Enhanced pairing mechanism in Cuprate-type crystals
Maximilian Duell, Christian Hainzl, Eman Hamza
Using a BCS mean-field approach, we show how the interplay between low-momentum optical phonons and Jahn-Teller-type lattice distortions can open an attractive channel that allows…
Thermalization of Fermionic Quantum Walkers
Eman Hamza, Alain Joye
We consider the discrete time dynamics of an ensemble of fermionic quantum walkers moving on a finite discrete sample, interacting with a reservoir of infinitely many quantum parti…
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…
Spectral Transition for Random Quantum Walks on Trees
Eman Hamza, Alain Joye
We define and analyze random quantum walks on homogeneous trees of degree . Such walks describe the discrete time evolution of a quantum particle with internal degree of f…
Correlated Markov Quantum Walks
Eman Hamza, Alain Joye
We consider the discrete time unitary dynamics given by a quantum walk on performed by a particle with internal degree of freedom, called coin state, according to the follow…
