Resonance Raman studies of Ni2TIED3+ (TIED = tetraiminoethylenedimacrocycle) reveal that many modes couple to the intense electronic transition centered at 725 nm, a feature that is nominally similar to the intense delocalized intervalence absorption bands observed in the same region for Fe2(TIED)L4(5+) and Ru2(TIED)L4(5+) (L is any of several axial ligands). Time-dependent spectral modeling of...

Odd electron diffraction patterns (EDPs) have been obtained by transmission electron microscopy (TEM) on silicon nanowires grown via the vapour-liquid-solid method and on silicon thin films deposited by electron beam evaporation. Many explanations have been given in the past, without consensus among the scientific community: size artifacts, twinning artifacts or, more widely accepted, the exist...

We present several new eecient architectures to solve the hidden surface problem in the feature domain. All the architectures operate on segments (instead of pix-els) and create a list of visible segments for each scan line. We present two new semi-systolic architectures consisting of an array of M processors, where M is the maximum number of overlapping segments. Both ar-chitectures require pr...

The note describes (100) stacking faults in kyanite from a staurolite-kyanite intergrovrth with a displacement vector R : 7zb. Di-ffraction spots k * 2n are streaked and only with those reflections stacking faults are in contrast, which is interpreted as due to a displacement of thb on the,(100) faults. This produces groups of two corner-sharing tetrahedra. If stacking faults occur periodically...

Unconventional symmetry-breaking phenomena due to nontrivial order parameters attract increasing attention in strongly correlated electron systems. Here, we predict theoretically the occurrence of nanoscale spontaneous spin-current, called spin loop-current (sLC) order, as a promising origin pseudogap and electronic nematicity cuprates. We reveal that sLC is driven by odd-parity electron-hole c...

The properties of the forced oscillations electron-positron plasma (EPP) generated from vacuum under action a short laser pulse are considered. Calculating density conduction and polarization currents within quantum kinetic approach, we demonstrate presence at frequency external field its odd harmonics. It is expected that radiation by these can be observed outside interaction region, for examp...
