Increasing the number of topological nodal lines in semimetals via uniaxial pressure
Abstract The application of pressure has been demonstrated to induce intriguing phase transitions in topological nodal-line semimetals.In this work we analyze RC Toy how uniaxial pressure affects the topological character of BaSn $$_2$$ 2 , a Dirac nodal-line semimetal in the absence of spin-orbit coupling.Using calculations based on the density fu
