Searching for heavy charged relics in the Earth
Reza Ebadi, Peter W. Graham, Surjeet Rajendran +2
We propose a method for detecting an ambient density of heavy, electrically-charged particles. Such particles would impact the Earth, lose energy in terrestrial matter, and become…
Measuring Pulsar Distances from Chirping Orbital Periods
Brady Egleston, Reza Ebadi, Ronald Walsworth
The observed orbital period time derivative (or orbital "chirp") of a millisecond binary pulsar (MSP) encodes information about both the intrinsic properties of the binary system a…
Gravothermal Pile-Up of Collisional Dark Matter Around Compact Objects
Reza Ebadi, Erwin H. Tanin
The dark matter may consist of multiple species that interact differently. We show that a species that is cosmologically subdominant but highly collisional can pile up and become d…
LISA double white dwarf binaries as Galactic accelerometers
Reza Ebadi, Vladimir Strokov, Erwin H. Tanin +2
Galactic double white dwarf (DWD) binaries are among the guaranteed sources for the Laser Interferometer Space Antenna (LISA), an upcoming space-based gravitational wave (GW) detec…
GALILEO: Galactic Axion Laser Interferometer Leveraging Electro-Optics
Reza Ebadi, David E. Kaplan, Surjeet Rajendran +1
We propose a novel experimental method for probing light dark matter candidates. We show that an electro-optical material's refractive index is modified in the presence of a cohere…
Rydberg Single Photon Detection for Probing 0.1-10 meV Dark Matter with BREAD
Abhishek Banerjee, Reza Ebadi, Surjeet Rajendran
We introduce a Rydberg-based single photon detector (SPD) for probing dark matter in the 0.1-10 meV mass range (20 GHz-2 THz). The Rydberg SPD absorbs photons produced and focused…
