Dynamics of the collapse of a ferromagnetic skyrmion in a centrosymmetric lattice
A. Derras-Chouk, E. M. Chudnovsky, D. A. Garanin
Time dependence of the size and chirality of a ferromagnetic skyrmion in a Heisenberg model with the magnetic field on a square lattice has been studied analytically and numericall…
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…
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…
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…
Graphene Cantilever Under Casimir Force
Amel Derras-Chouk, Eugene Chudnovsky, Dmitry Garanin +1
Stability of graphene cantilever under Casimir attraction to an underlying conductor is investigated. The dependence of the instability threshold on temperature and flexural rigidi…
