Heteronuclear Molecules from a Quantum Degenerate FermiFermi Mixture: A MassImbalanced Fermi System,Used
Delivery time: 8-12 business days (International)
This thesis reports on experiments with quantum degenerate atomic mixtures and molecular gases at ultracold temperatures. The work describes the first realization of a quantum degenerate FermiFermi mixture of two different species with unequal masses. In addition, the first quantum degenerate threespecies mixture is realized. Furthermore, the first heteronuclear bosonic molecules with temperatures close to quantum degeneracy are created from a twospecies mixture. The heteronuclear Fermi mixture adds the mass ratio and the different internal structure as new parameters to quantum degenerate Fermi gases. The molecular cloud being close to quantum degeneracy marks the first starting point for the realization of a heteronuclear molecular BEC and to investigate the BECBCS crossover with unequal masses. Moreover, the molecules can be transferred into the rovibrational ground state to create a polar BEC with an anisotropic, longrange interaction.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
