Almost-Killing equation: Stability, hyperbolicity, and black hole Gauss law
Justin C. Feng, Edgar Gasperín, Jarrod L. Williams
We examine the Hamiltonian formulation and hyperbolicity of the almost-Killing equation (AKE). We find that for all but one parameter choice, the Hamiltonian is unbounded, and in s…
A new laser-ranged satellite for General Relativity and space geodesy: IV. Thermal drag and the LARES 2 space experiment
Ignazio Ciufolini, Richard A. Matzner, Justin C. Feng +6
In three previous papers we presented the LARES 2 space experiment aimed at a very accurate test of frame-dragging and at other tests of fundamental physics and measurements of spa…
New class of generalized coupling theories
Justin C. Feng, Sante Carloni
We propose a new class of gravity theories which are characterized by a nontrivial coupling between the gravitational metric and matter mediated by an auxiliary rank-2 tensor. The…
Black hole in a superconducting plasma
Chinmoy Bhattacharjee, Justin C. Feng, S. M. Mahajan
The generalized vortical formalism provides an electrodynamic description for superconducting states---in the generalized vortical formalism, a superconducting state may be defined…
