Freshly published in Phys. Rev. B.: Higgs and Goldstone spin-wave modes!

Published by Daniel Lacour on

Spontaneous symmetry breaking is ubiquitous in physics. In this paper, we consider a periodic magnetic modulation and observe its Goldstone and Higgs spin wave modes at room temperature using microwave and optical techniques.
This study is the result of a close collaboration between three laboratories: IJL (Nancy), IPCMS (Strasbourg) and OPTIMAS (TU Kaiserslautern), in the framework of the SWANGATE project (ANR-16-CE24-0027).
