Product Vacua and Boundary State Models in d Dimensions
Sven Bachmann, Eman Hamza, Bruno Nachtergaele +1
We introduce and analyze a class of quantum spin models defined on d-dimensional lattices Lambda subset of Z^d, which we call `Product Vacua with Boundary States' (PVBS). We charac…

Spectral Properties of Non-Unitary Band Matrices
Eman Hamza, Alain Joye
We consider families of random non-unitary contraction operators defined as deformations of CMV matrices which appear naturally in the study of random quantum walks on trees or lat…
