Spontaneous Breaking of the SU(3) Flavor Symmetry in a Quantum Hall Valley Nematic

G. Krizman, A. Kazakov, C. -W. Cho +10

Two-dimensional quantum materials can host original electronic phases that arise from the interplay of electronic correlations, symmetry and topology. In particular, the spontaneou…

Deconstruction of the anisotropic magnetic interactions from spin-entangled optical excitations in van der Waals antiferromagnets

Dipankar Jana, Swagata Acharya, Milan Orlita +5

Magneto-optical excitations in antiferromagnetic d systems can originate from a multiplicity of light-spin and spin-spin interactions, as the light and spin degrees of freedom can…

Wide Electrical Tunability of the Valley Splitting in a Doubly gated Silicon-on-Insulator Quantum Well

Nathan Aubergier, Vincent T. Renard, Sylvain Barraud +2

The valley splitting of 2D electrons in doubly-gated silicon-on-insulator quantum wells is studied by low temperature transport measurements under magnetic fields. At the buried th…

Distinct Magneto-Optical Response of Frenkel and Wannier Excitons in CrSBr

Maciej Smiertka, Michal Rygala, Katarzyna Posmyk +10

This study shows that CrSBr hosts Frenkel-like and Wannier-Mott-like excitons whose distinct spatial character explains their contrasting sensitivity to magnetic order and lattice…

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)…
