Light-induced pseudo-magnetic fields in three-dimensional topological semimetals
Arpit Raj, Swati Chaudhary, Martin Rodriguez-Vega +3
In this work, we show that suitably designed spatially varying linearly polarized light provides a versatile route to generate and control pseudo-magnetic fields in Weyl semimetals…
Non-Hermitian magnetic moment
Bar Alon, Moshe Goldstein, Roni Ilan
We construct a semiclassical theory for electrons in a non-Hermitian periodic system subject to perturbations varying slowly in space and time. We derive the energy of the wavepack…
Defect-Bound Excitons in Topological Materials
Roni Majlin Skiff, Sivan Refaely-Abramson, Raquel Queiroz +1
Excitons, bound states of electrons and holes, are affected by the properties of the underlying band structure of a material. Defects in lattice systems may trap electronic defect…
Quantum geometry of non-Hermitian systems
Jan Behrends, Roni Ilan, Moshe Goldstein
The Berry curvature characterizes one aspect of the geometry of quantum states. It materializes, among other consequences, as an anomalous velocity of wave packets. In non-Hermitia…
Intertwined topological phases in TaAs2 nanowires with giant magnetoresistance and quantum coherent surface transport
Anand Roy, Anna Eyal, Roni Majlin Skiff +7
Nanowires (NWs) of topological materials are emerging as an exciting platform to probe and engineer new quantum phenomena that are hard to access in bulk phase. Their quasi-one-dim…
Shift and Polarization of Excitons from Quantum Geometry
Carolina Paiva, Tobias Holder, Roni Ilan
Despite a long history, certain aspects of excitons - the bound inter-band states which form when a valence band hole and a conduction band electron pair - have remained relatively…
