Ultrafast Light-Induced Magnetoelectric Effect in van der Waals Magnetic Semiconductor Heterostructures
Wenyi Zhou, Ravi Kumar Bandapelli, Hari Paudyal +8
Atomic-scale heterostructures of van der Waals (vdW) magnets and semiconductors provide a unique environment for exploring magnetic dynamics. In contrast to typical photothermal ex…
Cut-and-Project Density Functional Theory for Quasicrystals
Gavin N. Nop, Jonathan D. H. Smith, Thomas Koschny +1
Cut-and-project from a symmetric structure in a higher-dimensional space is a standard method for describing the structure of a large class of quasicrystals. By means of a novel lo…
Quantum Coherence of Rare-Earth Ions in Heterogeneous Photonic Interfaces
Henry C. Hammer, Hassan A. Bukhari, Yogendra Limbu +6
Harnessing rare-earth ions in oxides for quantum networks requires integration with bright emitters in III-V semiconductors, but local disorder and interfacial noise limit their op…
Intrinsic Berry phase contribution to Hall conductivity in CoS
Tamal Kumar Dalui, Hari Paudyal, Durga Paudyal +1
In Weyl semi-metals, the conduction and valence bands intersect at distinct points on the Brillouin zone (Weyl points), which act as monopoles of Berry curvature in momentum space.…
Functionalized CrC MXenes: Novel Magnetic Semiconductors
Yogendra Limbu, Hari Paudyal, Eudes Gomes da Silva +3
We report an \textit{ab initio} investigation of functionalized and 3-electrons doped CrC MXenes. Upon functionalization, the CrC becomes chemically, dynamically, and me…
Stability, electronic quantum states, and magnetic interactions of Er ions in GaO
Yogendra Limbu, Hari Paudyal, Michael E. Flatté +1
The chemical, structural, mechanical, and dynamical stabilities of the - and -GaO are confirmed from respective negative formation energies, negative cohesive energ…
