orthorhombic phase of copper - oxides
A microscopical theory of electronic spectrum and superconductivity is formulated within the two-dimensional anisotropic t − J model with tx = ty and Jx = Jy. Renormalization of electronic spectrum and superconductivity mediated by spin-fluctuations are investigated within the Eliashberg equation in the weak coupling approximation. The gap function has d + s symmetry with the extended s-wave co...
متن کاملPlasmons get tuned up
showing instead non-directional rotation at a much higher speed of rotation. The directional rotation is provoked by the chirality of the STM tip (Fig. 1c)5. In particular, the differences observed for enantiomers on electrical excitation with the same STM tip are attributed to non-identical tip–molecule interactions. The intramolecular vibrational energy redistribution from the high-energy C–H...
متن کاملSpin structures of tetragonal lamellar copper oxides.
The spin Hamiltonian of tetragonal lamellar antiferromagnets is shown to contain several novel anisotropies. Symmetry allows bond-dependent anisotropic exchange interactions, which lead to (a) interplane mean-field coupling and (b) an in-plane anisotropy which vanishes classically but arises from quantum zero point energy (QZPE). A similar QZPE involving the interplane isotropic interaction pre...
متن کاملER Sheets Get Roughed Up
The molecular machinery that shapes the endoplasmic reticulum's (ER's) membrane into ordered networks of "smooth" tubules and "rough" sheets is poorly defined. Shibata et al. (2010) now report that sheet-inducing proteins, such as Climp-63, are enriched in the "rough" ER by their association with membrane-bound ribosomes, whereas curvature-inducing proteins localize at highly bent edges of memb...
متن کاملNanoparticles of copper and copper oxides: Synthesis and Determination of antibacterial activity
Abstract In the present study, nanoparticles of copper and copper oxides were synthesized and their antibacterial activity was evaluated and compared with silver nanoparticles. The nanoparticles were synthesized using facile chemical reactions, and then characterized using field emission scanning microscopy. The nanoparticles were stable for at least two weeks. The...
