Dynamical wormholes
Ben Kain
We numerically investigate the dynamical evolution of spherically symmetric charge free wormholes. We concentrate on two specific examples, both of which exhibit wormhole expansion…
How to Engage Active Pedagogy with Physics Faculty: Watch Out for Powerlessness
Andria C. Schwortz, Michael Frey, Andrea C. Burrows Borowczak
Despite the large body of research showing that students in STEM classes at all levels learn better via active learning than they do via lecture, post-secondary physics and astrono…
On Axially Symmetric Perturbations of Kerr Black Hole Spacetimes
Nishanth Gudapati
The lack of a positive-definite and conserved energy is a serious obstacle in the black hole stability problem. In this work, we will show that there exists a positive-definite and…
Dynamical evolution and stability of quantum corrected Schwarzschild black holes in semiclassical gravity
Ben Kain
The Schwarzschild solution describes a classical static black hole in general relativity. When general relativity is extended by including semiclassical corrections in the form of…
Quantum corrected Einstein-Yang-Mills black holes in semiclassical gravity
Ben Kain
We study Einstein-Yang-Mills (EYM) black holes in semiclassical gravity by including in the field equations the expectation value of a renormalized energy-momentum tensor in the Po…
Flow rate from a vertical silo with a tilted orifice
Ryan Kozlowski, Luis A. Pugnaloni
The flow of dry granular materials from silos is of great practical interest in industry and of theoretical import for understanding multiphase dynamics. Recent studies have demons…
