Upwind embedded boundary SBP operators: New high order numerical schemes for arbitrarily shaped domains with Cartesian grids
Conner Dailey
The paper introduces new high‑order finite‑difference operators that embed irregular boundaries within a regular Cartesian grid, using upwind summation‑by‑parts techniques to impro…

Formulating the complete initial boundary value problem in numerical relativity to model black hole echoes
Conner Dailey, Erik Schnetter, Niayesh Afshordi
In an attempt to simulate black hole echoes (generated by potential quantum-gravitational structure) in numerical relativity, we recently described how to implement a reflecting bo…

Detecting cosmological scalar fields using orbital networks of quantum sensors
Yu Li, Ruolin Liu, Conner Dailey +1
In this Letter, we propose to detect the interaction of a hypothetical coherently evolving cosmological scalar field with an orbital network of quantum sensors, focusing on the GPS…
