Hidden Magnon Berry Curvature drives Vertical Magnon Transport
Atul Rathor, Sahanawaj Akhtar, Arijit Haldar
We predict an in-plane, or hidden, Berry curvature (BC) for magnons in electrically insulating quasi-2D magnets and demonstrate that the hidden magnon Berry curvature (HMBC) gives…

Spin Injection Route to Magnon Berry Curvature Dipole
Atul Rathor, Saurav Kantha, Arijit Haldar
Berry curvature of Bloch bands arising in lattice systems can induce a Hall response even in the absence of topology due to the so-called Berry-curvature dipole (BCD). Such a respo…
