All product eigenstates in Heisenberg models from a graphical construction
Felix Gerken, Ingo Runkel, Christoph Schweigert +1
Recently, large degeneracy based on product eigenstates has been found in spin ladders, kagome-like lattices, and motif magnetism, connected to spin liquids, anyonic phases, and qu…
Controlling Majorana hybridization in magnetic chain-superconductor systems
Oladunjoye A. Awoga, Ioannis Ioannidis, Archana Mishra +3
We propose controlling the hybridization between Majorana zero modes at the ends of magnetic adatom chains on superconductors by an additional magnetic adatom deposited close by. B…
Ground State Properties of Quantum Skyrmions described by Neural Network Quantum States
Ashish Joshi, Robert Peters, Thore Posske
We investigate the ground state properties of quantum skyrmions in a ferromagnet using variational Monte Carlo with the neural network quantum state as variational ansatz. We study…
The quantum skyrmion Hall effect in f electron systems
Robert Peters, Jannis Neuhaus-Steinmetz, Thore Posske
The flow of electric current through a two-dimensional material in a magnetic field gives rise to the family of Hall effects. The quantum versions of these effects accommodate robu…
Quantum spin helices more stable than the ground state: onset of helical protection
Stefan Kühn, Felix Gerken, Lena Funcke +4
Topological magnetic structures are promising candidates for resilient information storage. An elementary example are spin helices in one-dimensional easy-plane quantum magnets. To…
