Minimum lifetime of a black hole
Eugenio Bianchi, Matthew Brandsema, Kenneth Czuprynski +1
We derive bounds on the lifetime of an evaporating black hole. The bound follows from energy conservation and purification, within the framework of `asymptotically semiclassical sp…
Cyclotron Radiation Signal Characterization in Resonant Cavities for the Project 8 Neutrino Mass Experiment
A. Ashtari Esfahani, S. Bhagvati, H. P. Binney +60
Many experimental methods in physics require understanding radiation from single particles into non-trivial electromagnetic mode structures. Such characterization is critical for C…
Leveraging Plasmonic Nanocavity Arrays Forming Metasurfaces to Boost Second Harmonic Generation due to Surface Effects
Sky Semone, Matthew J. Brandsema, Thang Hoang +1
Plasmonic metasurfaces have emerged as a promising platform for enhancing a range of nonlinear optical processes, offering compact geometry and flexibility in light manipulation. S…
Dynamics of Magnetic Evaporative Beamline Cooling for Preparation of Cold Atomic Beams
A. Ashtari Esfahani, S. Bhagvati, S. Böser +55
The most sensitive direct neutrino mass searches today are based on measurement of the endpoint of the beta spectrum of tritium to infer limits on the mass of the unobserved neutri…
Chiral Spontaneous Photon-Pair Generation with Plasmonic Bound States in the Continuum
Sky Semone, Matthew J. Brandsema, Christos Argyropoulos
Spontaneous parametric down conversion (SPDC) has proven to be a robust and prominent method for creating non-classical light sources of entangled single-photon pairs. However, suc…
Antenna Arrays for CRES-based Neutrino Mass Measurement
A. Ashtari Esfahani, S. Bhagvati, S. Böser +65
CRES is a technique for precision measurements of kinetic energies of charged particles, pioneered by the Project 8 experiment to measure the neutrino mass using the tritium endpoi…
