Magnetization process and ordering of the pyrochlore magnet in a field
Imre Hagymási, Robin Schäfer, Roderich Moessner +1
We study the pyrochlore Heisenberg antiferromagnet in a magnetic field. Using large scale density-matrix renormalization group (DMRG) calculations for clusters up to …
The pyrochlore S=1/2 Heisenberg antiferromagnet at finite temperature
Robin Schäfer, Imre Hagymási, Roderich Moessner +1
Frustrated three dimensional quantum magnets are notoriously impervious to theoretical analysis. Here we use a combination of three computational methods to investigate the three d…
Stability of edge magnetism against disorder in zigzag MoS nanoribbons
Péter Vancsó, Imre Hagymási, Pauline Castenetto +1
Molybdenum disulfide nanoribbons with zigzag edges show ferromagnetic and metallic properties based on previous \emph{ab-initio} calculations. The investigation of the role of diso…
Interaction quench and thermalization in a one-dimensional topological Kondo insulator
I. Hagymási, C. Hubig, U. Schollwöck
We study the nonequilibrium dynamics of a one-dimensional topological Kondo insulator, modelled by a -wave Anderson lattice model, following a quantum quench of the on-site inte…
