Spatially periodic states in a strongly dipolar mixture Open
We demonstrate the formation of a novel eigenstate in a strongly dipolar binary $^{164}$Dy-$^{162}$Dy mixture, where the inter- and intraspecies dipolar lengths are larger than the corresponding scattering lengths. When this mixture is con…
