Nonlinear Terahertz Electroluminescence from Dirac Landau Polaritons
B. Benhamou-Bui, C. Consejo, S. S. Krishtopenko +15
We report Dirac Landau polaritons observed by terahertz (THz) magnetoreflectivity spectroscopy, demonstrating strong coupling between cyclotron transitions of two-dimensional (2D)…

Low-energy excitations in multiple modulation-doped CdTe/(CdMg)Te quantum wells
D. Yavorskiy, F. Le Mardelé, I. Mohelsky +6
Low energy excitations of a two-dimensional electron gas (2DEG) in modulation-doped multiple (ten) quantum wells (QWs) was studied using far-infrared magneto-transmission technique…

Transverse and longitudinal magnons in strongly anisotropic antiferromagnet FePSe3
F. Le Mardele, A. El Mendili, M. E. Zhitomirsky +7
FePSe3 is a collinear honeycomb antiferromagnet with an easy-axis anisotropy and large spins S=2. It belongs to a family of magnetic van der Waals materials, which recently attract…
