Elementary Excitations II: Pair and Collective Excitations

2003
Optical spectroscopies are emerging as particularly promising tools to probe surfaces, since they allow for in situ, non-destructive and real-time monitoring under challenging conditions as may be encountered, for instance, during epitaxial growth.

Collective Excitations in Solids

1983
This book is based on the NATO Advanced Study Institute on ''Collective Excitations in Solids'' held in Italy in 1981. The objective of the Institute was to formulate a unified and coherent treatment of various collective excitation processes by drawing on the current advances in various branches of the physics of the solid state.

Collective plasmon excitations in graphene tubules

Physical Review B, 1996
Due to the inherent simplicity of the graphene tubule systems, it is expected that these systems will become model systems for the calculation of the mechanical and electronic properties of idealized carbon fibers. In this paper the collective electronic excitations on graphene tubules are discussed.

Collective excitations in itinerant spiral magnets

Physical Review B, 1996
We investigate the coupled charge and spin collective excitations in the spiral phases of the two-dimensional Hubbard model using a generalized random-phase approximation. Already for small doping the spin-wave excitations are strongly renormalized due to low-energy particle-hole excitations.

Collective Excitations in Solids

1996
What we call free electrons in a solid are those electrons in the highest occupied energy states, which can migrate freely from atom to atom provided that there are unoccupied states adjacent to the ones they occupy into which they may be excited. These electrons are responsible for most of the electric and magnetic properties of the material. They are
