Ultracold quantum gases in triangular optical lattices
C. Becker, P. Soltan-Panahi, J. Kronjäger +3
Over the last years the exciting developments in the field of ultracold atoms confined in optical lattices have led to numerous theoretical proposals devoted to the quantum simulat…
Momentum-Resolved Bragg Spectroscopy in Optical Lattices
P. T. Ernst, S. Götze, J. S. Krauser +4
Strongly correlated many-body systems show various exciting phenomena in condensed matter physics such as high-temperature superconductivity and colossal magnetoresistance. Recentl…
Frustrated quantum antiferromagnetism with ultracold bosons in a triangular lattice
Andre Eckardt, Philipp Hauke, Parvis Soltan-Panahi +3
We propose to realize the anisotropic triangular-lattice Bose-Hubbard model with positive tunneling matrix elements by using ultracold atoms in an optical lattice dressed by a fast…
Spontaneous pattern formation in an anti-ferromagnetic quantum gas
Jochen Kronjäger, Christoph Becker, Parvis Soltan-Panahi +2
Spontaneous pattern formation is a phenomenon ubiquitous in nature, examples ranging from Rayleigh-Benard convection to the emergence of complex organisms from a single cell. In ph…
