Topological Hall Response from Canted Antiferromagnetic Order in -Electron Kagome Systems
Waquar Ahmed, Steffen Schäfer, Pierre Lombardo +2
In a two-dimensional kagome monolayer, a nontrivial intrinsic Berry curvature may arise in the -electron system from the interaction with a non-collinear spin order induced by a…

Quantum dot-based device for high-performance magnetic microscopy and spin filtering in the Kondo regime
Pierre Lombardo, Imam Makhfudz, Steffen Schäfer +1
We propose a nanoscale device consisting of a double quantum dot with a full exchange and pair hopping interaction. In this design, the current can only flow through the upper dot,…

Quantum Anomalous Hall Effect in -Electron Kagome Systems: Chern Insulating States from Transverse Spin-Orbit Coupling
Imam Makhfudz, Mikhail Cherkasskii, Mohammad Alipourzadeh +5
The possibility of quantum anomalous Hall effect (QAHE) in two-dimensional kagome systems with -orbital electrons is studied within a multi-orbital tight-binding model. We conce…
