Topological Singularity Induced Chiral Kohn Anomaly in a Weyl Semimetal
Thanh Nguyen, Fei Han, Nina Andrejevic +16
The electron-phonon interaction (EPI) is instrumental in a wide variety of phenomena in solid-state physics, such as electrical resistivity in metals, carrier mobility, optical tra…
Soft antiphase tilt of oxygen octahedra in the hybrid improper multiferroic Ca3Mn1.9Ti0.1O7
Feng Ye, Jinchen Wang, Jieming Sheng +13
We report a single crystal neutron and x-ray diffraction study of the hybrid improper multiferroic Ca3Mn1.9Ti0.1O7 (CMTO), a prototypical system where the electric polarization ari…
Low-energy phonons in BiSrCaCuO and their possible interaction with electrons measured by inelastic neutron scattering
A. M. Merritt, J. -P. Castellan, T. Keller +4
Electron-phonon interaction in copper oxide superconductors is still enigmatic. Strong coupling for certain optic phonons is now well established experimentally, but theoretical un…
Magnetism in nanoparticle LaCoO3
A. M. Durand, D. P. Belanger, F. Ye +4
LaCoO3 (LCO) nanoparticles were synthesized and their magnetic and structural properties were examined using SQUID magnetometery and neutron diffraction. The nanoparticles exhibit…
Double neutron spin resonances and gap anisotropy in underdoped superconducting NaFe0.985Co0.015As
Chenglin Zhang, Rong Yu, Yixi Su +8
We use inelastic neutron scattering to show that superconductivity in electron-underdoped NaFe0.985Co0.015As induces a dispersive sharp resonance near Er1 = 3:25 meV and a broad di…
Origins of large enhancement in electromechanical coupling for nonpolar directions in ferroelectric BaTiO3
A. Pramanick, S. O. Diallo, O. Delaire +4
The origins of enhanced piezoelectric coupling along nonpolar crystallographic directions in ferroelectric BaTiO3 are investigated using in situ neutron spectroscopy. It is observe…
