Electronic phases of low dimensional conductors
We briefly review the physics of electronic phases in low dimensional conductors. We begin by introducing the properties of the one-dimensional electron gas model using bosonization and renormalization group methods.We then tackle the influence of interchain coupling and go through the different instabilities of the electron system to the formation of higher dimensional states. The connection w...
متن کاملLow-dimensional electronic states at silicon surfaces
Self-assembled atomic chains can be triggered at stepped Si(111) surfaces by adding sub-monolayer amounts of metals, such as gold, silver, platinum, alkali metals, alkaline earths, and rare earths. A common feature of all these structures is the honeycomb chain, a graphitic strip of Si atoms at the step edge that is lattice matched in the direction parallel to the edge but completely mismatched...
متن کاملLow Dimensional Hamiltonian Systems
The theory of differential forms began with a discovery of Poincaré who found conservation laws of a new type for Hamiltonian systems—The Integral Invariants. Even in the absence of non-trivial integrals of motion, there exist invariant differential forms: a symplectic two-form, or a contact one-form for geodesic flows. Some invariant forms can be naturally considered as “forms on the quotient....
متن کاملPressure-induced electronic topological transitions in low dimensional superconductors
The high-Tc cuprate superconductors are characterized by a quasitwo-dimensional layered structure where most of the physics relevant for high-Tc superconductivity is believed to take place. In such compounds, the unusual dependence of critical temperature Tc on external pressure results from the combination of the nonmonotonic dependence of Tc on hole doping or hole-doping distribution among in...
متن کاملHot electrons in low-dimensional phonon systems
A simple bulk model of electron-phonon coupling in metals has been partially successful in explaining experiments on metal films that actually involve surfaceor other low-dimensional phonons. However, by an exact application of this standard model to a semi-infinite substrate with a free surface, making use of the actual vibrational modes of the substrate, we show that such agreement is fortuit...
