Unconventional free charge in the correlated semimetal Nd2Ir2O7
K. Wang, B. Xu, C. W. Rischau +9
Nd2Ir2O7 is a correlated semimetal with the pyrochlore structure, in which competing spin-orbit coupling and electron-electron interactions are believed to induce a time-reversal s…

Optical signatures of multifold fermions in the chiral topological semimetal CoSi
B. Xu, Z. Fang, M. A. Sánchez-Martínez +12
We report the optical conductivity in high-quality crystals of the chiral topological semimetal CoSi, which hosts exotic quasiparticles known as multifold fermions. We find that th…

Mott transition and collective charge pinning in electron doped Sr2IrO4
K. Wang, N. Bachar, J. Teyssier +7
We studied the in-plane dynamic and static charge conductivity of electron doped Sr2IrO4 using optical spectroscopy and DC transport measurements. The optical conductivity indicate…
