Higher derivative extensions of 3d3d Chern-Simons models: conservation laws and stability

We consider the class of higher derivative $3d$ vector field models with the field equation operator being a polynomial of the Chern-Simons operator. For $n$-th order theory of this type, we provide a general receipt for constructing $n$-parameter family of conserved second rank tensors. The family includes the canonical energy-momentum tensor, which is unbounded, while there are bounded conserved tensors that provide classical stability of the system for certain combinations of the parameters in the Lagrangian. We also demonstrate the examples of consistent interactions which are compatible with the requirement of stability.Comment: 14 pages, minor correction

Structure and intramolecular mobility of N-(phosporyl)-or (thiophosphoryl)amides and -thioamides: VII.1 Structure and dynamics of N-(Diisopropoxythiophosphoryl)acetamide and -thioacetamide

N-(Diisopropoxythiophosphoryl)acetamide and -thioacetamide occur in solutions as equilibrium mixture of two amide (trans and cis) forms and several tautomers

Structure and intramolecular mobility of N-(thio)phosphoryl(thio)amides: IX1. Structure of N-(diisopropoxyphosphoryl)methylthioamide in solutions by 1H, 13C, and 31P NMR spectroscopy

The structure of N-(diisopropoxyphosphoryl)methylthioamide in CCl4, CD3CN, CD2Cl2, C6D5CD3, and (CD3)2SO solutions was studied by 1H, 13C, and 31P NMR spectroscopy. A tautomeric equilibrium that includes the amide (with trans and cis arrangement of the substituents), thioimide, acylotropic, and phosphorylotropic forms is found

Structure and intramolecular mobility of N-(thio)phosphoryl(thio)amides: XVI. 1H, 13C and 31P NMR study of intramolecular dynamics of N,N′-bis(thio)phosphoryl(thio)urea containing an open-chain fragment in CD2Cl2 and CD3CN solutions

The structure and intramolecular transitions of N,N′-bis[N- disopropoxythiophosphorylaminothiocarbonyl]-1,7-diaminoheptane in CD 2Cl2 and CD3CN 3-10% solutions were studied by means of 1H, 13C, and 31P NMR spectroscopy. Combined analysis of the NMR data confirmed a high lability of the molecules with the realization of two conformational forms of the macromolecule, the amide-amide proton exchange, and existence of various tautomeric forms. © 2011 Pleiades Publishing, Ltd

Structure and intramolecular lability of N-(thio)phosphoryl(thio)amides: VI. 1H, 13C, and 31P NMR interpretation of the phosphorylotropic rearrangement in the N,N′-bis(diisopropoxythiophosphorylaminocarbonyl)-1,10-diaza-18-crown-6 ether in DMSO solution

The phosphorylotropic rearrangement in the N,N'-bis(diisopropoxythiophosphorylaminocarbonyl)-1,10-diaza-18-crown-6 ether in DMSO solution was studied by 1H, 13C, and 31P NMR spectroscopy. The transition from the amide to phosphorylotropic form is accompanied by simultaneous transformation of signals of all structural elements in the 1H, 13C, and 31P NMR spectra

Modelling of free positron states in TiHx

Electron energy structure, positron spectrum and positron characteristics of a-Ti and a-TiH[0.125] were calculated. Self-consistent calculations of the band structure were performed by the linear muffin-tin orbital method in the atomic sphere approximation. Modelling has been made on low content of hydrogen into a-Ti with expanded close-packed hexagonal cell inclusive 8 titanium atoms. Variation of sphere radiuses permitted to consider anisotropy and spherical symmetry of potential. Positron potential and positron wave function were calculated on a base of self-consistent electron density. Then positron probability of existence into TiHx lattice and lifetime were founded. Theoretical calculation indicated a satisfactory agreement of positron characteristics absolute values with the experimental data is achieved but the tendency of values with hydrogen defects increasing is not. The reason of divergence is discussed. On the basis of experimental data and theoretical calculations it was shown that different hydrogen atom states demonstrate the different influence in the lifetime spectra

Structure and molecular lability of N-(thio)phosphoryl(thio)amides: XVII. Intramolecular transformations of N,N′-bis(thio)phosphoryl(thio)ureas with the open-chain fragment in DMSO solution

By means of the 1H, 13C, and 31P NMR spectroscopy structure and intramolecular transformations of N,N′-bis[diisopropoxythiophosphorylaminothiocarbonyl]-1,7-diaminoheptane in 3-10% DMSO solutions were studied. High lability of molecule with the realization of two conformers (linear and pincer-like) of macromolecule, of the proton imide-imide exchange, and of different tautomeric forms was proved. © 2013 Pleiades Publishing, Ltd
