Spin lifetime anisotropy in graphene induced by the SiO2 interface
Aron W. Cummings, Chunhao Guo, Andrew Grieder +5
Understanding how common dielectric substrates influence the spin transport properties of graphene is essential for advancing graphene-based spintronic technologies. Here we use a…
Chirality-Induced Spin Selectivity: Nonlinear Spin Response from Electron-Phonon Scattering
Mayank Gupta, Andrew Grieder, Mayada Fadel +4
Chirality-induced spin selectivity (CISS) generates spin-polarized currents in nonmagnetic materials from structural chirality alone, yet its microscopic origin remains debated. Us…
Two-dimensional helical superconductivity and gapless superconducting edge modes in the 1T-WS/2H-WS heterophase bilayer
Xuance Jiang, Jennifer Cano, Yuan Ping +2
We propose a material platform comprised of transition metal dichalcogenide (TMDC) heterostructures to realize the two-dimensional (2D) helical superconductivity with an intrinsic…
Relation of Continuous Chirality Measure to Spin and Orbital Polarization, and Chiroptical Properties in Solids
Andrew Grieder, Shihao Tu, Yuan Ping
Chirality introduces intriguing topological, electronic, and spin-optronic properties to molecules and solids. In this work, we provide a quantitative metric for the degree of chir…
Spatio-temporal spin transport from first principles
Mayada Fadel, Joshua Quinton, Mani Chandra +3
We introduce a computational framework for first-principles density matrix transport within the Wigner function formalism to predict transport of quantum-mechanical degrees of free…
