On the Speed-up of Wave-like Dark Matter Searches with Entangled Qubits
Arushi Bodas, Sohitri Ghosh, Roni Harnik
Qubit-based sensing platforms offer promising new directions for wave-like dark matter searches. Recent proposals demonstrate that entangled qubits can achieve quadratic scaling of…
Anisotropic Gravitational Waves from Anisotropic Axion Rotation
Arushi Bodas, Keisuke Harigaya, Keisuke Inomata +2
Gravitational waves (GWs) provide a powerful probe of the early universe due to their ability to free-stream across cosmic history. We study GW production in a compelling scenario…
Charged Loops at the Cosmological Collider with Chemical Potential
Arushi Bodas, Edward Broadberry, Raman Sundrum +1
Cosmological collider physics allows the detection of heavy particles at inflationary scales through their imprints on primordial non-Gaussianities. We study the chemical potential…
Acoustic Misalignment Mechanism for Axion Dark Matter
Arushi Bodas, Raymond T. Co, Akshay Ghalsasi +2
A rotation in the field space of a complex scalar field corresponds to a Bose-Einstein condensation of charges. We point out that fluctuations in this rotating condensate ex…
The Scalar Chemical Potential in Cosmological Collider Physics
Arushi Bodas, Soubhik Kumar, Raman Sundrum
Non-analyticity in co-moving momenta within the non-Gaussian bispectrum is a distinctive sign of on-shell particle production during inflation, presenting a unique opportunity for…
