Phase protection of Fano-Feshbach resonances [PDF]
Nature Communications, 2020 The lifetime of decaying quantum states has been thought to depend on the strength of the coupling causing the decay. Here the authors demonstrate that quantum mechanical interference can dominate this process, observing Fano-Feshbach resonance lifetimes

High Temperature Superfluid and Feshbach Resonance [PDF]
International Journal of Modern Physics B, 2003 We study an effective field theory describing cold fermionic atoms near a Feshbach resonance. The theory gives a unique description of the dynamics in the limit that the energy of the Feshbach resonance is tuned to be twice that of the Fermi surface.

Tomography of Feshbach resonance states [PDF]
Science, 2023 Feshbach resonances are fundamental to interparticle interactions and become particularly important in cold collisions with atoms, ions, and molecules. In this work, we present the detection of Feshbach resonances in a benchmark system for strongly interacting and highly anisotropic collisions: molecular hydrogen ions colliding with noble gas atoms ...

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 ...

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 ...

Photonic Feshbach resonance [PDF]
Science China Physics, Mechanics and Astronomy, 2010 Hermann Feshbach predicted fifty years ago that when two atomic nuclei are scattered within an open entrance channel-- the state observable at infinity, they may enter an intermediate closed channel -- the locally bounded state of the nuclei. If the energy of a bound state of in the closed channel is fine-tuned to match the relative kinetic energy ...

Feshbach resonances in ultracold gases [PDF]
Reviews of Modern Physics, 2010 Feshbach resonances are the essential tool to control the interaction between atoms in ultracold quantum gases. They have found numerous experimental applications, opening up the way to important breakthroughs. This Review broadly covers the phenomenon of Feshbach resonances in ultracold gases and their main applications.

Polaritonic Cross Feshbach Resonance [PDF]
Physical Review Letters, 2019 We demonstrate the existence of a cross Feshbach resonance by strongly driving a lower polariton mode and by monitoring in time the transmission of a short optical pulse at the energy of the upper polariton mode in a semiconductor microcavity. From the signatures of the optical resonance, strength, and sign of the energy shift, we attribute the origin ...
