TL;DR: This work demonstrates that in a trapped ion setup, with present day technology, it is possible to realize a spin model of the Mattis-type that exhibits spin glass phases by controlling the detuning of the spin-phonon coupling.

TL;DR: In this paper, the authors apply the exact diagonalization (ED) technique to systems of few bosons in an optical lattice, and use it to demonstrate the emergence of interesting quantum phenomena such as fragmentation and coherence.

TL;DR: Exact diagonalization techniques are a powerful method for studying many-body problems as mentioned in this paper, and they apply this method to systems of few bosons in an optical lattice, and use it to demonstrate the emergence of interesting quantum phenomena like fragmentation and coherence.

TL;DR: In this article, the authors studied the scenario of a few bosons in either a static or a dynamical gauge field by means of exact diagonalization, and the topological structures were identified computing their Chern number.

TL;DR: In this paper, the role played by thermal phonons in a trapped-ion annealer for number partitioning is investigated, and the authors use a semiclassical approach to characterize how the quantum device approaches a solution of an otherwise difficult to solve NP-hard problem.
