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 ...

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.

Superfluid transition temperature in a trapped gas of Fermi atoms with a Feshbach resonance

, 2002
We investigate strong coupling effects on the superfluid phase transition in a gas of Fermi atoms with a Feshbach resonance. The Feshbach resonance describes a composite quasi-Boson, which can give rise to an additional pairing interaction between the ...

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 ...

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/

Controlling phase separation of binary Bose-Einstein condensates via mixed-spin-channel Feshbach resonance

, 2010
We investigate controlled phase separation of a binary Bose-Einstein condensate (BEC) in the proximity of mixed-spin-channel Feshbach resonance in the |F = 1, mF = +1> and |F = 2,mF = -1> states of 87Rb at a magnetic field of 9.10 G.

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.

Ultracold Three-Body Collisions near Overlapping Feshbach Resonances [PDF]

Physical Review Letters, 2009
We present a comprehensive collection of ultracold three-body collisions properties near overlapping Feshbach resonances. Our results incorporate variations of all scattering lengths and demonstrate novel collisional behavior, such as atom-molecule interference effects.
