Skyrmions Near Defects
Amel Derras-Chouk, Eugene M. Chudnovsky
We study the impact of an exchange-reducing defect on a skyrmion for a thin film of finite thickness. Attraction of the skyrmion to a defect is demonstrated in a lattice model by c…
Skyrmions in an oblique field: A path to novel binary and quaternary memory
Daniel Capic, Dmitry A. Garanin, Eugene M. Chudnovsky
We propose a novel binary and quaternary memory device based upon skyrmion states induced by the oblique field in a square magnetic island. To describe stable states and dynamics o…
Skyrmion Mass from Spin-Phonon Interaction
D. Capic, E. M. Chudnovsky, D. A. Garanin
Inertial mass of a skyrmion arising from spin-phonon interaction is computed exactly within a toy model of the magnetoelastic coupling in a ferromagnetic film. The mass scales as t…
A physicist view of COVID-19 airborne infection through convective airflow in indoor spaces
Luis A. Anchordoqui, Eugene M. Chudnovsky
[Abridged] Naturally produced droplets from humans (such as those produced by breathing, talking, sneezing, and coughing) include several types of cells (e.g., epithelial cells and…
Skyrmion-Skyrmion Interaction in a Magnetic Film
Daniel Capic, D. A. Garanin, E. M. Chudnovsky
Interaction of two skyrmions stabilized by the ferromagnetic exchange, Dzyaloshinskii-Moriya interaction (DMI), and external magnetic field has been studied numerically on a 2D lat…
