A relation between moduli space of D-branes on orbifolds and Ising model
نویسنده
چکیده
We study D-branes transverse to an abelian orbifold C/Zn × Zn. The moduli space of the gauge theory on the D-branes is analyzed by combinatorial calculation based on toric geometry. It is shown that the calculation is related to a problem to count the number of ground states of an antiferromagnetic Ising model. The lattice on which the Ising model is defined is a triangular one defined on the McKay quiver of the orbifold.

D-geometric structure of orbifolds
We study D-branes on abelian orbifolds C/ZN for d = 2, 3. The toric data describing the D-brane vacuum moduli space, which represents the geometry probed by D-branes, has certain redundancy compared with the classical geometric description of the orbifolds. We show that the redundancy has a simple combinatorial structure and find analytic expressions for degrees of the redundancy. For d = 2 the...
متن کاملA Ricci-flat metric on D-brane orbifolds
We study issues pertaining to the Ricci-flatness of metrics on orbifolds resolved by Dbranes. We find a Kähler metric on the three-dimensional orbifold C/Z3, resolved by D-branes, following an approach due to Guillemin. This metric is not Ricci-flat for any finite value of the blow-up parameter. Conditions for the envisaged Ricci-flat metric for finite values of the blow-up parameter are formul...
متن کاملD-branes on Orbifolds and Topology Change
We consider D-branes on an orbifold C/Zn and investigate the moduli space of the D-brane world-volume gauge theory by using toric geometry and gauged linear sigma models. For n = 11, we find that there are five phases which are topologically distinct and connected by flops to each other. We also verify that non-geometric phases are projected out for n = 7, 9, 11 cases as expected. Resolutions o...
متن کاملD-branes and Discrete Torsion II
We derive D-brane gauge theories for C/ZZn ×ZZn orbifolds with discrete torsion and study the moduli space of a D-brane at a point. We show that, as suggested in previous work, closed string moduli do not fully resolve the singularity, but the resulting space – containing n − 1 conifold singularities – is somewhat surprising. Fractional branes also have unusual properties. We also define an ind...
متن کاملFractional Branes and Boundary States in Orbifold Theories
We study the D-brane spectrum of N = 2 string orbifold theories using the boundary state formalism. The construction is carried out for orbifolds with isolated singularities, non-isolated singularities and orbifolds with discrete torsion. Our results agree with the corresponding K-theoretic predictions when they are available and generalize them when they are not. This suggests that the classif...
