Limits on the abundance of millicharged particles bound to matter
Gadi Afek, Fernando Monteiro, Jiaxiang Wang +3
Millicharged particles (mCPs) are hypothesized particles possessing an electric charge that is a fraction of the charge of the electron. We report a search for mCPs with charges $\…
Driving spin chirality by electron dynamics in laser-excited antiferromagnets
Sumit Ghosh, Frank Freimuth, Olena Gomonay +2
Optical generation of complex spin textures is one of the most exciting challenges of modern spintronics. Here, we uncover a distinct physical mechanism for imprinting spin chirali…
A quantum-enhanced search for dark matter axions
K. M. Backes, D. A. Palken, S. Al Kenany +21
In dark matter axion searches, quantum uncertainty manifests as a fundamental noise source, limiting the measurement of the quadrature observables used for detection. We use vacuum…
Opportunities for probing with light mediators
Bhaskar Dutta, Sumit Ghosh, Jason Kumar
We consider strategies for using new datasets to probe scenarios in which light right-handed SM fermions couple to a new gauge group, . This scenario provides a natural…
Explaining the XENON1T excess with Luminous Dark Matter
Nicole F. Bell, James B. Dent, Bhaskar Dutta +3
We show that the excess in electron recoil events seen by the XENON1T experiment can be explained by relatively low-mass Luminous Dark Matter candidate. The dark matter scatters in…
Explaining , the KOTO anomaly and the MiniBooNE excess in an extended Higgs model with sterile neutrinos
Bhaskar Dutta, Sumit Ghosh, Tianjun Li
We consider a simple extension of the Standard Model (SM) by a complex scalar doublet and a singlet along with three sterile neutrinos. The sterile neutrinos mix with the SM neutri…
