Interaction effects on persistent current of ballistic cylindrical nanostructures
We consider clean cylindrical nanostructures with an applied longitudinal static magnetic field. Without Coulomb interaction, the field induces, for particular values, points of degeneracy where a change of ground state takes place due to Aharonov-Bohm effect. The Coulomb potential introduces interaction between the electronic configurations. As a consequence, when there is degeneracy, the grou...
متن کاملAlternating current driven instability in magnetic junctions.
An effect is considered of alternating (high-frequency) current on the spin-valve-type magnetic junction configuration. The stability with respect to small fluctuations is investigated in the macrospin approximation. When the current frequency is close to the eigenfrequency (precession frequency) of the free layer, parametric resonance occurs. Both collinear configurations, antiparallel and par...
متن کاملA cosmic ray current-driven instability in partially ionised media
Context. We investigate the growth of hydromagnetic waves driven by streaming cosmic rays in the precursor environment of a supernova remnant shock. Aims. It is known that transverse waves propagating parallel to the mean magnetic field are unstable to anisotropies in the cosmic ray distribution, and may provide a mechanism to substantially amplify the ambient magnetic field. We quantify the ex...
متن کاملA current driven instability in parallel, relativistic shocks
Abstract. Recently, Bell [2] has reanalysed the problem of wave excitation by cosmic rays propagating in the pre-cursor region of a supernova remnant shock front. He pointed out a strong, non-resonant, current-driven instability that had been overlooked in the kinetic treatments by Achterberg [1] and McKenzie & Völk [10], and suggested that it is responsible for substantial amplification of the...
متن کاملBallistic composite fermions in semiconductor nanostructures.
We report the results of two fundamental transport measurements at a Landau level filling factor ν of 1/2. The well known ballistic electron transport phenomena of quenching of the Hall effect in a mesoscopic cross-junction and negative magnetoresistance of a constriction are observed close to B = 0 and ν = 1/2. The experimental results demonstrate semi-classical charge transport by composite f...
