Fusion breeders have historically foundered on two coupled obstacles: net electricity forces a large plasma and a large blanket, and a self-sufficient closed fuel cycle at power-plant scale implies a dangerous standing tritium inventory. Both are consequences of demanding electricity from a device whose neutrons are physically its most valuable output. We present the integrated physics of Hyperion, a compact negative-triangularity spherical-tokamak breeder sized to a strategic-materials mission — tritium, helium-3, and 14 MeV neutrons — and show that once the net-electricity requirement is dro

The ever-increasing number of detections of gravitational waves from compact binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever-more sensitive tests of general relativity (GR) in the dynamical and…

We perform the first search for ultralight dark matter using a magnetically levitated particle. A submillimeter permanent magnet is levitated in a superconducting trap with a measured force sensitivity of 0.2 fN/sqrt[Hz]. We find no evidence of a signal and derive limits on dark matter coupled to the difference between baryon and lepton number, B-L, in the mass range (1.10360-1.10485)×10^{-13} eV/c^{2}. Our most stringent limit on the coupling strength is g_{B-L}≲2.98×10^{-21}. We propose the POLONAISE (Probing Oscillations using Levitated Objects for Novel Accelerometry In Searches of Exotic
