Achieving Large Uniaxial and Homogeneous Strain in Two-Dimensional Materials
Yangchen He, Jessica Kienbaum, Wuzhang Fang +4
Strain engineering is a powerful tool for tuning the electronic, magnetic, and topological properties of two-dimensional (2D) materials and thin films - particularly at high values…
Electrically switchable ferron upconversion in a van der Waals ferroelectric
Sujan Subedi, Wuzhang Fang, Fan Fei +7
Nonlinear phononics provides a powerful ultrafast route to control lattice excitations, enabling access to hidden quantum orders, phononic computing, and quantum transduction. Howe…
Unconventional superlattice ordering in intercalated transition metal dichalcogenide VNbS
Shannon S. Fender, Noah Schnitzer, Wuzhang Fang +11
The interplay between symmetry and topology in magnetic materials makes it possible to engineer exotic phases and technologically useful properties. A key requirement for these pur…
Spin non-Collinear Real-Time Time-Dependent Density-Functional Theory and Implementation in the Modern GPU-Accelerated INQ code
Jacopo Simoni, Xavier Andrade, Wuzhang Fang +4
Time-dependent density functional theory (TDDFT) is a theory that describes the time evolution of quantum mechanical many-electron systems under the influence of external time-depe…
Efficient method for calculating magnon-phonon coupling from first principles
Wuzhang Fang, Jacopo Simoni, Yuan Ping
Linear magnon-phonon coupling hybridizes magnon and phonon bands at the same energy and momentum, resulting in an anticrossing signature.This hybrid quasiparticle benefits from a l…
Spin-orbit torque in a three-fold-symmetric bilayer and its effect on magnetization dynamics
Wuzhang Fang, Edward Schwartz, Alexey A. Kovalev +1
Field-free switching of perpendicular magnetization has been observed in an epitaxial L1-ordered CoPt/CuPt bilayer and attributed to spin-orbit torque (SOT) arising from the cr…
