Velocity-dependent quantum phase slips in 1D atomic superfluids [PDF]
, 2016 Quantum phase slips are the primary excitations in one-dimensional superfluids and superconductors at low temperatures but their existence in ultracold quantum gases has not been demonstrated yet.

Transport, atom blockade and output coupling in a Tonks-Girardeau gas [PDF]
, 2011 Recent experiments have demonstrated how quantum-mechanical impurities can be created within strongly correlated quantum gases and used to probe the coherence properties of these systems [S. Palzer, C. Zipkes, C. Sias, and M. K\"ohl, Phys. Rev. Lett. 103,

Finite-size effects on the cluster expansions for quantum gases in restricted geometries
, 2022 We have analytically obtained 1-particle density matrices for ideal Bose and Fermi gases in both the 3-D box geometries and the harmonically trapped geometries for the entire range of temperature.

Probing nonlocal spatial correlations in quantum gases with ultra-long-range Rydberg molecules [PDF]
Physical Review A, 2019 We present photo-excitation of ultra-long-range Rydberg molecules as a probe of spatial correlations in quantum gases. Rydberg molecules can be created with well-defined internuclear spacing, set by the radius of the outer lobe of the Rydberg electron ...

Colloquium: Atomic quantum gases in periodically driven optical lattices [PDF]
, 2016 Dynamics of quantum many-body systems is one of the most complex problems in physics since it involves the time evolution of a large number of particles that interact with each other under the influence of external forces. With ultracold atoms in optical

Modulation-assisted tunneling in laser-fabricated photonic Wannier–Stark ladders
New Journal of Physics, 2015 We observe Wannier–Stark (W–S) localization in curved photonic lattices, realized using arrays of evanescently coupled optical waveguides. By correctly tuning the strength of inter-site coupling in the lattice, we observe that W–S states become ...

Probing Quantum Speed Limits with Ultracold Gases. [PDF]
Physical Review Letters, 2020 Quantum speed limits (QSLs) rule the minimum time for a quantum state to evolve into a distinguishable state in an arbitrary physical process. These fundamental results constrain a notion of distance traveled by the quantum state, known as the Bures ...

New Journal of Physics, 2012 Strongly correlated quantum fluids are phases of matter that are intrinsically quantum mechanical and that do not have a simple description in terms of weakly interacting quasiparticles.

Methods for preparing quantum gases of lithium. [PDF]
Review of Scientific Instruments, 2019 Lithium is an important element in atomic quantum gas experiments because its interactions are highly tunable due to broad Feshbach resonances and zero-crossings and because it has two stable isotopes: 6Li, a fermion, and 7Li, a boson.

Dynamics of ultracold quantum gases in the dissipative Fermi–Hubbard model [PDF]
Quantum Science and Technology, 2018 We employ metastable ultracold 173Yb atoms to study dynamics in the 1D dissipative Fermi–Hubbard model experimentally and theoretically, and observe a complete inhibition of two-body losses after initial fast transient dynamics.
