Magneto-optic phonon resonances in magnetic topological EuCd2As2 via helical Raman spectroscopy
Jin Ho Kang, Liangbo Liang, Ioannis Petrides +6
EuCd2As2 materials have two magnetic ordering states: antiferromagnetic (AFM) and ferromagnetic (FM) when their chemical tunability is utilized. While AFM-EuCd2As2 has a nonzero ma…
Plasmon-driven electron-hole pair formation in a non-equilibrium Fermi liquid
Rishi Acharya, Eli Gerber, Nina Bielinski +13
Collective modes in Fermi liquids are usually regarded as dissipation channels that relax electronic excitations through Landau damping. Whether such modes can instead mediate the…
