Observing the emergence of a quantum phase transition -- shell by shell
Luca Bayha, Marvin Holten, Ralf Klemt +6
Many-body physics describes phenomena which cannot be understood looking at a systems' constituents alone. Striking manifestations are broken symmetry, phase transitions, and colle…
Measurement of Identical Particle Entanglement and the Influence of Antisymmetrisation
Jan Hendrik Becher, Enrico Sindici, Ralf Klemt +3
We explore the relationship between symmetrisation and entanglement through measurements on few-particle systems in a multi-well potential. In particular, considering two or three…
Density Oscillations Induced by Individual Ultracold Two-Body Collisions
Q. Guan, V. Klinkhamer, R. Klemt +5
Access to single-particle momenta provides new means of studying the dynamics of a few interacting particles. In a joint theoretical and experimental effort, we observe and analyze…
High-Contrast Interference of Ultracold Fermions
Philipp M. Preiss, Jan Hendrik Becher, Ralf Klemt +4
Many-body interference between indistinguishable particles can give rise to strong correlations rooted in quantum statistics. We study such Hanbury Brown-Twiss-type correlations fo…
Experimental Characterization of Two-Particle Entanglement through Position and Momentum Correlations
Andrea Bergschneider, Vincent M. Klinkhamer, Jan Hendrik Becher +5
Quantum simulation is a rapidly advancing tool to gain insight into complex quantum states and their dynamics. Trapped ion systems have pioneered deterministic state preparation an…
Spin-resolved single-atom imaging of Li in free space
Andrea Bergschneider, Vincent M. Klinkhamer, Jan Hendrik Becher +4
We present a versatile imaging scheme for fermionic Li atoms with single-particle sensitivity. Our method works for freely propagating particles and completely eliminates the n…
High temperature pairing in a strongly interacting two-dimensional Fermi gas
Puneet A. Murthy, Mathias Neidig, Ralf Klemt +7
We observe many-body pairing in a two-dimensional gas of ultracold fermionic atoms at temperatures far above the critical temperature for superfluidity. For this, we use spatially…
