Impact of tiny Fermi pockets with extremely high mobility on the Hall anomaly in the kagome metal CsV${}_3$Sb${}_5$

S. Liu, M. Roppongi, M. Kimata +8

The kagome metal CsV${}_3$Sb${}_5$ exhibits an unusual charge-density-wave (CDW) order, where the emergence of loop current order that breaks time-reversal symmetry (TRS) has been prop…
