Spin Dependent Transport
Controlled interactions with spin dependent lattice potentials
Controlled interactions between atoms on different lattice sites can be realized with the help of spin-dependent lattice potentials. In such spin dependent potentials, atoms in a, let us say, blue internal state experience a different lattice potential than atoms in a red internal state. These lattices can be moved relative to each other such that two initially separated atoms can be brought into controlled contact with each other.
Delocalizing an atom by hand
With the help of a series of π/2- and π microwave pulses together an electro-optical modulator (EOM) it is possible to delocalize an atom in a completely controlled way over an arbitrary number of lattice site.
Matter wave interference patterns of atoms that have been coherently split over different lattice sites
By releasing the coherently split atom from the lattice trapping potential one can observe a double slit intereference pattern. This period of such an interference pattern becomes shortert the further the two wavepackets ahve been separated
