Topological materials can yield quasiparticles that behave in a manner similar to elementary particles that are part of the standard model of particle physics. In this paper, published in Physical Review X, we report on a new class of such quasiparticles—triple point fermions—which represent fermions that have mixed properties of Dirac and Weyl fermions. The triple point fermions exhibit a variety of observable phenomena, including anomalous responses to magnetic fields that can possibly be used in future devices. We expect our results to pave the way for future studies that identify topological materials with technologically interesting properties.
