Many-body spin rotation by adiabatic passage in spin-1/2 XXZ chains of ultracold atoms
Ivana Dimitrova, Stuart Flannigan, Yoo Kyung Lee +6
Quantum many-body phases offer unique properties and emergent phenomena, making them an active area of research. A promising approach for their experimental realization in model sy…
Transverse spin dynamics in the anisotropic Heisenberg model realized with ultracold atoms
Paul Niklas Jepsen, Wen Wei Ho, Jesse Amato-Grill +3
In Heisenberg models with exchange anisotropy, transverse spin components are not conserved and can decay not only by transport, but also by dephasing. Here we utilize ultracold at…
Spin transport in a tunable Heisenberg model realized with ultracold atoms
Niklas Jepsen, Jesse Amato-Grill, Ivana Dimitrova +3
Simple models of interacting spins play an important role in physics. They capture the properties of many magnetic materials, but also extend to other systems, such as bosons and f…
High-precision analysis of Feshbach resonances in a Mott insulator
Thomas Secker, Jesse Amato-Grill, Wolfgang Ketterle +1
We show that recent high-precision measurements of relative on-site interaction energies in a Mott insulator require a theoretical description beyond the standard Hubbard-mode…
Enhanced Superexchange in a Tilted Mott Insulator
Ivana Dimitrova, Niklas Jepsen, Anton Buyskikh +4
In an optical lattice entropy and mass transport by first-order tunneling is much faster than spin transport via superexchange. Here we show that adding a constant force (tilt) sup…
Interaction Spectroscopy of a Two-component Mott Insulator
Jesse Amato-Grill, Niklas Jepsen, Ivana Dimitrova +2
We prepare and study a two-component Mott insulator of bosonic atoms with two particles per site. The mapping of this system to a magnetic spin model, and the subsequent study of i…
