We investigate anomalous damping of the monopole mode of a non-degenerate 3D Bose gas under isotropic harmonic confinement as recently reported by the JILA TOP trap experiment (Lobser et al in preparation). Given a realistic confining potential. we develop a model for studying collective modes that includes the effects of anharmonic corrections to a harmonic potential. By studying the... https://jalyttlers.shop/product-category/dominos/
