Inferring neutron star properties with continuous gravitational waves

• Neil Lu

Neutron stars are astrophysically interesting objects, but very little is understood about their interior physics. I discuss a new framework which would use a future continuous gravitational wave detection to infer a neutron star’s moment of inertia, equatorial ellipticity, and the component of the magnetic dipole moment perpendicular to its rotation axis. I also discuss the errors that associated with such an inference and its applicability for constraining the neutron star equation of state.

Gotta stretch em’all: single photons from single layers

• Giuseppe Ronco

Single photons, individual quanta of the propagating electromagnetic field, serve as excellent quantumness suppliers for quantum communication. Existing single photon sources offer high-quality properties, but they require large working platforms or cryogenic temperatures. As our ability to harness the potential of the quantum realm grows, there is a growing demand for scalable devices. Two-dimensional materials, which are crystals thinned down to a single layer, hold promise in meeting this challenge. Their remarkable flexibility enables us to exploit deformation to tailor their optical and electrical properties. Moreover, they emit single photons if strained, offering a versatile platform for future scalable devices. Thus, what are we waiting for? Gotta stretch 'em all!
