The scope of analog simulation in atomic, molecular, and optical systems has expanded
greatly over the past decades. Recently, the idea of synthetic dimensions—in which …

Geometric frustration of particle motion in a kagome lattice causes the single-particle band
structure to have a flat s-orbital band. We probe this band structure by placing a Bose …

We study the influence of atomic interactions on quantum simulations in momentum-space
lattices (MSLs), where driven transitions between discrete momentum states mimic transport …

Ramsey interferometers using internal electronic or nuclear states find wide applications in
science and engineering. We develop a matter wave Ramsey interferometer for trapped …

Theoretical studies of coherent atom transport have as yet mainly been restricted to one-
dimensional model systems with harmonic trapping potentials. Here we investigate this …

We demonstrate that the interplay between a nonlinearity and PT symmetry in a periodic
potential results in peculiar features of nonlinear periodic solutions. These include …

We experimentally engineer a moatlike dispersion in a system of weakly interacting bosons.
By periodically modulating the amplitude of a checkerboard optical lattice, the two lowest …

Typically, energy levels change without bifurcating in response to a change of a control
parameter. Bifurcations can lead to loops or swallowtails in the energy spectrum. The …

Single-particle dynamics of a spin-orbit-coupled Bose-Einstein condensate has recently
been investigated in experiments that explore the physics of Landau-Zener tunneling and of …
