Topological Insulators

Our group works on topological classification of semi-metals using experimental and DFT simulations. Topological semi-metals are classified as a quantum phase of matter, which host Dirac and Weyl fermions. The researchers working in quantum matter physics group study these semi-metals under very low temperature, high magnetic field and high pressures using various transport experiments. The materials which we are working now are rare earth based Half Heusler alloy, which has a general formula XYZ. X can be any rare earth element like Dy, Er, Y etc., Y is generally transition element Pd, Pt, Au and Z is usually heavy element providing SOC like. Bi, Sb, etc.
