Extracting the field theory description of a quantum many-body system from experimental data
Torsten V. Zache, Thomas Schweigler, Sebastian Erne +2
Quantum field theory is a powerful tool to describe the relevant physics governing complex quantum many-body systems. Here we develop a general pathway to extract the irreducible b…

Designing Arbitrary One-dimensional Potentials on an Atom Chip
Mohammadamin Tajik, Bernhard Rauer, Thomas Schweigler +6
We use laser light shaped by a digital micro-mirror device to realize arbitrary optical dipole potentials for one-dimensional (1D) degenerate Bose gases of 87Rb trapped on an atom…

Correlations and dynamics of tunnel-coupled one-dimensional Bose gases
Thomas Schweigler
We present a series of experiments performed with two ultracold one-dimensional Bose gases (rubidium atoms) in a double well potential. Employing matter-wave interference, we can m…
