Semiclassical approach to finite temperature quantum annealing with trapped ions
David Raventós, Tobias Graß, Bruno Juliá-Díaz +1
Recently it has been demonstrated that an ensemble of trapped ions may serve as a quantum annealer for the number-partitioning problem [Nature Comm. DOI: 10.1038/ncomms11524]. This…
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…
Cold bosons in optical lattices: a tutorial for Exact Diagonalization
David Raventós, Tobias Graß, Maciej Lewenstein +1
Exact diagonalization techniques are a powerful method for studying many-body problems. Here, we apply this method to systems of few bosons in an optical lattice, and use it to dem…
Quantum Hall phases of two-component bosons
Tobias Graß, David Raventós, Maciej Lewenstein +1
The recent production of synthetic magnetic fields acting on electroneutral particles, like atoms or photons, has boosted the interest in the quantum Hall physics of bosons. Adding…
