Ultracold field-linked tetratomic molecules
Xing-Yan Chen, Shrestha Biswas, Sebastian Eppelt +7
Ultracold polyatomic molecules offer intriguing new opportunities in cold chemistry, precision measurements, and quantum information processing, thanks to their rich internal struc…
Ultracold Sticky Collisions: Theoretical and Experimental Status
Roman Bause, Arthur Christianen, Andreas Schindewolf +2
Collisional complexes, which are formed as intermediate states in molecular collisions, are typically short-lived and decay within picoseconds. However, in ultracold collisions inv…
Field-linked resonances of polar molecules
Xing-Yan Chen, Andreas Schindewolf, Sebastian Eppelt +7
Scattering resonances are an essential tool for controlling interactions of ultracold atoms and molecules. However, conventional Feshbach scattering resonances, which have been ext…
Effective potential and superfluidity of microwave-dressed polar molecules
Fulin Deng, Xing-Yan Chen, Xin-Yu Luo +3
For microwave-dressed polar molecules, we analytically derive an intermolecular potential composed of an anisotropic van der Waals shielding core and a long-range dipolar interacti…
Long-lived fermionic Feshbach molecules with tunable -wave interactions
Marcel Duda, Xing-Yan Chen, Roman Bause +3
Ultracold fermionic Feshbach molecules are promising candidates for exploring quantum matter with strong -wave interactions, however, their lifetimes were measured to be short.…
Evaporation of microwave-shielded polar molecules to quantum degeneracy
Andreas Schindewolf, Roman Bause, Xing-Yan Chen +4
Ultracold polar molecules offer strong electric dipole moments and rich internal structure, which makes them ideal building blocks to explore exotic quantum matter, implement novel…
Transition from a polaronic condensate to a degenerate Fermi gas of heteronuclear molecules
Marcel Duda, Xing-Yan Chen, Andreas Schindewolf +5
The interplay of quantum statistics and interactions in atomic Bose--Fermi mixtures leads to a phase diagram markedly different from pure fermionic or bosonic systems. However, inv…
Suppression of Unitary Three-body Loss in a Degenerate Bose-Fermi Mixture
Xing-Yan Chen, Marcel Duda, Andreas Schindewolf +3
We study three-body loss in an ultracold mixture of a thermal Bose gas and a degenerate Fermi gas. We find that at unitarity, where the interspecies scattering length diverges, the…
Efficient conversion of closed-channel dominated Feshbach molecules of NaK to their absolute ground state
Roman Bause, Akira Kamijo, Xing-Yan Chen +4
We demonstrate the transfer of NaK molecules from a closed-channel dominated Feshbach-molecule state to the absolute ground state. The Feshbach molecules are initiall…
Collisions of ultracold molecules in bright and dark optical dipole traps
Roman Bause, Andreas Schindewolf, Renhao Tao +7
Understanding collisions between ultracold molecules is crucial for making stable molecular quantum gases and harnessing their rich internal degrees of freedom for quantum engineer…
Tune-out and magic wavelengths for ground-state NaK molecules
Roman Bause, Ming Li, Andreas Schindewolf +5
We demonstrate a versatile, rotational-state dependent trapping scheme for the ground and first excited rotational states of NaK molecules. Close to the rotational ma…
Extending rotational coherence of interacting polar molecules in a spin-decoupled magic trap
Frauke Seeßelberg, Xin-Yu Luo, Ming Li +4
Superpositions of rotational states in polar molecules induce strong, long-range dipolar interactions. Here we extend the rotational coherence by nearly one order of magnitude to 8…
Beating the classical precision limit with spin-1 Dicke state of more than 10000 atoms
Yi-Quan Zou, Ling-Na Wu, Qi Liu +5
Interferometry is a paradigm for most precision measurements. Using uncorrelated particles, the achievable precision for a two-mode (two-path) interferometer is bounded by the…
