Interacting electrons on a square Fermi surface.
Electronic states near a square Fermi surface are mapped onto quantum chains. Using boson-fermion duality on the chains, the bosonic part of the interaction is isolated and diagonalized. These interactions destroy Fermi liquid behavior. Non-boson interactions are also generated by this mapping, and give rise to a new perturbation theory about the boson problem. A case with strong repulsions bet...

متن کاملStrongly interacting Fermi gases
Measurements have confirmed a theoretical prediction published in 2006: all strongly interacting Fermi gases were predicted to show identical thermodynamic behaviour. Late in 2006, detailed experimental data became available for the first time, for different fermions under different conditions. All the new data lies on a single universal curve, exactly as we predicted. This is an outstanding di...
متن کاملTwo particle correlations and orthogonality catastrophe in interacting Fermi systems
The wavefunction of two fermions, repulsively interacting in the presence of a Fermi sea, is evaluated in detail. We consider large but finite systems in order to obtain an unambiguous picture of the two-particle correlations. As recently pointed out by Anderson, in d ≤ 2 dimensions the particles may be correlated even when situated on the Fermi surface. The ”partial exclusion principle” for tw...
متن کاملBifurcation in kinetic equation for interacting Fermi systems.
The recently derived nonlocal quantum kinetic equation for dense interacting Fermi systems combines time derivatives with finite time stepping known from the logistic mapping. This continuous delay differential equation is a consequence of the microscopic delay time representing the dynamics of the deterministic chaotic system. The responsible delay time is explicitly calculated and discussed f...
