Non-resonant New Physics in Top Pair Production at Hadron Colliders (2011)
Journal Article
Degrande, C., Gérard, J., Grojean, C., Maltoni, F., & Servant, G. (2011). Non-resonant New Physics in Top Pair Production at Hadron Colliders. Journal of High Energy Physics, 2011(3), Article 125. https://doi.org/10.1007/jhep03%282011%29125

We use top quark pair production as a probe of top-philic non-resonant new physics. Following a low energy effective field theory approach, we calculate several key observables in top quark pair production at hadron colliders (e.g., total cross secti...

f(T) Gravity and local Lorentz invariance (2011)
Journal Article
Li, B., Sotiriou, T., & Barrow, J. (2011). f(T) Gravity and local Lorentz invariance. Physical Review D, 83(6), Article 064035. https://doi.org/10.1103/physrevd.83.064035

We show that in theories of generalized teleparallel gravity, whose Lagrangians are algebraic functions of the usual teleparallel Lagrangian, the action and the field equations are not invariant under local Lorentz transformations. We also argue that... Read More about f(T) Gravity and local Lorentz invariance.

Spatial two-particle NOON-states in periodically shaken three-well potentials (2011)
Journal Article
Stiebler, K., Gertjerenken, B., Teichmann, N., & Weiss, C. (2011). Spatial two-particle NOON-states in periodically shaken three-well potentials. Journal of Physics B: Atomic, Molecular and Optical Physics, 44(5), https://doi.org/10.1088/0953-4075/44/5/055301

Few-particle dynamics in a three-well potential are investigated numerically. It is shown that periodically shaking the potential can considerably increase the fidelity of emerging spatial quantum superpositions. Such NOON-states are important for qu...

Voids in coupled scalar field cosmology (2011)
Journal Article
Li, B. (2011). Voids in coupled scalar field cosmology. Monthly Notices of the Royal Astronomical Society, 411(4), 2615-2627. https://doi.org/10.1111/j.1365-2966.2010.17867.x

We study the properties of voids in two different types of coupled scalar field theories. Due to the fifth force produced by the scalar field coupling, the matter particles feel stronger attraction amongst each other and cluster more quickly than the...
