Nonabelian localization in equivariant K-theory and Riemann-Roch for quotients
Dan Edidin, William Graham
We prove a localization formula in equivariant algebraic -theory for an arbitrary complex algebraic group acting with finite stabilizer on a smooth algebraic space. This extends…
Magnetic Moment Oscillations in a Quantum Hall Ring
Lachezar S. Georgiev, Michael R. Geller
We predict non-mesoscopic oscillations in the orbital magnetic moment of a thin semiconductor ring in the quantum Hall effect regime. These oscillations, which occur as a function…
Spin structure of spin-1/2 baryon and spinless meson production amplitudes in photo and hadronic reactions
K. Nakayama, W. G. Love
The most general spin structures of the spin-1/2 baryon and spinless meson production operator for both photon and nucleon induced reactions are derived from the partial-wave expan…
Toric degenerations of spherical varieties
Valery Alexeev, Michel Brion
We prove that any affine, resp. polarized projective, spherical variety admits a flat degeneration to an affine, resp. polarized projective, toric variety. Motivated by Mirror Symm…
The anisotropic quantum antiferromagnet on the Sierpinski gasket: Ground state and thermodynamics
Andreas Voigt, Wolfgang Wenzel, Johannes Richter +1
We investigate an antiferromagnetic s=1/2 quantum spin system with anisotropic spin exchange on a fractal lattice, the Sierpinski gasket. We introduce a novel approximative numeric…
