Engineering diffraction: Control of broad-area lasers and shaping atomic interactions for quantum simulation

One intriguing consequence of diffractive dephasing are self-imaging phenomena as the Talbot effect. The talk will discuss several applications of that in the control of broad-area lasers and quantum simulation. The proposition of [1] to control the modal structure of broad-area edge-emitting semiconductor lasers via a two-dimensional gain-loss variation is interpreted via the Talbot effect. Coupling scheme for atomic states via an optical feedback loop with diffractive dephasing are discussed for supersolids [2], magnetic dipole structures implementing the Ising model and novel magnetic quadrupole states stored in quantum coherences.
