Searching for ultralight bosons with Josephson junction interferometry
Djuna Croon, Tanmay Kumar Poddar
Ultralight bosons sourced by macroscopic objects can generate long-range spin-independent and spin-dependent potentials that are accessible to precision interferometry. Such potent…
Searching for axions with quantum interferometry
Tanmay Kumar Poddar, Michael Spannowsky
Quantum phase measurements offer a complementary route to axion searches. We show that axion-photon interactions can imprint both Aharonov-Bohm (AB) and Berry phases in experimenta…
Microscopic primordial black holes as macroscopic dark matter from large extra dimensions
Giuseppe Filiberto Vitale, Gaetano Lambiase, Tanmay Kumar Poddar +1
We study the coupled cosmological evolution of primordial black holes (PBHs) and radiation in the Arkani-Hamed-Dimopoulos-Dvali (ADD) framework with large extra dimensions and…
Illuminating the dark universe in the multi-messenger era
Philippe Brax, Anne-Christine Davis, Md Riajul Haque +8
The precision era of multi-messenger astronomy, together with modern astrophysical, cosmological, and gravitational wave observations, increasingly points toward the existence of a…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Searching for axions with time resolved pulsar polarimetry
Francesca Chadha-Day, Tanmay Kumar Poddar
Pulsars possess strong dipole magnetic fields that can source axion fields through the axion-photon interaction. Pulsars may therefore be surrounded by axion field configurations o…
Ultralight time-oscillating scalars from magnetized compact stars: electrophilic radiation and photon propagation effects
Tanmay kumar Poddar, Gaetano Lambiase
Ultralight scalars with electrophilic couplings to the time-dependent Goldreich-Julian charge density of magnetized compact stars can be radiated from their magnetospheres, contrib…
Photon-dark photon oscillation in M87 and Crab Nebula environments
Tanmay Kumar Poddar, Sourov Roy, Pratick Sarkar
Compact astrophysical systems such as neutron stars and black holes provide powerful laboratories for testing feebly coupled dark photons (DPs). We investigate light DPs kineticall…
