Direct observation of tensile-strain-induced nanoscale magnetic hardening

Nature Communications, 2023
Magnetoelasticity is the bond between magnetism and mechanics, but the intricate mechanisms via which magnetic states change due to mechanical strain remain poorly understood.

Pseudopotential for the electron-electron interaction [PDF]

Physical Review B, 2015
We propose a pseudopotential for the electron-electron Coulomb interaction to improve the efficiency of many-body electronic structure calculations. The pseudopotential accurately replicates the scattering properties of the Coulomb interaction, and recovers the analytical solution for two electrons in a parabolic trap.

Hydrodynamics of electrons in graphene [PDF]

Journal of Physics: Condensed Matter, 2017
Generic interacting many-body quantum systems are believed to behave as classical fluids on long time and length scales. Due to rapid progress in growing exceptionally pure crystals, we are now able to experimentally observe this collective motion of ...
