Evidence for rare-region physics in the structural and electronic degrees of freedom of the nickelate La $_{2 - x}$ Sr $_{x}$ NiO $_{4}$

R. J. Spieker, B. Krohnke, D. Zhai +11

We present a diffuse neutron and x-ray scattering study of structural as well as spin- and charge-density-wave fluctuations in the electrical insulator La $_{2 - x}$ Sr $_{x}$ NiO $_{4}$ . Thi…

Uniaxial strain tuning of polar lattice vibrations in KTaO $_{3}$ and SrTiO $_{3}$

I. Khayr, N. Somun, S. Hameed +11

The interplay of electronic and structural degrees of freedom is a prominent feature of many quantum materials and of particular interest in systems with strong ferroelectric fluct…

Pervasive symmetry-lowering nanoscale structural fluctuations in the cuprate La $_{2 - x}$ Sr $_{x}$ CuO $_{4}$

R. J. Spieker, M. Spaić, I. Khayr +12

The cuprate superconductors are among the most widely studied quantum materials, yet there remain fundamental open questions regarding their electronic properties and the role of t…
