Dihedral fullerenes of threefold symmetry with and without face spirals
A general geometrical construction for fullerenes of threefold dihedral symmetry is reported and used to Ðnd those 3 , 3h , 3d examples of this symmetry that are without face spirals. The smallest, a 384-atom cage, has its twelve pentagons arranged in 3 three separate crosses of four fully fused rings and has four atoms more than the smallest known non-spirallable fullerene. Another structure, ...

متن کاملSelf-dual Manifolds and Mirror Symmetry for the Quintic Threefold
For all m ≥ 1 we build a two-dimensional family of smooth manifolds of real dimension 3m + 2 and use it to interpolate between the anticanonical family in CP and its mirror dual. The main tool is the notion of self-dual manifold.
متن کاملQuantum Groups and Q-lattices in Phase Space
Quantum groups lead to an algebraic structure that can be realized on quantum spaces. These are noncommutative spaces that inherit a well deened mathematical structure from the quantum group symmetry. In turn such quantum spaces can be interpreted as noncom-mutative connguration spaces for physical systems which carry a symmetry like structure. These connguration spaces will be generalized to n...
متن کاملPhase-Stable Free-Space Optical Lattices for Trapped Ions.
We demonstrate control of the absolute phase of an optical lattice with respect to a single trapped ion. The lattice is generated by off-resonant free-space laser beams, and we actively stabilize its phase by measuring its ac-Stark shift on a trapped ion. The ion is localized within the standing wave to better than 2% of its period. The locked lattice allows us to apply displacement operations ...
