    We demonstrate how photoassociation of fermions in optical lattices can create bosonic molecules. This process maps to a quantum optics model, enabling the construction of a molecular micromaser at each lattice site.

    Area of Science:

    • Quantum optics
    • Atomic physics
    • Condensed matter physics

    Background:

    • Fermions in optical lattices are a key system for studying quantum phenomena.
    • Photoassociation is a method to create molecules from atoms.
    • The Jaynes-Cummings model describes light-matter interactions in quantum optics.

    Purpose of the Study:

    • To investigate the photoassociation of fermions into bosonic molecules in a 2D optical lattice.
    • To establish a connection between this process and the Jaynes-Cummings Hamiltonian.
    • To propose a method for creating a molecular micromaser.

    Main Methods:

    • Mapping the photoassociation of two fermions into a generalized Jaynes-Cummings Hamiltonian.
    • Analyzing the quantum optical properties of the molecular field.
