Tunability of multiple ultraflat bands and effect of spin-orbit coupling in twisted bilayer transition metal dichalcogenides Zhen Zhan, Yipei Zhang, Pengfei Lv, Hongxia Zhong, Guodong Yu, Francisco Guinea, José Ángel Silva-Guillén, and Shengjun Yuan Phys. Rev. B 102, 241106(R) - Published 7 December 2020. The competition between spin-orbit-coupling and Jahn-Teller stabilizations is dramatically illustrated by the system NiFe t Cr 2-t O 4. Whereas superexchange energies maintain a Jahn-Teller stabilization below T c in CuCr 2 O 4 , despite collinear Cu 2+ -ion spins, magnetostrictive distortions below T N occur in FeO and CoO. Elastic restoring forces favor. Moreover, the realization in 2008 that a novel variant of the classic Mott metal-insulator transition was at play in Sr2IrO4 provided the impetus for a burgeoning group of studies of the influence of strong spin-orbit interactions in “heavy” (4d- and 5d-) transition-element oxides.

Much of the interesting physics requires spin-orbit coupling energies of the order of hundreds of meV, i.e. comparable to electronic band energy scales. Hence, this is irrelevant to many materials. But the spin-orbit coupling can be quite strong in 5d transition metals. Iridates (iridium oxides) may be model compounds to realise this physics. Monolayer transition-metal dichalcogenide (TMD) superconductors in particular lack inversion symmetry, yielding an antisymmetric form of spin–orbit coupling that admits both spin-singlet and spin-triplet components of the superconducting wavefunction. Here, we present an experimental and theoretical study of two intrinsic TMD superconductors.
