Optical Lattices
Multiple Matter Wave Interference Pattern
from a 1D and 2D Optical Lattice Potential
Matter wave interference pattern from a (top Row) 1D vertical lattice, (middle row) 1D horizontal lattice and (bottom row) from a 2D horizontal+vertical optical lattice. Lattice potential depth increases from left to right.
Multiple Matter Wave Interference Pattern from a 2D Optical Lattice Showing s-Wave Scattering Spheres
After switching off an optical lattice with a high density of atoms, s-wave scattering spheres become visible (here eight are clearly visible) due to collisions of the atoms in the different separating momentum components.
Phase Grating for Atoms
By pulsing on a 2D optical lattice for a very short time, the condensate is projected onto several momentum components. Almost 80 of these momentum components can be seen on this image.
Multiple Matter Wave Interference (Simulation)
Simulation of the multiple matter wave interference pattern of a small lattice (5x5 lattice sites) after the lattice potential has been turned off.
