Density instabilities in a two-dimensional dipolar Fermi gas.
We study the density instabilities of a two-dimensional gas of dipolar fermions with aligned dipole moments. The random phase approximation (RPA) for the density-density response function is never accurate for the dipolar gas, and so we incorporate correlations beyond RPA via an improved version of the Singwi-Tosi-Land-Sjölander scheme. In addition to density-wave instabilities, our formalism c...
متن کاملPerturbation Theory around Non–Nested Fermi Surfaces II. Regularity of the Moving Fermi Surface: RPA Contributions
Regularity of the deformation of the Fermi surface under short-range interactions is established for all contributions to the RPA self–energy (it is proven in an accompanying paper that the RPA graphs are the least regular contributions to the self–energy). Roughly speaking, the graphs contributing to the RPA self– energy are those constructed by contracting two external legs of a four–legged g...
متن کاملSoft fermi surfaces and breakdown of Fermi-liquid behavior.
Electron-electron interactions can induce Fermi surface deformations which break the point-group symmetry of the lattice structure of the system. In the vicinity of such a "Pomeranchuk instability" the Fermi surface is easily deformed by anisotropic perturbations, and exhibits enhanced collective fluctuations. We show that critical Fermi surface fluctuations near a d-wave Pomeranchuk instabilit...
متن کاملDensity wave instabilities of fractionalized Fermi liquids
Recent experiments in the underdoped regime of the hole-doped cuprates have found evidence for an incommensurate charge density wave state. We present an analysis of the charge ordering instabilities in a metal with antiferromagnetic correlations, where the electronic excitations are coupled to the fractionalized excitations of a quantum fluctuating antiferromagnet on the square lattice. The re...
متن کاملDynamics and Instabilities of Nuclear Fermi Liquid
The kinetic theory of Fermi liquid is applied to finite nuclei. The nuclear collective dynamics is treated in terms of the observable variables: particle density, current density, pressure etc. The relaxation processes and the development of instabilities in nuclear Fermi-liquid drop are strongly influenced by the Fermi-surface distortion effects. PACS numbers: 21.60.-n,21.60.Ev,24.30Cz Typeset...
