Imaging interatomic electron current in crystals with ultrafast resonant x-ray scattering
Daria Popova-Gorelova, Robin Santra
We demonstrate how the technique of ultrafast resonant x-ray scattering can be applied to imaging dynamics of electronic wave packets in crystals. We study scattering patterns from…
Optimal control of complex atomic quantum systems
S. van Frank, M. Bonneau, J. Schmiedmayer +8
Quantum technologies will ultimately require manipulating many-body quantum systems with high precision. Cold atom experiments represent a stepping stone in that direction: a high…
Impact of Many-Body Correlations on the Dynamics of an Ion-Controlled Bosonic Josephson Junction
J. M. Schurer, R. Gerritsma, P. Schmelcher +1
We investigate an atomic ensemble of interacting bosons trapped in a symmetric double well potential in contact with a single tightly trapped ion which has been recently proposed […
Exposing local symmetries in distorted driven lattices via time-averaged invariants
Thomas Wulf, Christian V. Morfonios, Fotis K. Diakonos +1
Time-averaged two-point currents are derived and shown to be spatially invariant within domains of local translation or inversion symmetry for arbitrary time-periodic quantum syste…
Probing superfluidity of Bose-Einstein condensates via laser stirring
Vijay Pal Singh, Wolf Weimer, Kai Morgener +5
We investigate the superfluid behavior of a Bose-Einstein condensate of Li molecules. In the experiment by Weimer et al., Phys. Rev. Lett. 114, 095301 (2015) a condensate is st…
Modulational instability and localized breather modes in the discrete nonlinear Schrödinger equation with helicoidal hopping
J. Stockhofe, P. Schmelcher
We study a one-dimensional discrete nonlinear Schrödinger model with hopping to the first and a selected N-th neighbor, motivated by a helicoidal arrangement of lattice sites. We p…
