How to avoid a swift kick in the chameleons (2016)
Journal Article
Padilla, A., Platts, E., Stefanyszyn, D., Walters, A., Weltman, A., & Wilson, T. (2016). How to avoid a swift kick in the chameleons. Journal of Cosmology and Astroparticle Physics, 2016, Article 58. https://doi.org/10.1088/1475-7516/2016/03/058

Recently, it was argued that the conformal coupling of the chameleon to matter fields created an issue for early universe cosmology. As standard model degrees of freedom become non-relativistic in the early universe, the chameleon is attracted toward... Read More about How to avoid a swift kick in the chameleons.

Sussing merger trees: stability and convergence (2016)
Journal Article
Wang, Y., Pearce, F. R., Knebe, A., Schneider, A., Srisawat, C., Tweed, D., …Lin, W. (2016). Sussing merger trees: stability and convergence. Monthly Notices of the Royal Astronomical Society, 459(2), https://doi.org/10.1093/mnras/stw726

Merger trees are routinely used to follow the growth and merging history of dark matter haloes and subhaloes in simulations of cosmic structure formation. Srisawat et al. compared a wide range of merger-tree-building codes. Here we test the influence... Read More about Sussing merger trees: stability and convergence.

Probabilities and signalling in quantum field theory (2016)
Journal Article
Dickinson, R., Forshaw, J., & Millington, P. (2016). Probabilities and signalling in quantum field theory. Physical Review D, 93(6), Article 065054. https://doi.org/10.1103/PhysRevD.93.065054

We present an approach to computing probabilities in quantum field theory for a wide class of source-detector models. The approach works directly with probabilities and not with squared matrix elements, and the resulting probabilities can be written...

Hole spin injection from a GaMnAs layer into GaAs-AlAs-InGaAs resonant tunneling diodes (2016)
Journal Article
Rodrigues, D., Brasil, M., Orlita, M., Kunc, J., Galeti, H., Henini, M., …H.V.A., Y. (2016). Hole spin injection from a GaMnAs layer into GaAs-AlAs-InGaAs resonant tunneling diodes. Journal of Physics D: Applied Physics, 49(16), https://doi.org/10.1088/0022-3727/49/16/165104

We have investigated the polarization-resolved electroluminescence (EL) of a p–i–n GaAs/AlAs/InGaAs resonant tunneling diode (RTD) containing a GaMnAs (x  =  5%) spin injector under high magnetic fields. We demonstrate that under hole resonant tunnel... Read More about Hole spin injection from a GaMnAs layer into GaAs-AlAs-InGaAs resonant tunneling diodes.

Evolution and spherical collapse in Einstein-Æther theory and Hořava gravity (2016)
Journal Article
Bhattacharyya, J., Coates, A., Colombo, M., & Sotiriou, T. P. (2016). Evolution and spherical collapse in Einstein-Æther theory and Hořava gravity. Physical Review D, 93(6), Article 64056. https://doi.org/10.1103/PhysRevD.93.064056

We compare the initial value formulation of the low-energy limit of (nonprojectable) Hořava gravity to that of Einstein-æther theory when the æther is assumed to be hypersurface orthogonal at the level of the field equations. This comparison clearly... Read More about Evolution and spherical collapse in Einstein-Æther theory and Hořava gravity.

Disformally self-tuning gravity (2016)
Journal Article
Emond, W. T., & Saffin, P. M. (in press). Disformally self-tuning gravity. Journal of High Energy Physics, 2016(3), https://doi.org/10.1007/JHEP03%282016%29161

We extend a previous self-tuning analysis of the most general scalar-tensor theory of gravity in four dimensions with second order field equations by considering a generalized coupling to the matter sector. Through allowing a disformal coupling to ma... Read More about Disformally self-tuning gravity.
