An Undecidability Proof for the Plan Existence Problem

Antonis Achilleos · 2026

The plan existence problem asks, given a goal in the form of a formula in modal logic, an initial epistemic state (a pointed Kripke model), and a set of epistemic actions, whether there exists a seque…

Thin Film AlN Microbolometer for Very Long-Wave Infrared Detection

Vivek Tallavajhula, Zarko Sakotic, Ian Anderson, Yinan Wang, Daniel Wasserman, Ruochen Lu · 2026

We demonstrate a suspended thin-film aluminum nitride (AlN) microbolometer for narrowband very long-wave infrared detection. The device uses a 100-nm-thick AlN membrane suspended above a Pt back refle…
