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...

Probing dark matter clumps, strings and domain walls with gravitational wave detectors (2021)
Journal Article
Jaeckel, J., Schenk, S., & Spannowsky, M. (2021). Probing dark matter clumps, strings and domain walls with gravitational wave detectors. The European Physical Journal C, 81(9), Article 828. https://doi.org/10.1140/epjc/s10052-021-09604-9

Gravitational wave astronomy has recently emerged as a new way to study our Universe. In this work, we survey the potential of gravitational wave interferometers to detect macroscopic astrophysical objects comprising the dark matter. Starting from th...

Exploring instantons in nonlinear sigma models with spin-lattice systems (2021)
Journal Article
Schenk, S., & Spannowsky, M. (2021). Exploring instantons in nonlinear sigma models with spin-lattice systems. Physical Review B, 103(14), Article 144436. https://doi.org/10.1103/physrevb.103.144436

Instanton processes are present in a variety of quantum field theories relevant to high energy as well as condensed matter physics. While they have led to important theoretical insights and physical applications, their underlying features often remai...
