Abstract: We determined how Li doping affects the Ni/Mn ordering in high-voltage spinel LiNi0.5Mn1.5O4(LNMO) by using neutron diffraction, TEM image, electrochemical measurements, and NMR data. The doped Li occupies empty octahedral interstitials (16c site) before the… read more here.

Abstract: The lattice effect on the charge ordering in La1/3Sr2/3FeO3−δ is addressed by calcium ion substitution. Cation disorder effect due to size differences between A-site La3+, Sr2+, and Ca2+ has been found in La1/3(Sr1-xCax)2/3FeO3−δ perovskites. Below… read more here.

DOI: 10.1103/physrevd.95.074503
Abstract: The Dirac operator in finite temperature QCD is equivalent to the Hamiltonian of an unconventional Anderson model, with on-site noise provided by the fluctuations of the Polyakov lines. The main features of its spectrum and… read more here.
