And if they don't dance, they are no friends of mine: Exploring boundaries of national identity
Nations and Nationalism, Volume 29, Issue 2, Page 579-597, April 2023., 2023 Abstract National identity is widely used to explain anti‐immigrant attitudes and thus the appeal for right‐wing (populist) parties. Yet, consensus on how to capture national identity is lacking. This article identifies ideal‐typical patterns of national boundary making across 42 countries and more than 25 years beyond the ethnic–civic dichotomy and ...

Feshbach spectroscopy and analysis of the interaction potentials of ultracold sodium [PDF]
, 2011 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

Multichannel effects in the Efimov regime from broad to narrow Feshbach resonances [PDF]
, 2020 We study Efimov physics of three identical bosons with pairwise multichannel interactions for Feshbach resonances of adjustable width. We find that the two-body multichannel nature of the interaction can affect the universal three-body spectrum ...

Characterizing the temperature dependence of Fano-Feshbach resonances of ultracold polarized thulium [PDF]
Physical Review A, 2020 Recent studies demonstrated anomalous temperature shifts for some Fano-Feshbach resonances of thulium atoms. These anomalies were explained by the variation in light intensity in the optical dipole trap, which accompanied changes in temperature.

A Quantum Model of Feshbach Resonances [PDF]
Annales Henri Poincaré, 2019 We consider a quantum model of two-channel scattering to describe the mechanism of a Feshbach resonance. We perform a rigorous analysis in order to count and localize the energy resonances in the perturbative regime, i.e., for small inter-channel coupling, and in the non-perturbative one.

Attractors of Modified Coupled Ginzburg–Landau Model
Mathematical Problems in Engineering, Volume 2023, Issue 1, 2023., 2023 Bose–Einstein condensation is a gaseous, superfluid state of matter exhibited by bosons as they cool to near absolute zero, which was discovered as early as 1924 but was not experimentally realized until 1995. In 2006, Machida and Koyama developed the corresponding Ginzburg–Landau model for superfluid and Bose–Einstein condensation‐spanning phenomena ...

Observation of Feshbach resonances between alkali and closed-shell atoms [PDF]
Nature Physics, 2017 Magnetic Feshbach resonances allow control of the interactions between ultracold atoms1. They are an invaluable tool in studies of few-body and many-body physics2,3, and can be used to convert pairs of atoms into molecules4,5 by ramping an applied ...

Nonlinear localized modes in one‐dimensional nanoscale dark‐state optical lattices
Nanophotonics, Volume 11, Issue 15, Page 3465-3474, August 2022., 2022 Abstract Optical lattices (OLs) with conventional spatial periodic λ/2, formed by interfering the counterpropagating laser beams with wavelength λ, are versatile tools to study the dynamical and static properties of ultracold atoms. OLs with subwavelength spatial structure have been realized in recent quantum‐gas experiment, offering new possibility ...

Random to Chaotic Statistic Transformation in Low-Field Fano-Feshbach Resonances of Cold Thulium Atoms. [PDF]
Physical Review Letters, 2019 Here, we report on the observation of a random to chaotic temperature transformation in the statistics of nearest-neighbor spacings of Fano-Feshbach resonances in the ultracold polarized gas of thulium-169 atoms.

HIGH TEMPERATURE SUPERFLUID AND FESHBACH RESONANCE [PDF]
International Journal of Modern Physics B, 2005 We study an effective field theory describing cold fermionic atoms near a Feshbach resonance. The effective theory gives a precise description of the dynamics in the limit that the energy of the Feshbach resonance is tuned to be twice that of the Fermi surface.
