We present the first detailed computations of wave optics effects in the gravitational lensing of binary systems. The field is conceptually rich, combining the caustic singularities produced in classical gravitational lensing with quantum (wave) interference effects. New techniques have enabled us to overcome previous barriers to computation. Recent developments in radio astronomy present observational opportunities which, while still futuristic, appear promising.

    math-ph 2026-06 unverdicted novelty 7.0 of 10

    A geometric South-East rule combined with Borel-plane values and resurgence adjacency identifies contributing critical points for asymptotics of integrals e^{i k f(x)} over R^d without Picard-Lefschetz flows.

  3. Which Saddles Contribute? The South-East Rule for Multidimensional Integrals

    math-ph 2026-06 conditional novelty 7.0 of 10

    A proposed "South-East rule" reads the directions of edges in a Borel-plane adjacency graph of critical values to decide, without steepest-descent flow computations, which complex and real saddles contribute to multid...
