Undergrad What Are the Implications of Discovering Semi-Dirac Fermions in ZrSiS?

SUMMARY

The recent paper by Shao, Y., Moon, et al. (2024) published in Physical Review X, volume 14, issue 4, article 041057, presents evidence of semi-Dirac fermions in the material ZrSiS. These fermions exhibit a linear dispersion relation in one direction while displaying a quadratic relationship in the other two, leading to the interpretation that they possess mass along certain axes. The discovery raises questions about the potential for similar phenomena in two-dimensional materials and their practical applications, prompting further discussion on existing theories regarding semi-Dirac fermions.

Recent paper is making a buzz for having found evidence of semi-Dirac fermions in ZrSiS:
These fermions have a linear dispersion relation in one direction but quadratic in the other two (thus some news articles saying that it has mass only along some axes). Of course now the speculation is if one can do the same in 2D materials and find some applications. Anybody here has any insight on previous theories about semi-Dirac fermions? I leave this thread open for discussion of the paper.
