Exploring magnetic solitons using DMRG — Anton Wöllert and •Andreas Honecker — Institut für theoretische Physik - Friedrich Hund Platz 1, Göttingen, Germany

We study the anisotropic ferromagnetic frustrated Heisenberg spin-1/2 chain out of equilibrium. The aim is to find solitonic structures using the adaptive time dependent density matrix renormalization group (t-DMRG). This should be achieved by quenching the system from an excited state and examining the real time evolution. Especially parts of the phase diagram are analyzed, where solitons can be observed in the classical model.
