Quantization of pencils with a gl-type Poisson center and braided geometry

Dimitri Gurevich, Pavel Saponov (2011)

Banach Center Publications

We consider Poisson pencils, each generated by a linear Poisson-Lie bracket and a quadratic Poisson bracket corresponding to a so-called Reflection Equation Algebra. We show that any bracket from such a Poisson pencil (and consequently, the whole pencil) can be restricted to any generic leaf of the Poisson-Lie bracket. We realize a quantization of these Poisson pencils (restricted or not) in the framework of braided affine geometry. Also, we introduce super-analogs of all these Poisson pencils and...

Quantum Equivalent Magnetic Fields that Are Not Classically Equivalent

Carolyn Gordon, William Kirwin, Dorothee Schueth, David Webb (2010)

Annales de l’institut Fourier

We construct pairs of compact Kähler-Einstein manifolds ( M i , g i , ω i ) ( i = 1 , 2 ) of complex dimension n with the following properties: The canonical line bundle L i = n T * M i has Chern class [ ω i / 2 π ] , and for each positive integer k the tensor powers L 1 k and L 2 k are isospectral for the bundle Laplacian associated with the canonical connection, while M 1 and M 2 – and hence T * M 1 and T * M 2 – are not homeomorphic. In the context of geometric quantization, we interpret these examples as magnetic fields which are quantum equivalent but not classically equivalent....
