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…
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…
Ring states in topological materials
Raquel Queiroz, Roni Ilan, Zhida Song +2
Ingap states in semiconductors are commonly characterized by hydrogenic models within the effective mass approximation. However, when impurities are strong, this description fails.…
