Quantum States of a Skyrmion in a 2D Antiferromagnet
A. Derras-Chouk, E. M. Chudnovsky, D. A. Garanin
Quantum states of a skyrmion in a 2D antiferromagnetic lattice are obtained by quantizing the scaling parameter of Belavin-Polyakov model. Skyrmion classical collapse due to violat…

Thermal Collapse of a Skyrmion
Amel Derras-Chouk, Eugene M. Chudnovsky, Dmitry A. Garanin
Thermal collapse of an isolated skyrmion on a two-dimensional spin lattice has been investigated. The method is based upon solution of the system of stochastic Landau-Lifshitz-Gilb…

Quantum Collapse of a Magnetic Skyrmion
Amel Derras-Chouk, Eugene M. Chudnovsky, Dmitry A. Garanin
Quantum collapse of a small skyrmion in a thin magnetic film with Dzyalishinskii-Moriya (DMI) interaction has been studied. The energy of the skyrmion and the stability threshold d…
