Observation of brane parity order in programmable optical lattices
David Wei, Daniel Adler, Kritsana Srakaew +4
The Mott-insulating phase of the two-dimensional (2d) Bose-Hubbard model is expected to be characterized by a non-local brane parity order. Parity order captures the presence of mi…
Realizing distance-selective interactions in a Rydberg-dressed atom array
Simon Hollerith, Kritsana Srakaew, David Wei +10
Measurement-based quantum computing relies on the rapid creation of large-scale entanglement in a register of stable qubits. Atomic arrays are well suited to store quantum informat…
Quantum gas microscopy of Kardar-Parisi-Zhang superdiffusion
David Wei, Antonio Rubio-Abadal, Bingtian Ye +9
The Kardar-Parisi-Zhang (KPZ) universality class describes the coarse-grained behavior of a wealth of classical stochastic models. Surprisingly, it was recently conjectured to also…
Tracking evaporative cooling of a mesoscopic atomic quantum gas in real time
Johannes Zeiher, Julian Wolf, Joshua A. Isaacs +2
The fluctuations in thermodynamic and transport properties in many-body systems gain importance as the number of constituent particles is reduced. Ultracold atomic gases provide a…
Many-body delocalization in the presence of a quantum bath
Antonio Rubio-Abadal, Jae-yoon Choi, Johannes Zeiher +4
Closed generic quantum many-body systems may fail to thermalize under certain conditions even after long times, a phenomenon called many-body localization (MBL). Numerous studies s…
Exploring the many-body localization transition in two dimensions
Jae-yoon Choi, Sebastian Hild, Johannes Zeiher +7
One fundamental assumption in statistical physics is that generic closed quantum many-body systems thermalize under their own dynamics. Recently, the emergence of many-body localiz…
Many-body interferometry of a Rydberg-dressed spin lattice
Johannes Zeiher, Rick van Bijnen, Peter Schauß +5
Ultracold atoms are an ideal platform to study strongly correlated phases of matter in and out of equilibrium. Much of the experimental progress in this field crucially relies on t…
Spatially Resolved Detection of a Spin-Entanglement Wave in a Bose-Hubbard Chain
Takeshi Fukuhara, Sebastian Hild, Johannes Zeiher +4
Entanglement is an essential property of quantum many-body systems. However, its local detection is challenging and was so far limited to spin degrees of freedom in ion chains. Her…
Far-from-equilibrium spin transport in Heisenberg quantum magnets
Sebastian Hild, Takeshi Fukuhara, Peter Schauß +5
We study experimentally the far-from-equilibrium dynamics in ferromagnetic Heisenberg quantum magnets realized with ultracold atoms in an optical lattice. After controlled imprinti…
