Strong correlations and spin-density-wave phase induced by a massive spectral weight redistribution in $\\\ensuremath{\\\alpha}{ext{-Fe}}_{1.06}ext{Te}$ The electronic structure of alpha-Fe1.06Te is studied with angle-resolved photoemission spectroscopy. We show that there is substantial spe...
In AC power transmission the terms multiphase and polyphase are applied to currents that are out of phase with one another. In a two-phase system there are two currents with a phase-angle difference of 90°; in a three-phase system the currents differ in phase angle by 120°. This ...

While it is not straightforward to identify the phase shift by diffraction techniques such as the neutron scattering and the resonant x-ray scattering, our findings suggest that the angle-resolved photoemission spectroscopy and transport measurements will give good probes to detect the phase shift and...
in the chiral limit. Heavy baryon chiral perturbation theory (HBChPT) was proposed and developed to solve the power-counting problem that occurs in baryon ChPT [4,5,6]. Many achievements have been obtained in the light flavor hadronic physics using SU(2) HBChPT [7,8,9,10,11,12,13,14...

Many ultrafast phenomena in biology and physics are fundamental to our scientific understanding but have not yet been visualized owing to the extreme speed and sensitivity requirements in imaging modalities. Two examples are the propagation of passive cu
In addition, coherent electron-induced radiation pattern from the flake is a dipolar one40 such that angle-resolved spectroscopy is required to fully capture the mutual coherence between EDPHS and sample radiation. Hence, the interference patterns in both momentum and energy space are characterized, ...
