In the geometry associated with equilibrium thermodynamics the scalar curvature Rs is a measure of the volume of correlation, and therefore the singularities of Rs indicates the system instabilities. We explore the use of a similar approach to study

Many bacterial species use flagella for self-propulsion in aqueous media. In the soil, which is a complex and structured environment, water is found in microscopic channels where viscosity and water potential depend on the composition of the soil sol

Electronic density of states for a one-dimensional liquid

We consider a one-dimensional hard rod liquid with an electronic structure of tight-binding type as a simple model for studying the density of states (DOS) in spatially disordered systems. For a finite number of rods, the DOS is exactly obtained by u

Electronic correlations and conductivity for two coupled quantum wires

Autor: Fernando Vericat, Augusto A. Melgarejo

Publikováno v: Physica E: Low-dimensional Systems and Nanostructures. 22:900-905

We study the effect of the interaction between two parallel wires on the electronic correlations and the conductivity of one of them. If the interactions are not singular and the wires are near enough, then we found that the correlations are quickly

Contact correlations of charged fermions in two dimensions and the electron-hole plasma lifetime in semiconductor quantum wells

Publikováno v: Journal of Physics: Condensed Matter. 11:2607-2617

We consider a multicomponent ensemble of charged fermions which are constrained to move on the plane. By just retaining particle-particle ladder diagrams in Goldstone's expression for the energy shift and approximating the kernel of the resultant int
