Control of the Néel vector in the quantum antiferromagnetic honeycomb lattice
Asliddin Khudoyberdiev, Dag-Björn Hering, Vanessa Sulaiman +1
The switching of antiferromagnetic order and its efficient control promise to enable ultrafast manipulation of data and large storage capacity. Recently, the time-dependent Schwing…

Quantum decay of magnons in the unfrustrated honeycomb Heisenberg model
Calvin Krämer, Calvin Krämer, Dag-Björn Hering +6
We investigate the physical properties of elementary magnon excitations of the ordered antiferromagnetic Heisenberg model on the honeycomb lattice using quantum Monte Carlo (QMC) s…

Quantum effects in the magnon spectrum of 2D altermagnets via continuous similarity transformations
Raymond Wiedmann, Dag-Björn Hering, Vanessa Sulaiman +3
We investigate quantum effects on magnon excitations in a minimal spin-1/2 Heisenberg model for 2D altermagnets on the square lattice. A continuous similarity transformation is app…
