Reflection Positivity for Majorana Fermions    [PDF]

Arthur Jaffe, Fabio L. Pedrocchi

We establish reflection positivity for Gibbs trace states defined by a certain class of Hamiltonians that describe the interaction of Majorana fermions on a lattice. These Hamiltonians may include many-body interactions, as long as the signs of the associated coupling constants satisfy certain restrictions. We show that reflection positivity holds on an even subalgebra of Majorana fermions.
