Spin-chiral electron-phonon coupling in metallic strontium titanate
N. Somun, L. RogiÄ, I. Khayr +12
Electron-phonon coupling (EPC) - the interaction between conduction electrons and quantized atomic vibrations - plays a central role in condensed matter physics and determines some…
Tuning charge-transport properties and magnetic order in metallic EuTiO
Xing He, Chiou Yang Tan, Issam Khayr +9
The stoichiometric antiferromagnetic insulator EuTiO is proximate to a ferroelectric phase. Whereas cation substitution has been used as a tuning parameter to introduce charge…
Uniaxial strain tuning of polar lattice vibrations in KTaO and SrTiO
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…
Nature of the ferromagnet-paramagnet transition in YCaTiO
S. Hameed, I. Khayr, J. Joe +8
Neutron scattering, magnetometry, and muon spin rotation (SR) measurements were performed to investigate the magnetic order and spin dynamics across the ferromagnet-to-paramagn…
Pervasive symmetry-lowering nanoscale structural fluctuations in the cuprate LaSrCuO
R. J. Spieker, M. SpaiÄ, 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…
In-plane anisotropy of charge density wave fluctuations in 1-TiSe
Xuefei Guo, Anshul Kogar, Jans Henke +17
We report measurements of anisotropic triple- charge density wave (CDW) fluctuations in the transition metal dichalcogenide 1-TiSe over a large volume of reciprocal space…
