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…

Control and Entanglement of Individual Rydberg Atoms Near a Nanoscale Device

Paloma L. Ocola, Ivana Dimitrova, Brandon Grinkemeyer +5

Rydberg atom arrays constitute a promising quantum information platform, where control over several hundred qubits has been demonstrated. Further scaling could significantly benefi…

Catching Bethe phantoms and quantum many-body scars: Long-lived spin-helix states in Heisenberg magnets

Paul Niklas Jepsen, Yoo Kyung Lee, Hanzhen Lin +4

Exact solutions for quantum many-body systems are rare and provide valuable insight to universal phenomena. Here we show experimentally in anisotropic Heisenberg chains that specia…

Entanglement transport and a nanophotonic interface for atoms in optical tweezers

Tamara Đorđević, Polnop Samutpraphoot, Paloma L. Ocola +5

The realization of an efficient quantum optical interface for multi-qubit systems is an outstanding challenge in science and engineering. Using two atoms in individually-controlled…

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…

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…

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.…
