Feshbach spectroscopy of Cs atom pairs in optical tweezers

New Journal of Physics, 2022
We prepare pairs of ^133 Cs atoms in a single optical tweezer and perform Feshbach spectroscopy for collisions of atoms in the states ( f = 3, m _f = ±3).

We Feel, We Understand: Examining the Moderating Effects of Publics' Empathy on Crisis Outcomes Across Crisis Types and Response Strategies

Journal of Contingencies and Crisis Management, Volume 33, Issue 1, March 2025.
ABSTRACT This study examines how empathy, operationalized into affective and cognitive dimensions, influences stakeholders' perceptions during organisational crises. Also, the study explores the mediating role of account acceptance in the relationship between crisis response strategies and organisational outcomes.

The sources of national pride: Evidence from China and the United States

Nations and Nationalism, Volume 30, Issue 4, Page 547-564, October 2024.
Abstract National pride relates to nationalism, one of the most powerful forces in modern politics. Many surveys have shown that most citizens are proud of their countries, but few have directly examined the underlying reasons for why people are proud of their countries. Using parallel national surveys in China and the United States, we investigate the

Above-threshold scattering about a Feshbach resonance for ultracold atoms in an optical collider

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 ...

Vibrational Relaxation of D2O Induced by Collision with He: A Rigid Bender Close Coupling Study

ChemPhysChem, Volume 25, Issue 15, August 1, 2024.
The vibrational quenching cross sections for the relaxation of the D2O (ν2=1,3ka,kc) molecule by collision with He are presented. A monotonic increase of the cross sections is observed for high collision energies. Abstract The vibrational relaxation of the first excited bending state of D2O induced by collision with He is studied at the close coupling ...

Observation of bound state self-interaction in a nano-eV atom collider

Nature Communications, 2018
Self-interaction of a bound state through its coupling to the continuum is a phenomenon that is very difficult to observe. Here, the authors optically collide atomic clouds of rubidium and potassium to observe the self-interaction energy through precise ...

Low‐lying Negative Ion States Probed in Potassium – Ethanol Collisions

ChemPhysChem, Volume 25, Issue 14, July 15, 2024.
A joint experimental and theoretical investigation on ethanol negative ion formation by charge transfer is reported for the first time. The electronic state spectroscopy of the lowest‐lying anionic states is comprehensively discussed rendering special relevance to the role of the different shape and core‐excited Feshbach resonances, while the ...

Magnetic Feshbach resonances between atoms in ^{2}S and ^{3}P_{0} states: Mechanisms and dependence on atomic properties

Physical Review Research, 2023
Magnetically tunable Feshbach resonances exist in ultracold collisions between atoms in ^{2}S and ^{3}P_{0} states, such as an alkali-metal atom colliding with Yb or Sr in a clock state.

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 ...
