We extend a model of two-center interference to include the superposition of opposite orientations in aligned polar molecules. We show that the position of the minimum in the harmonic spectrum from bo...
Harmonics generation and intense terahertz radiation from polar molecules at multiphoton resonant excitation in laser fields

By selecting two dressed rotational states of ultracold polar molecules in an optical lattice, we obtain a highly tunable generalization of the t-J model, which we refer to as the t-J-V -W model. In a...
