When electrons pass through a cylindrical electrical conductor aligned in a magnetic field, their wave-like nature manifests itself as a periodic oscillation in the electrical resistance as a function of the enclosed magnetic flux. This phenomenon reflects the dependence of the phase of the electron wave on the magnetic field, known as the Aharonov–Bohm effect, which causes a phase difference, and hence interference, between partial waves encircling the conductor in opposite directions. Such… 
Anomalous aharonov-bohm gap oscillations in carbon nanotubes.
Curvature effects and electronic density that is spilled out of the nanotube surface are shown to break the periodicity of the gap oscillations and the key phenomenological features of this anomalous Aharonov-Bohm effect in semiconductive and metallic tubes are predicted.
Aharonov–Bohm differential conductance modulation in defective metallic single-walled carbon nanotubes
Using a perturbative approach, the effects of the energy gap induced by the Aharonov–Bohm (AB) flux on the transport properties of defective metallic single-walled carbon nanotubes (MSWCNTs) are

Magnetoresistance devices based on single-walled carbon nanotubes.
The physical principles for the construction of a nanometer-sized magnetoresistance device based on the Aharonov-Bohm effect are demonstrated and it is shown that by retracting the tip/contacts, so that the coupling to the SWCNT is reduced, very high sensitivity to the threading magnetic field develops.

The magnetic response of electrons in a zigzag carbon nanotube (CN) threaded by an Aharonov Bohm flux φ is carefully analyzed by using a Hartree Fock approximation. The ground state energy as a

Single-walled carbon nanotubes (SWNTs) present an ideal system for study of one dimensional physics. Classically speaking, their long persistence lengths result in rigid-rod-like behavior in the

It is demonstrated experimentally and theoretically that, in carbon nanotube quantum dots combining cylindrical topology and bipartite hexagonal lattice, a magnetic field along the nanotubes axis impacts also the longitudinal profile of the electronic states.

The electrical properties of individual bundles, or “ropes,” of single-walled carbon nanotubes have been measured, and dramatic peaks were observed in the conductance as a function of a gate voltage that modulated the number of electrons in the rope.
Atomic structure and electronic properties of single-walled carbon nanotubes
Carbon nanotubes are predicted to be metallic or semiconducting depending on their diameter and the helicity of the arrangement of graphitic rings in their walls. Scanning tunnelling microscopy (STM)

The temperature dependence of both the amplitude of the oscillations and the background are consistent with the recent theory by Stone, while the background structure was not symmetric about zero field.
