Quantum Calculations of the Cavity Shift in Electron Magnetic Moment Measurements
Hannah Day, Roni Harnik, Yonatan Kahn +2
The measurement of the anomalous electron magnetic moment through quantum transitions of a single trapped electron is the most stringent test of quantum field theory. These e…
Hunting axion dark matter with anti-ferromagnets: a case study with nickel oxide
Pier Giuseppe Catinari, Angelo Esposito, Shashin Pavaskar
We show that nickel oxide, which is already a very promising target to look for sub-MeV dark matter scattering, can be employed to hunt axion dark matter, with masses in the meV ra…
An EFT for anisotropic anti-ferromagnets: gapped Goldstones, pseudo-Goldstones, and phase transitions
Pier Giuseppe Catinari, Angelo Esposito, Shashin Pavaskar
We build and discuss a low energy effective field theory for anisotropic anti-ferromagnets in presence of an external magnetic field. Such an effective theory is simple yet rich, a…
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…
