Journal ArticleDOI
Gauge fields in the separation of rotations and internal motions in the n-body problem
TL;DR: In this article, the authors present a review on the case of nonrelativistic, n-body systems not subject to external torques, and develop the gauge theory of rotations and internal motions in detail.
Journal ArticleDOI
Dark solitons in atomic Bose-Einstein condensates: from theory to experiments
TL;DR: In this article, an overview of the theoretical and experimental progress on the study of matter-wave dark solitons in atomic Bose-Einstein condensates is presented.
Book ChapterDOI
Linear redshift distortions: A Review
TL;DR: In this article, the authors reviewed the measurements of β from linear redshift distortions published up to mid 1997 and reported the average and standard deviation of the reported values is β optical= 052 ± 026 for optically selected galaxies, and β IRAS = 077 + 022 for IRAS selected galaxies.
Journal ArticleDOI
Schrieffer-Wolff transformation for quantum many-body systems
TL;DR: The Schrieffer-Wolff (SW) method as mentioned in this paper is a version of degenerate perturbation theory in which the low-energy effective Hamiltonian H is obtained from the exact Hamiltonian by a unitary transformation decoupling the low energy and high-energy subspaces.
Journal ArticleDOI
Determination of Centrifugal Distortion Coefficients of Asymmetric‐Top Molecules. III. Sextic Coefficients
TL;DR: The rotational Hamiltonian of an asymmetric top molecule, containing terms up to sixth degree in the components of the total angular momentum, is transformed by a unitary transformation to a reduced Hamiltonian, so as to avoid the indeterminacies inherent in fitting the complete Hamiltonian to observed energy levels as discussed by the authors.
