Regular and in-plane skyrmions and antiskyrmions from boundary instabilities
Shane Sandhoefner, Aldo Raeliarijaona, Rabindra Nepal +2
We formulate a theory of skyrmion and antiskyrmion generation using magnetic field and charge current pulses. We show that the topological defect can be created at an edge of a sys…
Valley-dependent Lorentz force and Aharonov-Bohm phase in strained graphene p-n junction
Sanjay Prabhakar, Rabindra Nepal, Roderick Melnik +1
Veselago lens focusing in graphene p-n junction is promising for realizations of new generation electron optics devices. However, the effect of the strain-induced Aharonov-Bohm int…
Boundary twists, instabilities, and creation of skyrmions and antiskyrmions
Aldo Raeliarijaona, Rabindra Nepal, Alexey A. Kovalev
We formulate and study the general boundary conditions dictating the magnetization profile in the vicinity of an interface between magnets with dissimilar properties. Boundary twis…
Magnetic skyrmion bubble motion driven by surface acoustic waves
Rabindra Nepal, Utkan Güngördü, Alexey A. Kovalev
We study the dynamical control of a magnetic skyrmion bubble by using counter-propagating surface acoustic waves (SAWs) in a ferromagnet. First, we determine the bubble mass and de…
Stability of skyrmion lattices and symmetries of quasi-two-dimensional chiral magnets
Utkan Güngördü, Rabindra Nepal, Oleg A. Tretiakov +2
Recently, there has been substantial interest in realizations of skyrmions, in particular in 2D systems due to increased stability resulting from reduced dimensionality. A stable s…
Parafermion stabilizer codes
Utkan Güngördü, Rabindra Nepal, Alexey A. Kovalev
We define and study parafermion stabilizer codes which can be viewed as generalizations of Kitaev's one dimensional model of unpaired Majorana fermions. Parafermion stabilizer code…
