New Limit on Dark Photon Kinetic Mixing in the 0.2-1.2 $\boldsymbol{\mu}$eV Mass Range From the Dark E-Field Radio Experiment

Autor: Levine, Joseph, Godfrey, Benjamin, Tyson, J. Anthony, Tripathi, S. Mani, Polin, Daniel, Aminaei, Amin, Kolner, Brian H., Stucky, Paul

We report new limits on the kinetic mixing strength of the dark photon spanning the mass range 0.21 -- 1.24 $\mu$eV corresponding to a frequency span of 50 -- 300 MHz. The Dark E-Field Radio experiment is a wide-band search for dark photon dark matte

Investment AUM Fee Costs: Evaluating a Simple Formula

Autor: Levine, Joseph

How much do financial management fees cost investors? This article studies an approximate formula for the cumulative costs of annual Assets Under Management (AUM) fees. The formula states that an investment paying an annual fee of $\epsilon$% of AUM

Publikováno v: Phys. Rev. D 104, 012013 (2021)

We are building an experiment to search for dark matter in the form of dark photons in the nano- to milli-eV mass range. This experiment is the electromagnetic dual of magnetic detector dark radio experiments. It is also a frequency-time dual experim
