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…
Bound States in Second-order Topological Graphitic Structures
Haiyue Huang, Prineha Narang, Ioannis Petrides
Quadrupole insulators are a class of second-order topological insulators (SOTIs) that host zero-dimensional corner states within a two-dimensional bulk. Despite their unique proper…
