TITLE: Ultracold bosonic and fermionic atoms in an optical lattice
Abstract
A standing wave of a laser beam provides artificial crystal structure, which is called optical lattice. The optical lattice is fully controllable and it offers tunability and dynamical control to experimental system. Systems of ultracold atoms loaded in an optical lattice provide experimental means to realize matter-wave interferometers as well as to model many condensed matter systems, especially Hubbard system. In Bose-Hubbard model, there are two quantum phases: superfluid(SF), Mott insulator(MI). After the quantum phase transition between SF and MI phases using Bose Einstein condensates (BEC) in an optical lattice was demonstrated in 2002, many studies has been followed to understand the MI phase of this system, an important paradigm for the suppression of transport by particle correlation. In this talk, I am going to briefly report three experiments done using BEC in optical lattice; atom parametric amplification in optical lattice, shell structures of the MI phase, and transport proerties of the SF and MI phase. Then, the experiment with fermionic atoms in an optical lattice is covered.
