Manipulating Quantum Spins by a Spin-Polarized Current: An Approach Based Upon PT-Symmetric Quantum Mechanics
Aleix Bou Comas, Eugene M. Chudnovsky, Javier Tejada
We propose a quantum processor based upon single-molecule magnets and spin transfer torque described by PT-symmetric quantum mechanics. In recent years PT-symmetric Hamiltonians ha…
Thermally assisted skyrmions creation in Pt/Co/Ta multilayer films
Senfu Zhang, Junwei Zhang, Yan Wen +2
Néel-type magnetic skyrmions in multilayer films have attracted significant amount of attention recently for their stability at room temperature and capability of motion driven by…
Writing Skyrmions with a Magnetic Dipole
Dmitry A. Garanin, Daniel Capic, Senfu Zhang +2
We demonstrate numerically on large spin lattices that one can write skyrmions in a thin magnetic film with a magnetic dipole of a few tens of nanometer in size. Nucleation of non-…
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…
Determination of chirality and density control of Néel-type skyrmions with in-plane magnetic field
Senfu Zhang, Junwei Zhang, Yan Wen +2
Magnetic skyrmions are topologically protected nanoscale spin textures exhibiting fascinating physical behaviors. Recent observations of room temperature Néel-type skyrmions in mag…
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…
