Pathologies in Asymptotically Lifshitz Spacetimes
Keith Copsey, Robert Mann
There has been significant interest in the last several years in studying possible gravitational duals, known as Lifshitz spacetimes, to anisotropically scaling field theories by a…
States of Negative Energy and
Keith Copsey, Robert B. Mann
We develop a careful definition of energy for nonsupersymmetric warped product asymptotically solutions which include a nonzero p-form. In the case of an electri…
Bubbles Unbound: Bubbles of Nothing Without Kaluza-Klein
Keith Copsey
I present analytic time symmetric initial data for five dimensions describing ``bubbles of nothing'' which are asymptotically flat in the higher dimensional sense, i.e. there is no…
Gravity Dual of Gauge Theory on S^2 x S^1 x R
Keith Copsey, Gary T. Horowitz
We (numerically) construct new static, asymptotically AdS solutions where the conformal infinity is the product of time and S^2 x S^1. There always exist a family of solutions in w…
The Role of Dipole Charges in Black Hole Thermodynamics
Keith Copsey, Gary T. Horowitz
Modern derivations of the first law of black holes appear to show that the only charges that arise are monopole charges that can be obtained by surface integrals at infinity. Howev…
Through the Looking Glass: AdS-FT with time dependent boundary conditions and black hole formation
Keith Copsey
I solve for the behavior of scalars in Lorentzian AdS with time dependent boundary conditions, focusing in particular on the dilaton. This corresponds, via the AdS-CFT corresponden…
