Stripe order, depinning, and fluctuations in La${}_{1.875}$Ba${}_{0.125}$CuO${}_4$ and La${}_{1.875}$Ba${}_{0.075}$Sr${}_{0.050}$CuO${}_4$

We present a neutron scattering study of stripe correlations measured on a single crystal of La${}_{1.875}$Ba${}_{0.125}$CuO${}_4$. Within the low-temperature-tetragonal (LTT) phase, s…
