Distinct multiple fermionic states in a single topological metal
M. Mofazzel Hosen, Klauss Dimitri, Ashis K. Nandy +11
Among the quantum materials that gained interest recently are the topological Dirac/Weyl semimetals, where conduction and valence bands touch at points in reciprocal (k)-space, and…
Generation of single skyrmions by picosecond magnetic field pulses
Vegard Flovik, Alireza Qaiumzadeh, Ashis K. Nandy +2
We numerically demonstrate an ultrafast method to create skyrmions in a ferromagnetic sample by applying a picosecond (effective) magnetic fi…
Switching of chiral magnetic skyrmions by picosecond magnetic field pulses via transient topological states
Changhoon Heo, Nikolai S. Kiselev, Ashis Kumar Nandy +2
Magnetic chiral skyrmions are vortex like spin structures that appear as stable or meta-stable states in magnetic materials due to the interplay between the symmetric and antisymme…
