Geometric Dirac operator on the fuzzy sphere

نویسندگان

چکیده

We construct a Connes spectral triple or `Dirac operator' on the non-reduced fuzzy sphere $C_\lambda[S^2]$ as realised using quantum Riemannian geometry with central metric $g$ of Euclidean signature and its associated Levi-Civita connection. The Dirac operator is characterised uniquely up to unitary equivalence within our geometric setting an assumption that spinor bundle trivial rank 2 basis. has KO dimension 3 in case round metric, essentially recovers previous proposal motivated by rotational symmetry.

The Dirac operator on the fuzzy sphere

We introduce the Fuzzy analog of spinor bundles over the sphere on which the non-commutative analog of the Dirac operator acts. We construct the complete set of eigenstates including zero modes. In the commutative limit we recover known results. *) Part of Project Nr. P8916-PHY of the " Fonds zur Förderung der wissenschaftlichen Forschung in¨Osterreich " .

Dirac operator on the Riemann sphere

We solve for spectrum, obtain explicitly and study group properties of eigenfunc-tions of Dirac operator on the Riemann sphere S 2. The eigenvalues λ are nonzero integers. The eigenfunctions are two-component spinors that belong to representations of SU (2)-group with half-integer angular momenta l = |λ| − 1 2. They form on the sphere a complete orthonormal functional set alternative to convent...

On the Ginsparg-Wilson Dirac operator in the monopole backgrounds on the fuzzy 2-sphere

In the previous papers, we studied the ’t Hooft-Polyakov (TP) monopole configurations in the U(2) gauge theory on the fuzzy 2-sphere, and showed they have nonzero topological charge in the formalism based on the Ginsparg-Wilson (GW) relation. In this paper, we will show an index theorem in the TP monopole background, which is defined in the projected space, and provide a meaning of the projecti...

Quasi-Dirac Operators on the Sphere

We investigate examples of quasi-spectral triples over two-dimensional commutative sphere, which are obtained by modifying the order-one condition. We find quasi-Dirac operators and calculate the index paring with a representant of K-theory class to prove that the quasispectral triples are mutually inequivalent. MSC 2000: 58B34, 46L87, 34L40
