Quantum Simulation Meets Nonequilibrium Dynamical Mean Field Theory: Exploring the Periodically Driven, Strongly Correlated Fermi-Hubbard Model
Kilian Sandholzer, Yuta Murakami, Frederik Görg +6
We perform an ab-initio comparison between nonequilibrium dynamical mean-field theory and optical lattice experiments by studying the time evolution of double occupations in the pe…
Observation of two-beam collective scattering phenomena in a Bose-Einstein condensate
Ivana Dimitrova, William Lunden, Jesse Amato-Grill +7
New phenomena of collective light scattering are observed when an elongated Bose-Einstein condensate is pumped by two non-interfering beams counterpropagating along its long axis.…
Controlling the Floquet state population and observing micromotion in a periodically driven two-body quantum system
Rémi Desbuquois, Michael Messer, Frederik Görg +3
Near-resonant periodic driving of quantum systems promises the implementation of a large variety of novel effective Hamiltonians. The challenge of Floquet engineering lies in the p…
Multiscale change point detection via gradual bandwidth adjustment in moving sum processes
Tijana Levajkovic, Michael Messer
A method for the detection of changes in the expectation in univariate sequences is provided. Moving sum processes are studied. These rely on the selection of a tuning bandwidth. H…
Multi-scale detection of rate changes in spike trains with weak dependencies
Michael Messer, Kauê M. Costa, Jochen Roeper +1
The statistical analysis of neuronal spike trains by models of point processes often relies on the assumption of constant process parameters. However, it is a well-known problem th…
Formation and dynamics of anti-ferromagnetic correlations in tunable optical lattices
Daniel Greif, Gregor Jotzu, Michael Messer +2
We report on the observation of anti-ferromagnetic correlations of ultracold fermions in a variety of optical lattice geometries that are well described by the Hubbard model, inclu…
