Evidence for strong lattice effects as revealed from huge unconventional oxygen isotope effects on the pseudogap temperature in La${}_{2-x}$Sr${}_x$CuO${}_4$

The oxygen isotope (${}^{16}$O/${}^{18}$O) effect (OIE) on the pseudogap (charge-stripe ordering) temperature $T^{\ast }$ is investigated for the cuprate superconductor La${}_{2-x}$Sr$_{x…
