Photostriction-Driven Phase Transition in Layered Chiral NbOX Crystals: Electrical-Field-Controlled Enantiomer Selectivity
Jorge Cardenas-Gamboa, Martin Gutierrez-Amigo, Aritz Leonardo +5
Chiral crystals offer an unique platform for controlling structural handedness through external stimuli. However, the ability to select between structural enantiomers remains chall…
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…
Giant Shift Current in Electrically-Tunable Superlattice Bilayer Graphene
Nabil Atlam, Swati Chaudhary, Arpit Raj +4
Recent introduction of superlattice potentials has opened new avenues for engineering tunable electronic band structures featuring topologically nontrivial moiré-like bands. Here…
Magnetocrystalline anisotropy of FeNi and FeCo along the Bain path
Nica Jane B. Ferrer, Gregory A. Fiete
We theoretically investigate magnetic anisotropy in materials with non-critical elements to determine which symmetry conditions and atomic shell filling favor enhanced magnetic ani…
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.…
High-accuracy evaluation of non-thermal magnetic states beyond spin-wave theory: applications to higher-energy states
Wesley Roberts, Michael Vogl, Roderich Moessner +1
We present an approximation scheme based on selective Hilbert space truncation for characterizing non-thermal states of magnetic systems beyond spin-wave theory. We study applicati…
