Semi-Dirac Fermions Found in ZrSiS: Quasiparticles with Directional Mass Behavior
Researchers at Penn State and Columbia University identified semi-Dirac fermions, quasiparticles theorized 16 years ago, in ZrSiS crystals. These particles are massless in one direction but have mass in another. The findings, published in Physical Review X, were made using magneto-optical spectroscopy at the National High Magnetic Field Laboratory. The discovery could...
