Localizing quantum fields with time-dependent potentials
Boris Ragula, Bruno de S. L. Torres, Erik Schnetter +1
In this paper we study the effect of localizing quantum field degrees of freedom by dynamically growing cavity walls through a time-dependent potential. We use our results to show…

Numerical evolution of Maxwell's equations for wavefronts propagating through a spherical gravitational potential
Annamalai P. Shanmugaraj, Erik Schnetter, Sofie Marie Koksbang
We present a scheme for numerically solving Maxwell's equations in a weakly perturbed spacetime without introducing the usual geometric optics approximation. Using this scheme, we…

Formulating the complete initial boundary value problem in numerical relativity to model black hole echoes
Conner Dailey, Erik Schnetter, Niayesh Afshordi
In an attempt to simulate black hole echoes (generated by potential quantum-gravitational structure) in numerical relativity, we recently described how to implement a reflecting bo…
