    "abstract": "It is shown that the two-step excitation scheme typically used to create an\nultracold Rydberg gas can be described with an effective two-level rate\nequation, greatly reducing the complexity of the optical Bloch equations. This\nallows us to solve the many-body problem of interacting cold atoms with a Monte\nCarlo technique. Our results reproduce the Rydberg blockade effect. However, we\ndemonstrate that an Autler-Townes double peak structure in the two-step\nexcitation scheme, which occurs for moderate pulse lengths as used in the\nexperiment, can give rise to an antiblockade effect. It is observable in a\nlattice gas with regularly spaced atoms. Since the antiblockade effect is\nrobust against a large number of lattice defects it should be experimentally\nrealizable with an optical lattice created by CO$_{2}$ lasers.",
