Using superlattice potentials to probe long-range magnetic correlations in optical lattices
Kim G. L. Pedersen, Brian M. Andersen, Georg M. Bruun +1
In Pedersen et al. (2011) we proposed a method to utilize a temporally dependent superlattice potential to mediate spin-selective transport, and thereby probe long and short range…
Signatures of the superfluid to Mott insulator transition in equilibrium and in dynamical ramps
D. Pekker, B. Wunsch, T. Kitagawa +3
We investigate the equilibrium and dynamical properties of the Bose-Hubbard model and the related particle-hole symmetric spin-1 model in the vicinity of the superfluid to Mott ins…
Inducing spin-dependent tunneling to probe magnetic correlations in optical lattices
K. G. L. Pedersen, B. M. Andersen, O. F. Syljuasen +2
We suggest a simple experimental method for probing antiferromagnetic spin correlations of two-component Fermi gases in optical lattices. The method relies on a spin selective Rama…
Measuring spin correlations in optical lattices using superlattice potentials
K. G. L. Pedersen, B. M. Andersen, G. M. Bruun +2
We suggest two experimental methods for probing both short- and long-range spin correlations of atoms in optical lattices using superlattice potentials. The first method involves a…
Antiferromagnetic noise correlations in optical lattices
G. M. Bruun, O. F. Syljuasen, K. G. L. Pedersen +3
We analyze how noise correlations probed by time-of-flight (TOF) experiments reveal antiferromagnetic (AF) correlations of fermionic atoms in two-dimensional (2D) and three-dimensi…
Adiabatic preparation of many-body states in optical lattices
Anders S. Sorensen, Ehud Altman, Michael Gullans +3
We analyze a technique for the preparation of low entropy many body states of atoms in optical lattices based on adiabatic passage. In particular, we show that this method allows p…
