We study the anomaly induced effects of dense baryonic matter under rotation. We derive the anomalous terms that account for the chiral vortical effect in the low-energy effective theory for light Nambu-Goldstone modes. The anomalous terms lead to new physical consequences, such as the anomalous Hall energy current and spontaneous generation of angular momentum in a magnetic field (or spontaneous magnetization by rotation). In particular, we show that, due to the presence of such anomalous terms, the ground state of the quantum chromodynamics (QCD) under sufficiently fast rotation becomes the "chiral soliton lattice" of neutral pions that has lower energy than the QCD vacuum and nuclear matter. We briefly discuss the possible realization of the chiral soliton lattice induced by a fast rotation in noncentral heavy ion collisions.

Here, we report the successful direct observation of the smallest free-standing single-walled carbon nanotube, which has a diameter of about 0.43 nm. Our single-walled carbon nanotubes were produced by the improved floating reactant method, which combines the conventional substrate and floating catalyst methods using zeolite particles as a floating catalyst support. This finding is also important because smalldiameter nanotubes were proved to be able to grow without any confinement that limits the tube diameter such as in the tube growth in a template or in the central core of a multiwalled nanotube, as reported in previous studies by other groups. The success of obtaining very small single-walled carbon nanotubes opens the door to unprecedented applications of this fascinating material as a true 1D material.
