Weber blockade in superconducting nanowires
Tyler Morgan-Wall, Benjamin Leith, Nikolaus Hartman +2
We have measured the critical current as a function of magnetic field in short and narrow superconducting aluminum nanowires. In the range of magnetic fields in which vortices can…
Non-minimally coupled multi-scalar black holes
Ben M. Leith, Alex B. Nielsen
We study the static, spherically symmetric black hole solutions for a non-minimally coupled multi-scalar theory. We find numerical solutions for values of the scalar fields when a…
Gravitational energy as dark energy: Concordance of cosmological tests
Ben M. Leith, S. C. Cindy Ng, David L. Wiltshire
We provide preliminary quantitative evidence that a new solution to averaging the observed inhomogeneous structure of matter in the universe [gr-qc/0702082, arxiv:0709.0732], may l…
Gauss-Bonnet cosmologies: crossing the phantom divide and the transition from matter dominance to dark energy
Ben M. Leith, Ishwaree P. Neupane
Dark energy cosmologies with an equation of state parameter less than -1 are often found to violate the null energy condition and show unstable behaviour. A solution to this pr…
Type Ia supernovae tests of fractal bubble universe with no cosmic acceleration
B. M. N. Carter, B. M. Leith, S. C. C. Ng +2
The unexpected dimness of Type Ia supernovae at redshifts z >~ 1 has over the past 7 years been seen as an indication that the expansion of the universe is accelerating. A new mode…
