The Index and Axial Anomaly of a Lattice Dirac Operator
A remarkable feature of a lattice Dirac operator is discussed. Unlike the Dirac operator for massless fermions in the continuum, this Ginsparg-Wilson lattice Dirac operator does not possess topological zero modes for any topologically-nontrivial background gauge fields, even though it is exponentially-local, doublers-free, and reproduces correct axial anomaly for topologically-trivial gauge con...
متن کاملAn index theorem for Toeplitz operators on odd-dimensional manifolds with boundary
We establish an index theorem for Toeplitz operators on odd-dimensional spin manifolds with boundary. It may be thought of as an odd-dimensional analogue of the Atiyah–Patodi–Singer index theorem for Dirac operators on manifolds with boundary. In particular, there occurs naturally an invariant of η type associated to K1 representatives on even-dimensional manifolds, which should be of independe...
متن کاملAn index theorem for families of Dirac operators on odd-dimensional manifolds with boundary
For a family of Dirac operators acting on Hermitian Cli ord modules over the odd dimensional compact manifolds with boundary which are the bres of a bration with compact base we compute the Chern character of the index in K of the base Although we assume a product decomposition near the boundary we make no assumptions on invertibility of the bound ary family and instead obtain a family of self ...
متن کاملAnomaly Cancellation in Seven-Dimensional Supergravity with a Boundary
We construct a seven-dimensional brane world in a slice of AdS7, where the boundary matter content is fixed by the cancellation of anomalies. The seven-dimensional minimal N = 2 gauged supergravity is compactified on the orbifold S/Z2, and the supersymmetric bulk-boundary Lagrangian is consistently derived for boundary vector and hypermultipets up to fermionic bilinear terms. Anomaly cancellati...
متن کاملChiral Anomaly and Index Theorem on a finite lattice
The condition for a lattice Dirac operator D to reproduce correct chiral anomaly at each site of a finite lattice for smooth background gauge fields is that D possesses exact zero modes satisfying the Atiyah-Singer index theorem. This is also the necessary condition for D to have correct fermion determinant ( ratio ) which plays the important role of incorporating dynamical fermions in the func...
