Project-C1

Light control of spinor quantum gases

Juliette Simonet, Klaus Sengstock

Project C1 studies bosonic spinor quantum gases in externally driven optical lattices. The driving allows implementing a dynamical control of the tunneling as well as the geometry of the optical lattice. This system is well suited for the investigation of various spin models, which are essential for our understanding of magnetism and its non-equilibrium properties (together with C9). The second core aspect of the project is the realization of artificial graphene with bosonic quantum gases and the study of non-equilibrium dynamics of charge carriers and interband relaxation as well as ‘strongly correlated’ graphene (collaboration with B6, C2, C3, C6 and C9).  As a third objective, several driving schemes will be implemented in order to reproduce the effects of light on an electronic system and, thus, to control the properties of quantum matter (collaboration with B6, B7, C2 and C7).
