Force and impulse from an Aharonov–Bohm flux line
We calculate the force operator for a charged particle in the field of an Aharonov–Bohm flux line. Formally this is the Lorentz force, with the magnetic field operator modified to include quantum corrections due to anomalous commutation relations. For stationary states, the magnitude of the force is proportional to the product of the wavenumber k with the amplitudes of the ‘pinioned’ components...
متن کاملForce and impulse from an Aharonov - Bohm ux line [
We calculate the force operator for a charged particle in the eld of an Aharonov-Bohm ux line. Formally this is the Lorentz force, with the magnetic eld operator modiied to include quantum corrections due to anomolous commutation relations. For stationary states, the magnitude of the force is proportional to the product of the wavenumber k with the amplitudes of thèpinioned' components, the two...
متن کاملNonequilibrium work statistics of an Aharonov-Bohm flux.
We investigate the statistics of work performed on a noninteracting electron gas confined in a ring as a threaded magnetic field is turned on. For an electron gas initially prepared in a grand canonical state it is demonstrated that the Jarzynski equality continues to hold in this case, with the free energy replaced by the grand potential. The work distribution displays a marked dependence on t...
متن کاملMagnus Force and Aharonov-Bohm Effect in Superfluids
The paper addresses the problem of the transverse force (Magnus force) on a vortex in a Galilean invariant quantum Bose liquid. Interaction of quasiparticles (phonons) with a vortex produces an additional transverse force (Iordanskii force). The Iordanskii force is related to the acoustic Aharonov–Bohm effect. Connection of the effective Magnus force with the Berry phase is also discussed.
متن کاملConductivity in Carbon Nanotubes with Aharonov–Bohm Flux
The Boltzmann conductivity is calculated for carbon nanotubes in the presence of an Aharonov–Bohm magnetic flux. Effects of impurity scattering are considered at low temperatures and those of electron– phonon scattering are considered at room temperature. Effects of strains and curvature manifest themselves as a prominent conductivity peak as a function of the flux. The appearance of the peak c...
