Non-Abelian optical lattices: Anomalous quantum Hall effect and Dirac Fermions
N. Goldman, A. Kubasiak, A. Bermudez +3
We study the properties of an ultracold Fermi gas loaded in an optical square lattice and subjected to an external and classical non-Abelian gauge field. We show that this system c…
Competing many-body interactions in systems of trapped ions
A. Bermudez, D. Porras, M. A. Martin-Delgado
We propose and theoretically analyse an experimental configuration in which lasers induce 3-spin interactions between trapped ions.By properly choosing the intensities and frequenc…
Topology induced anomalous defect production by crossing a quantum critical point
A. Bermudez, D. Patanè, L. Amico +1
We study the influence of topology on the quench dynamics of a system driven across a quantum critical point. We show how the appearance of certain edge states, which fully charact…
A Lorentz Invariant Pairing Mechanism: Relativistic Cooper Pairs
A. Bermudez, M. A. Martin-Delgado
We study a Lorentz invariant pairing mechanism that arises when two relativistic spin-1/2 fermions are subjected to a Dirac string coupling. In the weak coupling regime, we find re…
