta function
Alexander Adam
We study the incomplete Mellin transformation of the fractional part and the related log-sine function when composed by an affine complex map. We evaluate the corresponding integra…
Horocycle averages on closed manifolds and transfer operators
Alexander Adam, Viviane Baladi
We adapt to Anosov flows on compact manifolds a construction for discrete-time hyperbolic dynamics (), obtaining anisotropic Banach or Hilbert spaces on which the…
Zero is a resonance of every Schottky surface
Alexander Adam, Anke Pohl, Alexander Weiße
For certain spectral parameters we find explicit eigenfunctions of transfer operators for Schottky surfaces. Comparing the dimension of the eigenspace for the spectral parameter ze…
A transfer-operator-based relation between Laplace eigenfunctions and zeros of Selberg zeta functions
Alexander Adam, Anke Pohl
Over the last few years Pohl (partly jointly with coauthors) developed dual `slow/fast' transfer operator approaches to automorphic functions, resonances, and Selberg zeta function…
Generic non-trivial resonances for Anosov diffeomorphisms
Alexander Adam
We study real analytic perturbations of hyperbolic linear automorphisms on the 2-torus. The Koopman and the transfer operator are nuclear of order 0 when acting on a suitable Hilbe…
Bosonic Fractionalisation Transitions
Alexander Adam, Benedict Crampton, Julian Sonner +1
At finite density, charge in holographic systems can be sourced either by explicit matter sources in the bulk or by bulk horizons. In this paper we find bosonic solutions of both t…
A numerical approach to finding general stationary vacuum black holes
Alexander Adam, Sam Kitchen, Toby Wiseman
The Harmonic Einstein equation is the vacuum Einstein equation supplemented by a gauge fixing term which we take to be that of DeTurck. For static black holes analytically continue…
