Origin of multiple Lifshitz transitions in the Weyl semi-metal RhSi
Krishnendu Patra, Viktor Christiansson, Ferdi Aryasetiawan +1
It is known from density functional theory (DFT) calculations that RhSi has a multifold degenerate Dirac point at the Fermi energy, with the dominant states in the low-energy regio…
