The fastest Dirac fermions of 1200 km/s with a nodal loop are discovered here in the superconductor ZrPSe, surpassing the velocity record held by the point-node Dirac fermions in graphene. By using angle-resolved photoemission spectroscopy, the authors demonstrate that nonsymmorphic phosphorous-based square nets provide the hoped-for stage for high Dirac velocity, nodal line, and superconductivity to meet together. This finding should pave the way for future fast and low-loss electronics, and hopefully will lead to discovery of the elusive Majorana fermion.

Dirac nodal-line semimetals with one or more closed loops give rise to a surface state that stretches across the topologically nontrivial regions. While these drumhead states have been predicted and explored with simple models, few real materials have been explored experimentally. Here, the authors use quasiparticle interference (QPI) measurements to probe the topologically nontrivial drumhead state spanning occupied and unoccupied states in ZrSiTe, confirming that this state is robust to perturbations like spin-orbit coupling and demonstrating that QPI is a valuable tool to probe drumhead states.
