Shell and axial phases

An armchair carbon nanotube with an endohedral impurity

Many impurities tend to move off the symmetry axis of the nanotube, spontaneously breaking axial symmetry [Phys. Rev. Lett. 90, 035507 (2003)]. At low temperatures, impurities will rotate around the nanotube axis. Such a system is predicted to be a realization of a two-channel Kondo liquid (SU(2)xSU(2)), displaying exotic effects in its electric transport and in its specific heat.
