Cosmic-ray upscattered inelastic dark matter
Nicole F. Bell, James B. Dent, Bhaskar Dutta +4
Light non-relativistic components of the galactic dark matter halo elude direct detection constraints because they lack the kinetic energy to create an observable recoil. However,…
Explaining and using the light mediators of
Bhaskar Dutta, Sumit Ghosh, Peisi Huang +1
Scenarios in which right-handed light Standard Model fermions couple to a new gauge group, can naturally generate a sub-GeV dark matter candidate. But such models nece…
Searching for Dark Photons with Existing Haloscope Data
Sumita Ghosh, Liz Ruddy, Michael J. Jewell +2
The dark (or hidden) photon is a massive U(1) gauge boson theorized as a dark force mediator and as a dark matter candidate. Dark photons can be detected with axion cavity haloscop…
Low-mass inelastic dark matter direct detection via the Migdal effect
Nicole F. Bell, James B. Dent, Bhaskar Dutta +3
We consider searches for the inelastic scattering of low-mass dark matter at direct detection experiments, using the Migdal effect. We find that there are degeneracies between the…
Unified topological characterization of electronic states in spin textures from noncommutative K-theory
Fabian R. Lux, Sumit Ghosh, Pascal Prass +2
The nontrivial topology of spin systems such as skyrmions in real space can promote complex electronic states. Here, we provide a general viewpoint at the emergence of topological…
