Skyrmions in 2D chiral magnets with noncollinear ground states stabilized by higher-order interactions
Mathews Benny, Moinak Ghosh, Moritz A. Goerzen +4
Magnetic skyrmions are intriguing topological spin textures that have attracted great attention due to their potential for future spintronic devices. Skyrmions have so far been exp…
Platform for zero-field isolated skyrmions: 4/Co atomic bilayers on Re(0001)
Moinak Ghosh, Stefan Heinze, Souvik Paul
Using first-principles density functional theory (DFT) combined with atomistic spin simulations, we explore the possibility of realizing zero-field isolated skyrmions in three 4…
Optimized Sparse Network Coverage via L1-norm Minimization
Souvik Paul, Iván Alexander Morales Sandoval, Giuseppe Thadeu Freitas de Abreu
The selection of nodes that can serve as cluster heads, local sinks and gateways is a critical challenge in distributed sensor and communication networks. This paper presents a nov…
Tuning magnetic interactions of Co and 4 transition-metal atomic bilayers on Re(0001) via interface engineering
Souvik Paul, Stefan Heinze
Employing density functional theory (DFT), we performed a systematic investigation of the electronic structures and the magnetic properties of atomic bilayers…
