Direct observation of a Feshbach resonance by coincidence detection of ions and electrons in Penning ionization collisions [PDF]
Nature Communications, 2020 Here the authors use ion-electron coincidence imaging method to explore collision dynamics. They observe Feshbach resonance in the Penning ionization collision of argon and excited helium atoms, resulting in singly charged argon ion and ground state ...

Experimental realization of a Rydberg optical Feshbach resonance in a quantum many-body system [PDF]
Nature Communications, 2018 Ultracold Rydberg molecules have characteristic properties that can be exploited for quantum control and applications. Here the authors demonstrate a Rydberg optical Feshbach resonance, which is based on ultra-long-range Rydberg molecules.

Above-threshold scattering about a Feshbach resonance for ultracold atoms in an optical collider [PDF]
Nature Communications, 2017 Studies on energy-dependent scattering of ultracold atoms were previously carried out near zero collision energies. Here, the authors observe a magnetic Feshbach resonance in ultracold Rb collisions for above-threshold energies and their method can also ...

Quantum Thermalization Dynamics of Fermi Gases Quenched to the BEC-BCS Crossover. [PDF]
Adv Sci (Weinh)This study, reporting the first experimental realization of interaction quench far faster than the Fermi timescale in fermionic many‐body systems, explores real‐time quantum thermalization dynamics in the BEC‐BCS crossover. It observes prethermal states with distinct lifetimes after quantum quench, uncovers universal prethermal scaling, and observes ...

Feshbach hypothesis of high-Tc superconductivity in cuprates [PDF]
Nature CommunicationsResonant interactions associated with the emergence of a bound state constitute one of the cornerstones of modern many-body physics. Here we present a Feshbach perspective on the origin of strong pairing in Fermi-Hubbard type models.

The Role of Benzonitrile Chlorination Explored by Dissociative Electron Attachment. [PDF]
ChemphyschemExperimental and theoretical dissociative electron attachment study of 2‐ and 4‐chlorobenzonitrile. The dissociative electron attachment process to ortho‐ and para‐chlorobenzonitrile was investigated in the 0–12 eV energy range with a crossed‐beam time‐of‐flight mass spectrometer, supported by quantum chemical scattering calculations.

Reshaped three-body interactions and the observation of an Efimov state in the continuum [PDF]
Nature CommunicationsEfimov trimers are exotic three-body quantum states that emerge from the different types of three-body continua in the vicinity of two-atom Feshbach resonances. In particular, as the strength of the interaction is decreased to a critical point, an Efimov

Polaritonic quantum matter. [PDF]
NanophotonicsAbstract Polaritons are quantum mechanical superpositions of photon states with elementary excitations in molecules and solids. The light–matter admixture causes a characteristic frequency‐momentum dispersion shared by all polaritons irrespective of the microscopic nature of material excitations that could entail charge, spin, lattice or orbital ...

High phase-space density gas of NaCs Feshbach molecules
Physical Review Research, 2022 We report on the creation of ultracold gases of bosonic Feshbach molecules of NaCs. The molecules are associated from overlapping gases of Na and Cs using a Feshbach resonance at 864.12(5)G.
