Lifetime of double occupancies in the Fermi-Hubbard model
Rajdeep Sensarma, David Pekker, Ehud Altman +7
We investigate the decay of artificially created double occupancies in a repulsive Fermi-Hubbard system in the strongly interacting limit using diagrammatic many-body theory and ex…
Quantitative Determination of Temperature in the Approach to Magnetic Order of Ultracold Fermions in an Optical Lattice
Robert Jördens, Leticia Tarruell, Daniel Greif +12
We perform a quantitative simulation of the repulsive Fermi-Hubbard model using an ultracold gas trapped in an optical lattice. The entropy of the system is determined by comparing…
Observation of Elastic Doublon Decay in the Fermi-Hubbard Model
Niels Strohmaier, Daniel Greif, Robert Jördens +7
We investigate the decay of highly excited states of ultracold fermions in a three-dimensional optical lattice. Starting from a repulsive Fermi-Hubbard system near half filling, we…
A Mott insulator of fermionic atoms in an optical lattice
Robert Jördens, Niels Strohmaier, Kenneth Günter +2
In a solid material strong interactions between the electrons can lead to surprising properties. A prime example is the Mott insulator, where the suppression of conductivity is a r…
Interaction-controlled transport of an ultracold Fermi gas
Niels Strohmaier, Yosuke Takasu, Kenneth Günter +4
We explore the transport properties of an interacting Fermi gas in a three-dimensional optical lattice. The center of mass dynamics of the atoms after a sudden displacement of the…
