Axion Hair and Pulsar Electrodynamics: modelling, discharge dynamics, and particle-in-cell simulations
Samuel J. Witte, Andrea Caputo, Stefan Stelzl +3
In a companion paper, we demonstrated that static axion field gradients sourced by dense nuclear matter (\emph{axion hair}) can dominate the near-field electrodynamics of old rotat…
Improved Threshold for Particle-Induced Magnetic Avalanche in Single-Molecule Magnets Using Fe Molecule
Bailey Kohn, Rupak Mahapatra, Ivan Borzenets +6
Extending the original work on the development of a magnetic avalanche detector using Mn-ac single-molecule magnet (SMM), we report the results on a significantly lower thre…
Constraints on light QCD and CP-violating axions from the death line of rotation-powered pulsars
Samuel J. Witte, Andrea Caputo, Stefan Stelzl +3
Dense nuclear matter can modify the effective potential of axions, displacing them from their vacuum minimum, and sourcing large external field gradients (``axion hair"). In the ca…
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…
Search for dark matter Particles via Invisible Decays in Sc Nuclear Cascades with a CsI(Tl) Detector
Sharada Sahoo, Jing-han Chen, Mahdi Mirzakhani +3
Dark matter remains one of the most compelling open problems in modern physics, motivating experimental searches for new light, weakly coupled particles beyond the Standard Model.…
Particle Detection Using Magnetic Avalanches in Single-Molecule Magnet Crystals
Bailey Kohn, Hao Chen, Rupak Mahapatra +11
The detection of a single quantum of energy with high efficiency and a low false positive rate is of considerable scientific interest, from serving as single quantum sensors of opt…
