Lifetime of angular momentum in a rotating strongly interacting Fermi gas
S. Riedl, E. R. Sanchez Guajardo, C. Kohstall +2
We investigate the lifetime of angular momentum in an ultracold strongly interacting Fermi gas, confined in a trap with controllable ellipticity. To determine the angular momentum…
Collective oscillations of a Fermi gas in the unitarity limit: Temperature effects and the role of pair correlations
S. Riedl, E. R. Sanchez Guajardo, C. Kohstall +6
We present detailed measurements of the frequency and damping of three different collective modes in an ultracold trapped Fermi gas of Li atoms with resonantly tuned interactio…
Finite-Temperature Collective Dynamics of a Fermi Gas in the BEC-BCS Crossover
M. J. Wright, S. Riedl, A. Altmeyer +4
We report on experimental studies on the collective behavior of a strongly interacting Fermi gas with tunable interactions and variable temperature. A scissors mode excitation in a…
Order of Degrees of Freedom in Underdoped Manganites
E. R. Sanchez Guajardo
Using the degenerate double exchange Hamiltonian with on-site Coulomb interactions we show how the spin, charge, and orbital state degrees of freedom vary in La_{1-x}Ca_{x}MnO_{3}…
Quantum Ferroelectric Magnets in Underdoped Manganites
E. R. Sanchez Guajardo
Using the degenerate double exchange Hamiltonian with on-site Coulomb interactions we show that there is an instability towards the displacement of the manganese ion in La_{1-x}Ca_…
