Polaronic hybridization of atoms, dimers and trimers in a Bose-Einstein condensate
Carsten Robens, Arthur Christianen, Alexander Y. Chuang +4
The Bose polaron problem of an impurity immersed in a Bose-Einstein condensate (BEC) has been predicted to feature strong correlations arising from bound states of multiple bosons…
Riemann Rarefaction Waves in a Strongly Interacting Fermi Gas
Eric A. Wolf, Martin Zwierlein
We investigate the expansion of a homogeneous, strongly interacting Fermi gas released into vacuum in a ``shock tube'' geometry. At unitarity, where the gas is scale invariant and…
Revealing Hidden Correlations in a Fermi-Hubbard system via Interaction Ramps
Botond Oreg, Carter Turnbaugh, Jens Hertkorn +2
We observe an enhanced visibility of charge-density-wave correlations in a cold-atom realization of the attractive Hubbard model following a rapid boost of the interaction strength…
Competition of fermion pairing, magnetism, and charge order in the spin-doped attractive Hubbard gas
Thomas Hartke, Botond Oreg, Chunhan Feng +7
The tension between fermion pairing and magnetism affects numerous strongly correlated electron systems, from high-temperature cuprates to twisted bilayer graphene. Exotic forms of…
In search of exotic pairing in the Hubbard model: many-body computation and quantum gas microscopy
Chunhan Feng, Thomas Hartke, Yuan-Yao He +5
Pair density waves and exotic superconductivity have long been of strong interest, and have attracted much recent attention. We present a joint theoretical and experimental explora…
Dual Spectroscopy of Quantum Simulated Fermi-Hubbard Systems
K. Knakkergaard Nielsen, M. Zwierlein, G. M. Bruun
Quantum gas microscopy with atoms in optical lattices provides remarkable insights into the real space properties of many-body systems, but does not directly reveal the nature of t…
