Intrinsic Spin Torque Without Spin-Orbit Coupling
Kyoung-Whan Kim, Kyung-Jin Lee, Hyun-Woo Lee +1
We derive an intrinsic contribution to the non-adiabatic spin torque for non-uniform magnetic textures. It differs from previously considered contributions in several ways and can…
Negative Tunneling Magneto-Resistance in Quantum Wires with Strong Spin-Orbit Coupling
Seungju Han, Llorens Serra, Mahn-Soo Choi
We consider a two-dimensional magnetic tunnel junction of the FM/I/QW(FM+SO)/I/N structure, where FM, I and QW(FM+SO) stand for a ferromagnet, an insulator and a quantum wire (QW)…
Impurity cyclotron resonance of anomalous Dirac electrons in graphene
S. C. Kim, S. -R. Eric Yang, A. H. MacDonald
We have investigated a new feature of impurity cyclotron resonances common to various localized potentials of graphene. A localized potential can interact with a magnetic field in…
Coulomb impurity problem of graphene in magnetic fields
S. C. Kim, S. -R. Eric Yang
Analytical solutions of the Coulomb impurity problem of graphene in the absence of a magnetic field show that when the dimensionless strength of the Coulomb potential reaches a…
Atomically thin p-n junctions with van der Waals heterointerfaces
Chul-Ho Lee, Gwan-Hyoung Lee, Arend M. van der Zande +10
Semiconductor p-n junctions are essential building blocks for modern electronics and optoelectronics. In conventional semiconductors, a p-n junction produces depletion regions of f…
Quantum Resistor-Capacitor Circuit with Majorana Fermion Modes in Chiral Topological Superconductor
Minchul Lee, Mahn-Soo Choi
We investigate the mesoscopic resistor-capacitor circuit consisting of a quantum dot coupled to spatially separated Majorana fermion modes in a chiral topological superconductor. W…
Magnon-Mediated Dzyaloshinskii-Moriya Torque in Homogeneous Ferromagnets
Aurelien Manchon, P. Birame Ndiaye, Jung-Hwan Moon +2
In thin magnetic layers with structural inversion asymmetry and spin-orbit coupling, a Dzyaloshinskii-Moriya interaction arises at the interface. When a spin wave current ${\bf j}_…
MoS2 Nanoresonators: Intrinsically Better Than Graphene?
Jin-Wu Jiang, Harold S. Park, Timon Rabczuk
We perform classical molecular dynamics simulations to examine the intrinsic energy dissipation in single-layer MoS nanoresonators, where a point of emphasis is to compare it…
