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

Feshbach resonance-induced Fano interference in photoassociation [PDF]
We consider photoassociation from a state of two free atoms when the continuum state is close to a magnetic field induced Feshbach resonance and analyze Fano interference in photoassociation. We show that the minimum in photoassociation profiles characterized by the Fano asymmetry parameter $q$ is independent of laser intensity, while the maximum ...

Feshbach spectroscopy and analysis of the interaction potentials of ultracold sodium [PDF]
We have studied magnetic Feshbach resonances in an ultracold sample of Na prepared in the absolute hyperfine ground state. We report on the observation of three s-, eight d-, and three g-wave Feshbach resonances, including a more precise determination of

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

p-Wave Optical Feshbach Resonances in Yb-171
We study the use of an optical Feshbach resonance to modify the p-wave interaction between ultracold polarized Yb-171 spin-1/2 fermions. A laser exciting two colliding atoms to the 1S_0 + 3P_1 channel can be detuned near a purely-long-range excited ...

Feshbach Resonance in Dense Ultracold Fermi Gases [PDF]
We propose a coherent framework allowing to deal with many-body effects in dense ultracold Fermi gases in the presence of a Feshbach resonance. We show that the simple effect of Pauli exclusion induces a strong modification of the basic scattering properties, leading in particular to an energy dependence of the effective scattering length on the scale ...

Low‐lying Negative Ion States Probed in Potassium – Ethanol Collisions
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 in collisions of 23Na40K with 40K
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 ...

Dressed Feshbach molecules in the BEC-BCS crossover
We present the RPA theory of the BEC-BCS crossover in an atomic Fermi gas near a Feshbach resonance that includes the relevant two-body atomic physics exactly. This allows us to determine the probability $Z$ for the dressed molecules in the Bose-Einstein
