Topological phases of lattice bosons with a dynamical gauge field
David Raventós, Tobias Graß, Bruno Juliá-Díaz +2
Optical lattices with a complex-valued tunnelling term have become a standard way of studying gauge-field physics with cold atoms. If the complex phase of the tunnelling is made de…
Dual trapped-ion quantum simulators: an alternative route towards exotic quantum magnets
Tobias Graß, Maciej Lewenstein, Alejandro Bermudez
We present a route towards the quantum simulation of exotic quantum magnetism in ion traps by exploiting dual relations between different spin models. Our strategy allows one to st…
Quench dynamics of dipolar fermions in a one-dimensional harmonic trap
Tobias Graß
We study a system of few fermions in a one-dimensional harmonic trap, and focus on the case of dipolar majority particles in contact with a single impurity. The impurity is used bo…
Quantum annealing for the number partitioning problem using a tunable spin glass of ions
Tobias Graß, David Raventós, Bruno Juliá-Díaz +2
Exploiting quantum properties to outperform classical ways of information-processing is an outstanding goal of modern physics. A promising route is quantum simulation, which aims a…
Entanglement and Nonlocality in Many-Body Systems: a primer
J. Tura, A. B. Sainz, T. Grass +3
Current understanding of correlations and quantum phase transitions in many-body systems has significantly improved thanks to the recent intensive studies of their entanglement pro…
