Prediction of three-fold fermions in a nearly-ideal Dirac semimetal BaAgAs
Sougata Mardanya, Bahadur Singh, Shin-Ming Huang +5
Materials with triply-degenerate nodal points in their low-energy electronic spectrum produce crystalline-symmetry-enforced three-fold fermions, which conceptually lie between the…

Starfruit-like nodal semimetal to Dirac and Weyl semimetal state in CaAuAs
Bahadur Singh, Sougata Mardanya, Chenliang Su +3
Band-crossings occurring on a mirror plane are compelled to form a nodal loop in the momentum space without spin-orbit coupling (SOC). In the presence of other equivalent mirror pl…
