Recrudescence of massive fermion production by oscillons (2017)
Journal Article
Saffin, P. M. (in press). Recrudescence of massive fermion production by oscillons. Journal of High Energy Physics, 2017(7), Article 126. https://doi.org/10.1007/JHEP07%282017%29126

We bring together the physics of preheating, following a period of inflation, and the dynamics of non-topological solitons, namely oscillons. We show that the oscillating condensate that makes up an oscillon can be an efficient engine for producing h... Read More about Recrudescence of massive fermion production by oscillons.

A mean field model for movement induced changes in the beta rhythm (2017)
Journal Article
Byrne, Á., Brookes, M. J., & Coombes, S. (2017). A mean field model for movement induced changes in the beta rhythm. Journal of Computational Neuroscience, 43(2), https://doi.org/10.1007/s10827-017-0655-7

In electrophysiological recordings of the brain, the transition from high amplitude to low amplitude signals are most likely caused by a change in the synchrony of underlying neuronal population firing patterns. Classic examples of such modulations... Read More about A mean field model for movement induced changes in the beta rhythm.

Evolution of semilocal string networks: II. Velocity estimators (2017)
Journal Article
Lopez-Eiguren, A., Urrestilla, J., Achúcarro, A., Avgoustidis, A., & Martins, C. (2017). Evolution of semilocal string networks: II. Velocity estimators. Physical Review D, 96, Article 023526. https://doi.org/10.1103/PhysRevD.96.023526

We continue a comprehensive numerical study of semilocal string networks and their cosmological evolution. These can be thought of as hybrid networks comprised of (non-topological) string segments, whose core structure is similar to that of Abelian H...

Background

Intra-neural microstimulation (INMS) is a technique that allows the precise delivery of low-current electrical pulses into human peripheral nerves. Single unit INMS can be used to stimulate individual afferent nerve fibres during micron...

Cyclotron motion of charge carriers in metals and semiconductors leads to Landau quantization and magneto-oscillatory behavior in their properties. Cryogenic temperatures are usually required to observe these oscillations. We show that graphene super...
