Journal ArticleDOI
Symmetry-induced formation of antivortices in mesoscopic superconductors.
TL;DR: It is shown that additional vortex–antivortex pairs nucleate spontaneously so as to preserve the symmetry of the sample, and symmetry-induced nucleation of antivortices is not restricted to superconductors, but should also apply to symmetrically confined superfluids and Bose–Einstein condensates.
Journal ArticleDOI
Electron Deficiency of the Fullerenes
P.W. Fowler,Arnout Ceulemans +1 more
TL;DR: In this paper, a qualitative molecular-orbital treatment and group-theoretical analysis of closed-shell fullerenes has been performed and it has been shown that C[sub 60] and all the other closedshell closed shells of the infinite leapfrog class have six lowlying empty orbitals matching the translational and rotational symmetries.
Journal ArticleDOI
Magnetic dipole transitions as standards for Judd–Ofelt parametrization in lanthanide spectra
TL;DR: In this paper, it was shown that the sum of the intensities for magnetic dipole transitions between crystal-field components of two free ion levels in lanthanide spectra is almost independent of the symmetry of the environment.
Journal ArticleDOI
Mechanism of a strongly anisotropic MoIII-CN-MnII spin-spin coupling in molecular magnets based on the [Mo(CN)(7)](4-) heptacyanometalate: a new strategy for single-molecule magnets with high blocking temperatures.
TL;DR: It is indicated that highly anisotropic spin-spin couplings combined with large exchange parameters represent a very important source of the global magnetic anisotropy of polyatomic molecular magnetic clusters.
Journal ArticleDOI
Electronic Structures and Geometries of C60 Anions via Density Functional Calculations
William H. Green,Sergiu M. Gorun,George Fitzgerald,Patrick W. Fowler,Arnout Ceulemans,Bruno C. Titeca +5 more
TL;DR: In this paper, the electronic structures of C60 and its mono-through hexaanions, all of which have been prepared in macroscopic quantities, are calculated using modern density functional techniques.
