Dispersion Relations for Dislocation Modes and their Sensitivity to the Lattice Structure
Jin-Yun Lin, Shashin Pavaskar, Ira Z. Rothstein
In this letter we show that the dispersion relation for the dynamical modes of dislocations ("dislons") in solids is sensitive to the lattice symmetries. In particular, we show tha…

Optimal anti-ferromagnets for light dark matter detection
Angelo Esposito, Shashin Pavaskar
We propose anti-ferromagnets as optimal targets to hunt for sub-MeV dark matter with spin-dependent interactions. These materials allow for multi-magnon emission even for very smal…
