Dynamics of a heavy particle in a Luttinger liquid
A. H. Castro Neto, Matthew P. A. Fisher
We study the dynamics of a heavy particle of mass moving in a one-dimensional repulsively interacting Fermi gas. The Fermi gas is described using the Luttinger model and bosoni…
Landau theory of phase separation in cuprates
A. H. Castro Neto
I discuss the problem of phase separation in cuprates from the point of view of the Landau theory of Fermi liquids. I calculate the rate of growth of unstable regions for the hydro…
The mobility and diffusion of a particle coupled to a Luttinger liquid
A. H. Castro Neto, A. O. Caldeira
We study the mobility of a particle coupled to a one dimensional interacting fermionic system, a Luttinger liquid. We bosonize the Luttinger liquid and find the effective interacti…
Bosonization of Fermi liquids
A. H. Castro Neto, Eduardo Fradkin
We bosonize a Fermi liquid in any number of dimensions in the limit of long wavelengths. From the bosons we construct a set of coherent states which are related with the displaceme…
Bosonization of the Low Energy Excitations of Fermi Liquids
A. H. Castro Neto, Eduardo Fradkin
We bosonize the low energy excitations of Fermi Liquids in any number of dimensions in the limit of long wavelengths. The bosons are coherent superposition of electron-hole pairs a…
