SUMMARY:JOINT ENGINEERING  & SCIENCE SEMINAR SERIES
DESCRIPTION:Quasi-One-Dimensional Quantum Gases: Effective Interactions\, Energetics and Correlations \nSince the first experimental realization of gaseous atomic Bose-Einstein condensates in 1995\, the field of cold atom physics has progressed and matured tremendously. \nNowadays\, the interaction strength of cold atom systems can be tuned essentially at will and the confinement geometry can be adjusted. This talk will summarize our theoretical studies of qusi-one-dimensional harmonically trapped atomic gases. A model Hamiltonian with effective one-dimensional atom-atom interactions will be introduced and its validity will be benchmarked. The excitation spectrum and two-body correlations of small two-component Fermi gases will be analyzed as a function of the interspecies interaction strength. The changes of the structural expectation values reveal an intriguing interplay between the interspecies interactions and the Pauli exclusion principle\, which can be thought of as corresponding to an effective intraspecies repulsion. Implications of our theoretical studies for cold atom experiments will bediscussed. \nPresented by \nDr. Doerte Blume\nMeyer Distinguished Professor of the College of Arts & Sciences\nDepartment of Physics and Astronomy\nWashington State University\ndoerte@wsu.edu \nProfessor Doerte Blume\, a theoretical physicist\, is interested in the\nmicroscopic behavior of few-particle systems\, especially in atomic\,\nmolecular and chemical physics.
