Pomeranchuk instability: symmetry breaking and experimental signatures
نویسنده
چکیده
We discuss the emergence of symmetry-breaking via the Pomeranchuk instability from interactions that respect the underlying point-group symmetry. We use a variational mean-field theory to consider a 2D continuum and a square lattice. We describe two experimental signatures: a symmetry-breaking pattern of Friedel oscillations around an impurity; and a structural transition.

The purpose of this research is to provide a deeper understanding of the planar high- symmetry configuration instability. In the ideal case, the distortion corresponds to the movements of nuclei along normal modes that belong to non-totally symmetric irreps of the high symmertry (HS) point group of molecule. The analysis of the structural distortion from the HS nuclear arrangements of the JT ac...

The Turing instability has now been established as a canonical mechanism of stationary pattern formation both theoretically as well as experimentally. In this brief article the basic theory of this instability will be sketched, with special emphasis on the characteristics it has in common with symmetry breaking in equilibrium systems. A very brief introduction to some experimental and numerical...

To the memory of my first teacher Isaak Yakovlevich Pomeranchuk. Abstract The main features of QCD, e.g. confinement, chiral symmetry breaking, Regge trajectories are naturally and economically explained in the framework of the Field Correlator Method (FCM). The same method correctly predicts the spectrum of hybrids and glueballs. When applied to DIS and high-energy scattering it leads to the i...
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...
