Bifurcations in the non-dissipative dynamics of ultra cold atomsBen Upcroft, W. K. Hensinger, N.P. Heckenberg, G T Milburn, H. Rubinsztin-Dunlop, C. A. HolmesTechnical Digest. CLEO/Pacific Rim 2001. 4th…2001We present the first experimental observation of several bifurcations in a controllable non-linear Hamiltonian system. Dynamics of cold atoms are used to test predictions of non-linear, non-dissipative Hamiltonian dynamics.
