Simulating anti-skyrmions on a lattice (2022)
Journal Article
Criado, J. C., Schenk, S., Spannowsky, M., Hatton, P. D., & Turnbull, L. (2022). Simulating anti-skyrmions on a lattice. Scientific Reports, 12, Article 19179. https://doi.org/10.1038/s41598-022-22043-0

Magnetic skyrmions are topological spin structures that naturally emerge in magnetic materials. While a vast amount of effort has gone into the study of their properties, their counterpart of opposite topological charge, the anti-skyrmion, has not re...

Multiparticle amplitudes in a scalar EFT (2022)
Journal Article
Khoze, V. V., & Schenk, S. (2022). Multiparticle amplitudes in a scalar EFT. Journal of High Energy Physics, 2022(5), Article 134. https://doi.org/10.1007/jhep05%282022%29134

At sufficiently high energies the production of a very large number of particles is kinematically allowed. However, it is well-known that already in the simplest case of a weakly-coupled massive λφ4 theory, n-particle amplitudes become non-perturbati...

The breakdown of resummed perturbation theory at high energies (2022)
Journal Article
Schenk, S. (2022). The breakdown of resummed perturbation theory at high energies. Journal of High Energy Physics, 2022(3), Article 100. https://doi.org/10.1007/jhep03%282022%29100

Calculations of high-energy processes involving the production of a large number of particles in weakly-coupled quantum field theories have previously signaled the need for novel non-perturbative behavior or even new physical phenomena. In some scena... Read More about The breakdown of resummed perturbation theory at high energies.
