Spin fluctuations in a metallic antiferromagnet
Avinash Singh
The magnon energy and amplitude renormalization due to intraband particle-hole excitations are studied in a metallic antiferromagnet. The change in sign of the intraband contributi…

Initial-amplitude dependence in weakly damped oscillators
Avinash Singh
A pedagogically instructive experimental procedure is suggested for distinguishing between different damping terms in a weakly damped oscillator, which highclights the connection b…
