Abstract A spin component analysis of the cumulant (irreducible) density matrices is provided. In particular, the spin‐up spin‐down cumulant density matrix, π , is considered as the most general definition of the Coulomb‐hole density matrix. The local atomic cumulants produced from π , turn out to be the most importan…

In this work, we investigated the release and formation of oxalate during alkaline pulping of southern pine and acacia. The results showed that a significant amount of oxalate is formed during alkaline pulping in addition to the oxalate released from the wood. Acacia was found to have more oxalate in the wood and it a…

Spoof surface plasmon polaritons (SPPs) on a real metal film with periodic cut-through slits are investigated theoretically at terahertz frequencies. For both symmetric and antisymmetric modes of spoof SPPs on the film, the propagation length is severely limited by the absorbing loss in the metal when the fields are h…

The reduction of the polarization charge in a GaN-based single-heterostructure field-effect transistor (HFET) by polarization engineering is proposed as a method for achieving normally off operation. The concept minimizes the dependence of the threshold voltage on the barrier layer thickness. Therefore, thicker gate d…
