NMR evidence for static local nematicity and its cooperative interplay with low-energy magnetic fluctuations in FeSe under pressure
P. Wiecki, M. Nandi, A. E. Böhmer +3
We present Se-NMR measurements on single-crystalline FeSe under pressures up to 2 GPa. Based on the observation of the splitting and broadening of the NMR spectrum due to st…
Volovik Effect and Fermi-Liquid Behavior in the s-Wave Superconductor CaPd2As2: 75As NMR-NQR Measurements
Q. -P. Ding, P. Wiecki, V. K. Anand +4
The electronic and magnetic properties of the collapsed-tetragonal CaPdAs superconductor (SC) with a transition temperature of 1.27 K have been investigated by As nu…
Coexistence of antiferromagnetic and ferromagnetic spin correlations in SrCo2As2 revealed by 59Co and 75As NMR
P. Wiecki, V. Ogloblichev, Abhishek Pandey +2
In nonsuperconducting, metallic paramagnetic SrCo2As2, inelastic neutron scattering measurements have revealed strong stripe-type (q) = (,0) antiferromagnetic (AFM) spin corr…
Non-perturbative Calculation of the Positronium Mass Spectrum in Basis Light-Front Quantization
Paul Wiecki, Yang Li, Xingbo Zhao +2
We report on recent improvements to our non-perturbative calculation of the positronium spectrum. Our Hamiltonian is a two-body effective interaction which incorporates one-photon…
