2PP Papers

A technical breakdown of a controversial 2021 paper that uses worldline numerics on custom Casimir cavities to argue for a nanoscale energy distribution qualitatively similar to the Alcubierre warp metric, focusing on the 2PP-fabricated test geometry, the vacuum-energy modeling, and what this does and does not imply experimentally.

A technical breakdown of the first on-sky demonstration of a PIAACMC coronagraph with MagAO-X, focusing on the printed focal-plane masks, achieved inner working angle, contrast limits, and what this means for direct imaging of temperate exoplanets.

DOI: https://doi.org/10.48550/arXiv.2602.23016

A technical breakdown of a bioinspired pumpless microneedle that mimics Ligia exotica leg microstructures to transport fluid without external pumping, focusing on microstructure layout, capillary transport, and device characterization.
