Graph Partitioning into Hamiltonian Subgraphs on a Quantum Annealer
Eugenio Cocchi, Edoardo Tignone, Davide Vodola
We demonstrate that a quantum annealer can be used to solve the NP-complete problem of graph partitioning into subgraphs containing Hamiltonian cycles of constrained length. We pre…
Coherent Manipulation of Spin Correlations in the Hubbard Model
N. Wurz, C. F. Chan, M. Gall +6
We coherently manipulate spin correlations in a two-component atomic Fermi gas loaded into an optical lattice using spatially and time-resolved Ramsey spectroscopy combined with hi…
Measuring entropy and mutual information in the two-dimensional Hubbard model
E. Cocchi, L. A. Miller, J. H. Drewes +4
We measure pressure and entropy of ultracold fermionic atoms in an optical lattice for a range of interaction strengths, temperatures and fillings. Our measurements demonstrate tha…
Antiferromagnetic correlations in two-dimensional fermionic Mott-insulating and metallic phases
J. H. Drewes, L. A. Miller, E. Cocchi +4
Near zero temperature, quantum magnetism can non-trivially arise from short-range interactions, but the occurrence of magnetic order depends crucially on the interplay of interacti…
Thermodynamics vs. local density fluctuations in the metal/Mott-insulator crossover
J. H. Drewes, E. Cocchi, L. A. Miller +4
The crossover between a metal and a Mott insulator leads to a localization of fermions from delocalized Bloch states to localized states. We experimentally study this crossover usi…
Equation of state of the two-dimensional Hubbard model
Eugenio Cocchi, Luke A. Miller, Jan H. Drewes +4
Understanding the phases of strongly correlated quantum matter is challenging because they arise from the subtle interplay between kinetic energy, interactions, and dimensionality.…
Relaxation dynamics of a Fermi gas in an optical superlattice
D. Pertot, A. Sheikhan, E. Cocchi +5
This paper comprises an experimental and theoretical investigation of the time evolution of a Fermi gas following fast and slow quenches of a one-dimensional optical double-well su…
