Driven toroidal helix as a generalization of Kapitzas pendulum
J. F. Gloy, A. Siemens, P. Schmelcher
We explore a model system consisting of a particle confined to move along a toroidal helix while being exposed to a static potential as well as a driving force due to a harmonicall…
External field-induced dynamics of a charged particle on a closed helix
Ansgar Siemens, Peter Schmelcher
We investigate the dynamics of a charged particle confined to move on a toroidal helix while being driven by an external time-dependent electric field. The underlying phase space i…
Tunable Order of Helically Confined Charges
Ansgar Siemens, Peter Schmelcher
We investigate a system of equally charged Coulomb-interacting particles confined to a toroidal helix in the presence of an external electric field. Due to the confinement, the par…
Controlled creation and stability of kπ-skyrmions on a discrete lattice
Julian Hagemeister, Ansgar Siemens, Levente Rózsa +2
We determine sizes and activation energies of kπ-skyrmions on a discrete lattice using the Landau- Lifshitz-Gilbert equation and the geodesic nudged elastic band method. The employ…
