Strong electron-phonon coupling driven pseudogap modulation and density-wave fluctuations in a correlated polar metal

H Wang, Y **ong, H Padma, Y Wang, Z Wang… - Nature …, 2023 - nature.com
There is tremendous interest in employing collective excitations of the lattice, spin, charge,
and orbitals to tune strongly correlated electronic phenomena. We report such an effect in a …

Structural phase diagram for Sm-substituted multiferroics

V Petkov, A Zafar, L Gallington, S Shastri, B Aoun - Physical Review Materials, 2024 - APS
The structural evolution of Sm substituted BiFe O 3 is studied by total x-ray scattering and
structure modeling. It is shown that the crystal structure changes from polar to antipolar and …

Metal-insulator transition in originating in an anomalous lattice effect

S Purwar, S Paul, K Vijay, R Venkatesh, S Banik… - Physical Review B, 2025 - APS
We present a comprehensive investigation of the structural, electrical transport, and
magnetic properties of FeSe x (x= 1.14, 1.18, 1.23, 1.28, and 1.32) to unravel the mechanism …

Local lattice distortions and electronic phases in perovskite manganite Pr0. 5Sr0. 5MnO3

A Zafar, V Petkov, AMM Abeykoon - Journal of Physics: Materials, 2024 - iopscience.iop.org
We use variable temperature and magnetic field total x-ray scattering to study the crystal
structure of the strongly correlated Pr 0.5 Sr 0.5 MnO 3 perovskite, which is a paramagnetic …
