Magnetic Feshbach resonances in collisions of 23Na40K with 40K

New Journal of Physics, 2021
We present measurements of more than 80 magnetic Feshbach resonances in collisions of ultracold ^23 Na ^40 K with ^40 K. We assign quantum numbers to a group of low-field resonances and show that they are probably due to long-range states of the ...

Molecular scale nanophotonics: hot carriers, strong coupling, and electrically driven plasmonic processes

Nanophotonics, Volume 13, Issue 13, Page 2281-2322, May 2024.
Abstract Plasmonic modes confined to metallic nanostructures at the atomic and molecular scale push the boundaries of light–matter interactions. Within these extreme plasmonic structures of ultrathin nanogaps, coupled nanoparticles, and tunnelling junctions, new physical phenomena arise when plasmon resonances couple to electronic, exitonic, or ...

Fermi-Bose mixture across a Feshbach resonance

, 2007
We study a dilute mixture of degenerate bosons and fermions across a Feshbach resonance of the Fermi-Fermi scattering length aF. This scattering length is renormalized by the boson-induced interaction between fermions and its value is crucial to ...

Creating a Bose-Einstein condensate of stable molecules using photoassociation and Feshbach resonance [PDF]

, 2014
Quantum degenerate molecular gases are of interest for the unique level of control they offer over chemical interactions and processes. To reach the quantum degenerate regime, these molecular gases must be cooled to ultracold temperatures, typically on ...

Collisional cooling of a Fermi gas with three-body recombination

Communications Physics
Evaporative cooling stands as the prevailing method for achieving ultracold temperatures in atomic systems. Current schemes of evaporation selectively remove the hotter atoms near the edge of the trap, as the hotter and colder atoms are distributed in ...

Observation of collectivity enhanced magnetoassociation of 6Li in the quantum degenerate regime

New Journal of Physics, 2022
The association process of Feshbach molecules is well described by a Landau–Zener (LZ) transition above the Fermi temperature, such that two-body physics dominates the dynamics.

Quantum defect theory description of weakly bound levels and Feshbach resonances in LiRb

New Journal of Physics, 2015
The multichannel quantum defect theory (MQDT) in combination with the frame transformation (FT) approach is applied to model the Fano–Feshbach resonances measured for ^7 Li ^87 Rb and ^6 Li ^87 Rb Marzok et al (2009 Phys. Rev. A http://dx.doi.org/10.1103/

Resonances in Systems Involving Positrons

Atoms, 2020
When an incident particle on a target gets attached to the target, the cross-section at that energy could be much larger compared to those at other energies. This is a short-lived state and decays by emitting an electron.
