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.

Simulations of “tunnelling of the 3rd kind” (2017)
Journal Article
Mou, Z., Saffin, P. M., Tognarelli, P., & Tranberg, A. (2017). Simulations of “tunnelling of the 3rd kind”. Journal of High Energy Physics, 2017(7), https://doi.org/10.1007/JHEP07%282017%29015

We consider the phenomenon of ``tunnelling of the 3rd kind" \cite{third}, whereby a magnetic field may traverse a classically impenetrable barrier by pair creation of unimpeded quantum fermions. These propagate through the barrier and generate a magn... Read More about Simulations of “tunnelling of the 3rd kind”.

Simulations of Cold Electroweak Baryogenesis: finding the optimal quench time (2017)
Journal Article
Mou, Z., Saffin, P. M., & Tranberg, A. (2017). Simulations of Cold Electroweak Baryogenesis: finding the optimal quench time. Journal of High Energy Physics, 2017(7), https://doi.org/10.1007/JHEP07%282017%29010

We revisit the numerical computation of the baryon asymmetry from Cold Electroweak Baryogenesis given the physical Higgs mass. We investigate the dependence of the asymmetry on the speed at which electroweak symmetry breaking takes place. The maximu...

Simulations of Cold Electroweak Baryogenesis: hypercharge U(1) and the creation of helical magnetic fields (2017)
Journal Article
Mou, Z., Saffin, P. M., & Tranberg, A. (2017). Simulations of Cold Electroweak Baryogenesis: hypercharge U(1) and the creation of helical magnetic fields. Journal of High Energy Physics, 2017(6), https://doi.org/10.1007/JHEP06%282017%29075

We perform numerical simulations of Cold Electroweak Baryogenesis, including for the first time in the Bosonic sector the full electroweak gauge group SU(2)×U(1) and CP-violation. We find that the maximum generated baryon asymmetry is reduced by a fa... Read More about Simulations of Cold Electroweak Baryogenesis: hypercharge U(1) and the creation of helical magnetic fields.

Highly excited strings I: Generating function (2017)
Journal Article
Skliros, D. P., Copeland, E. J., & Saffin, P. M. (in press). Highly excited strings I: Generating function. Nuclear Physics B, https://doi.org/10.1016/j.nuclphysb.2016.12.022

This is the first of a series of detailed papers on string amplitudes with highly excited strings (HES). In the present paper we construct a generating function for string amplitudes with generic HES vertex operators using a fixed-loop momentum forma...
