Analyzing student conceptual understanding of resistor networks using binary, descriptive, and computational questions
Abid H. Mujtaba
This paper presents a case-study assessing and analyzing student engagement with and responses to binary, descriptive, and computational questions testing the concepts underlying r…
Ergoregions in Magnetised Black Hole Spacetimes
G. W. Gibbons, A. H. Mujtaba, C. N. Pope
The spacetimes obtained by Ernst's procedure for appending an external magnetic field to a seed Kerr-Newman black hole are commonly believed to be asymptotic to the static Melv…
The Hoop Conjecture for Black Rings
A. H. Mujtaba, C. N. Pope
A precise formulation of the hoop conjecture for four-dimensional spacetimes proposes that the Birkhoff invariant βfor an apparent horizon in a spacetime with mass M should satisfy…
Homogeneous Einstein metrics on SU(n)
Abid H. Mujtaba
It is known that every compact simple Lie group admits a bi-invariant homogeneous Einstein metric. In this paper we use two ansatz to probe the existence of additional inequivalent…
