Simulating magnetic antiskyrmions on the lattice
Juan C. Criado, Peter D. Hatton, Sebastian Schenk +2
Magnetic skyrmions are topologically protected spin structures that naturally emerge in magnetic materials. While a vast amount of effort has gone into the study of their propertie…
Challenging the Stability of Light Millicharged Dark Matter
Joerg Jaeckel, Sebastian Schenk
We investigate the cosmological stability of light bosonic dark matter carrying a tiny electric charge. In the wave-like regime of high occupation numbers, annihilation into gauge…
Exploring instantons with spin-lattice systems
Sebastian Schenk, Michael Spannowsky
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 ins…
Very Light Asymmetric Dark Matter
Gonzalo Alonso-Álvarez, Julia Gehrlein, Joerg Jaeckel +1
Very light dark matter is usually taken to consist of uncharged bosons such as axion-like particles or dark photons. Here, we consider the prospect of very light, possibly even sub…
Exploring High Multiplicity Amplitudes: The QM Analogue of the Spontaneously Broken Case
Joerg Jaeckel, Sebastian Schenk
Calculations of high multiplicity Higgs amplitudes exhibit a rapid growth that may signal an end of perturbative behavior or even the need for new physics phenomena. As a step towa…
Exploring High Multiplicity Amplitudes in Quantum Mechanics
Joerg Jaeckel, Sebastian Schenk
Calculations of amplitudes in scalar field theories at very high multiplicities exhibit an extremely rapid growth with the number of final state particles. This either…
