DOI: 10.1038/s42005-019-0273-y
Abstract: Quantum simulators allow to explore static and dynamical properties of otherwise intractable quantum many-body systems. In many instances, however, the read-out limits such quantum simulations. In this work, we introduce an innovative experimental read-out exploiting… read more here.

DOI: 10.1103/physreva.100.022125
Abstract: Studying the zeros of partition functions in the space of complex control parameters allows one to understand formally how critical behavior of a many-body system can arise in the thermodynamic limit despite various no-go theorems… read more here.

DOI: 10.1103/physreva.95.033636
Abstract: The majority of quantum simulators treat simplified one-band strongly correlated models, whereas multiple bands are needed to describe materials with intermediate correlation. We investigate the sensitivity of multiband quantum simulators to: (1) the form of… read more here.

DOI: 10.1103/physrevlett.129.083401
Abstract: Engineering long-range interactions in cold-atom quantum simulators can lead to exotic quantum many-body behavior. Fermionic atoms in ultracold atomic mixtures can act as mediators, giving rise to long-range Ruderman-Kittel-Kasuya-Yosida-type interactions characterized by the dimensionality and… read more here.

DOI: 10.1126/sciadv.aaw9268
Abstract: We demonstrate the preparation of ground states of largely arbitrary Hamiltonians by sympathetic cooling with a single particle. Simulating computationally intractable many-body problems on a quantum simulator holds great potential to deliver insights into physical,… read more here.
