Observation of Wigner cusps in a metallic carbon nanotube
B. T. Blue, R. Tsuchikawa, A. Ahmadi +6
Previous gate-dependent conductance measurements of metallic carbon nanotubes have revealed unexplainable conductance suppressions, occurring at two different gate voltages. These…
A microscopic formulation of dynamical spin injection in ferromagnetic-nonmagnetic heterostructures
Amin Ahmadi, Eduardo R. Mucciolo
We develop a microscopic formulation of dynamical spin injection in heterostructure comprising nonmagnetic metals in contact with ferromagnets. The spin pumping current is expresse…
Dynamical spin injection at a quasi-one-dimensional ferromagnet-graphene interface
S. Singh, A. Ahmadi, C. T. Cherian +3
We present a study of dynamical spin injection from a three-dimensional ferromagnet into two-dimensional single-layer graphene. Comparative ferromagnetic resonance (FMR) studies of…
Exact solutions of Dirac equation on (1+1)-dimensional spacetime coupled to a static scalar field
F. Darabi, S. K. Moayedi, A. R. Ahmadi
We use a generalized scheme of supersymmetric quantum mechanics to obtain the energy spectrum and wave function for Dirac equation in (1+1)-dimensional spacetime coupled to a stati…
