Pagina 24 - This matter wave field has a fixed phase relative to all other coherent matter wave fields on different lattice sites. If, on the other hand, interactions dominate the behavior of the Hamiltonian, such that U/J ^> 1, then fluctuations in the atom number on a single lattice site become energetically costly and the ground state of the system will instead consist of localized atomic wave functions that minimize the interaction energy. The manybody ground state is then a product of local Fock states...
Pagina 26 - In the superfluid regime [55], the phase coherence of the matter wave field across the lattice characterizes the many-body state. This can be observed by suddenly turning off all trapping fields, such that the individual matter wave fields on different lattice sites expand and interfere with each other. After a fixed time of flight period the atomic density distribution can then be measured by absorption imaging. Such an image directly reveals co - d.
Pagina 24 - ... energy. It is important to note that precisely the atom number fluctuations due to the delocalized single particle wave functions make the "superfluid" state unfavorable for large U. Such a change can be induced by adiabatically increasing the barrier height in the double well system, such that J decreases exponentially and the energy cost for populating the antisymmetric state becomes smaller and smaller. Eventually it will then be favorable for the system to change from the "superfluid...
Pagina 28 - Due to the onsite repulsion between the atoms, however, such an excitation costs energy U which is usually not available to the system. Therefore these are only allowed in virtual processes and an atom in general has to remain immobile at its original position. If one adds a potential gradient such that the energy difference between neighboring lattice sites AE exactly matches the onsite energy cost U, then such an excitation becomes energetically possible and one is able to resonantly perturb the...
