Anomalous Raman scattering in layered AgCrPSe: Helical modes and excitation energy-dependent intensities
Rahul Rao, Jie Jiang, Ruth Pachter +9
Structural anisotropy in layered two-dimensional materials can lead to highly anisotropic optical absorption which, in turn, can profoundly a^ect their phonon modes. These e^ects i…
Spin-Orbital-Lattice Coupling and the Phonon Zeeman Effect in the Dirac Honeycomb Magnet CoTiO
Thuc T. Mai, Yufei Li, K. F. Garrity +15
The entanglement of electronic spin and orbital degrees of freedom is often the precursor to emergent behaviors in condensed matter systems. With considerable spin-orbit coupling s…
Quantum Hall Transport Measurements of Lateral p-n Junctions Formed via Precise Spatial Photodoping of Graphene/hBN Heterostructures
Son T. Le, Thuc T. Mai, Maria F. Munoz +4
Doped semiconductors are a central and crucial component of all integrated circuits. By using a combination of white light and a focused laser beam, and exploiting hBN defect state…
Ring-Exchange Interaction Effects on Magnons in Dirac Magnet CoTiO
Yufei Li, Thuc T. Mai, M. Karaki +20
The magnetic interactions that determine magnetic order and magnon energies typically involve only two spins. While rare, multi-spin interactions can also appear in quantum magnets…
