Holographic Banners
Matthew J. Blacker, Sean A. Hartnoll
This paper is concerned with eternal AdS black holes. The quantum cosmological future and past interior states of the black hole may be placed on an equal footing to the left and r…
Multi-mode cooling of a Bose-Einstein condensate with linear quantum feedback
Zain Mehdi, Matthew L. Goh, Matthew J. Blacker +2
We theoretically investigate measurement-based feedback control over the motional degrees of freedom of an oblate quasi-2D atomic Bose-Einstein condensate (BEC) subject to continuo…
Quantum corrections to the path integral of near extremal de Sitter black holes
Matthew J. Blacker, Alejandra Castro, Watse Sybesma +1
We study quantum corrections to the Euclidean path integral of charged and static four-dimensional de Sitter (dS) black holes near extremality. These black holes admit three di…
An atomic Fabry-Perot interferometer-based acceleration sensor for microgravity environments
Manju Perumbil, Matthew J. Blacker, Stuart S. Szigeti +1
We investigate the use of an atomic Fabry-Perot interferometer (FPI) with a pulsed non-interacting Bose-Einstein condensate (BEC) source as a space-based acceleration sensor. We de…
Radial canonical AdS gravity and
Matthew J. Blacker, Nele Callebaut, Blanca Hergueta +1
We employ an ADM deparametrization strategy to discuss the radial canonical formalism of asymptotically AdS gravity. It leads to the identification of a radial 'time' before qu…
Wheeler DeWitt States of a Charged AdS Black Hole
Matthew J. Blacker, Sirui Ning
We solve the Wheeler DeWitt equation for the planar Reissner-Nordström-AdS black hole in a minisuperspace approximation. We construct semiclassical Wheeler DeWitt states from Gauss…
Cosmological quantum states of de Sitter-Schwarzschild are static patch partition functions
Matthew J. Blacker, Sean A. Hartnoll
We solve the Wheeler-DeWitt equation in the 'cosmological interior' (the past causal diamond of future infinity) of four dimensional dS-Schwarzschild spacetimes. Within minisupersp…
Bootstrapping the Kronig-Penney Model
Matthew J. Blacker, Arpan Bhattacharyya, Aritra Banerjee
Recently, bootstrap methods from conformal field theory have been adapted for studying the energy spectrum of various quantum mechanical systems. In this paper, we consider the app…
A new approach to the quantization of the damped harmonic oscillator
Matthew J. Blacker, David L. Tilbrook
In this paper, a new approach for constructing Lagrangians for driven and undriven linearly damped systems is proposed, by introducing a redefined time coordinate and an associated…
