Ultracold Feshbach molecules in an orbital optical lattice
Yann Kiefer, Max Hachmann, Andreas Hemmerich
Quantum gas systems provide a unique experimental platform to study a fundamental paradigm of quantum many-body physics: the crossover between Bose-Einstein condensed (BEC) molecul…
Predicting the transverse emittance of space charge dominated beams using the phase advance scan technique and a fully connected neural network
F. Mayet, M. Hachmann, K. Floettmann +5
The transverse emittance of a charged particle beam is an important figure of merit for many accelerator applications, such as ultra-fast electron diffraction, free electron lasers…
Quantum degenerate Fermi gas in an orbital optical lattice
M. Hachmann, Y. Kiefer, J. Riebesehl +2
Spin-polarized samples and spin mixtures of quantum degenerate fermionic atoms are prepared in selected excited Bloch bands of an optical chequerboard square lattice. For the spin-…
Metastable order protected by destructive many-body interference
M. Nuske, J. Vargas, M. Hachmann +3
The phenomenon of metastability can shape dynamical processes on all temporal and spatial scales. Here, we induce metastable dynamics by pumping ultracold bosonic atoms from the lo…
