Scharf, Benedikt and Fabian, Jaroslav and Matos-Abiague, Alex (2010) Theory of pseudospin excitations in coaxial nanotubes. Phys. Rev. B 81 (12), p. 125428.
In two-dimensional electron gases confined to two coaxial tubes the "tube degree of freedom" can be described in terms of pseudospin-1/2 dynamics. The presence of tunneling between the two tubes leads to a collective oscillation known as pseudospin resonance. We employ perturbation theory to examine the dependence of the frequency of this mode with respect to a coaxial magnetic field for the case ...
