Emergence and suppression of phonon vortices in two-dimensional crystals: Interplay of lattice symmetry, heavy impurities, and shear
Yu-Tian Zhang, Deng Pan, Yuliang Jin
Phonon vortices are vortex-like displacement fields that appear in the vibrational modes of two- dimensional materials. Here, we demonstrate that these vortices arise as symmetry-a…

Shear Banding in Amorphous Solids as a Nonlinear Screened Soft Mode Instability
Yang Fu, Yuliang Jin, Avanish Kumar +1
Shear banding is a well-known and widespread instability in strained solids: under external strain, the deformation localizes along a line in two dimensions or a plane in three dim…
