Dimensional crossover of class D real-space topological invariants
Martin Rodriguez-Vega, Terry A. Loring, Alexander Cerjan
The topological properties of a material depend on its symmetries, parameters, and spatial dimension. Changes in these properties due to parameter and symmetry variations can be un…
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…
Long-lived Zone-boundary Magnons in an Antiferromagnet
Jeongheon Choe, David Lujan, Gaihua Ye +13
Antiferromagnetic (AFM) insulators exhibit many desirable features for spintronic applications such as fast dynamics in the THz range and robustness to fluctuating external fields.…
Interlayer Dzyaloshinskii-Moriya interactions induced via non-linear phononics in bilayer van der Waals materials
Ze-Xun Lin, Bowen Ma, Wesley Roberts +2
We theoretically study the impact of light-driven structural changes via nonlinear phononics on the magnetic order of untwisted bilayer van der Waals materials. We consider an illu…
Light-induced reorientation transition in an antiferromagnetic semiconductor
Bryan T. Fichera, Baiqing Lv, Karna Morey +18
Due to the lack of a net magnetic moment, antiferromagnets possess a unique robustness to external magnetic fields and are thus predicted to play an important role in future magnet…
Magnetic Order and Strain in Hexagonal Manganese Pnictide CaMnBi
Rodrigo Humberto Aguilera-del-Toro, Mikel Arruabarrena, Aritz Leonardo +3
The manganese pnictide CaMnBi, with Mn atoms arranged in a puckered honeycomb structure, exhibits narrow-gap antiferromagnetism, and it is currently a promising candidate f…
