Luttinger sum rules and spin fractionalization in the SU(N) Kondo lattice
We show how Oshikawa's theorem for the Fermi surface volume of the Kondo lattice can be extended to the SU(N) symmetric case. By extending the theorem, we can show that the mechanism of Fermi surface expansion seen in the large N mean-field theory is ...

Nonlinear bosonization of Fermi surfaces: The method of coadjoint orbits
We develop a method for bosonizing the Fermi surface based on the formalism of the coadjoint orbits. This allows one to parametrize the Fermi surface by a bosonic field that depends on the spacetime coordinates and on the position on the Fermi surface ...

In metals, the details of the Fermi surface and the magnitude of the matrix elements connecting different points defined on it determine most of their transport properties, which are limited by the electron-phonon coupling and the scattering by ...

Optical signatures of shear collective modes in strongly interacting Fermi liquids
The concept of Fermi liquid lays a solid cornerstone to the understanding of electronic correlations in quantum matter. This ordered many-body state rigorously organizes electrons at zero temperature in progressively higher momentum states, up to the ...

Asymptotic Pomeranchuk instability of Fermi liquids in half-filled Landau levels
We present a theory of spontaneous Fermi surface deformations for half-filled Landau levels (filling factors of the form $$\nu =2 \, n+1/2$$ ν = 2 n + 1 / 2 ).

Electron-positron momentum densities in Y, reconstructed from two-dimensional angular correlation of annihilation radiation spectra, are compared with the theoretical predictions of fully-relativistic augmented plane-wave calculations. Knowledge of the theoretical densities and of the effects on them of certain symmetry selection rules has allowed us ...

Fermi Surface Reconstruction without Symmetry Breaking
We present a sign-problem-free quantum Monte Carlo study of a model that exhibits quantum phase transitions without symmetry breaking and associated changes in the size of the Fermi surface.
