A Semi-Classical Schwinger-Keldysh Re-interpretation Of The 4D Majorana Fermion Mass Term

We offer a semi-classical re-interpretation of the 4D Majorana fermion mass term as an `influence action' in the Schwinger-Keldysh formulation of fermionic Quantum Field Theories.Comment: 4 pages. Comments welcom

JAVANESE CULTURE DEPICTED IN THE USE OF KINSHIP ADDRESS TERMS

The Javanese system of kinship terms of address relies tightly on its social construction mirroring not only culture but also point of view of the Javanese people. It is undeniable that the society has long been structured vertically hierarchical. There is always upper to lower social relationship among social practices. Hence it is manifested in the form of Javanese speech levels illustrating that a speaker should consider both role and circumstance. The levels of speech presumably fall into some smaller linguistic features, one of which is address term particularly maintaining kinship relationship. Javanese culture considers ascending generation as the polar asserting that father’s/mother’s big brothers/sisters, father’s/mother’s big brother’s/sister’s sons/daughters, father’s/mother’s big brother’s/sister’s son’s/daughter’s sons/daughters would be addressed as all terms equivalent to big or older sibling

The New Resonating Valence Bond Method for Ab-Initio Electronic Simulations

The Resonating Valence Bond theory of the chemical bond was introduced soon after the discovery of quantum mechanics and has contributed to explain the role of electron correlation within a particularly simple and intuitive approach where the chemical bond between two nearby atoms is described by one or more singlet electron pairs. In this chapter Pauling's resonating valence bond theory of the chemical bond is revisited within a new formulation, introduced by P.W. Anderson after the discovery of High-Tc superconductivity. It is shown that this intuitive picture of electron correlation becomes now practical and efficient, since it allows us to faithfully exploit the locality of the electron correlation, and to describe several new phases of matter, such as Mott insulators, High-Tc superconductors, and spin liquid phases
