Thermoelectric and optical probes for a Fermi surface topology change in noncentrosymmetric metals

Sonu Verma, Tutul Biswas, Tarun Kanti Ghosh

Noncentrosymmetric metals such as Li${}_2$(Pd${}_{1-x}$Pt${}_x$)${}_3$B have different Fermi surface topology below and above the band touching point where spin-degeneracy is not lifted by…
