Magnetoresistance from Fermi surface topology [PDF]
Physical review B, 2018 Extremely large nonsaturating magnetoresistance has recently been reported for a large number of both topologically trivial and nontrivial materials. Different mechanisms have been proposed to explain the observed magnetotransport properties, yet without

Nonlinear bosonization of Fermi surfaces: The method of coadjoint orbits
Physical Review Research, 2022 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 ...

Electron hydrodynamics with a polygonal Fermi surface [PDF]
Physical review B, 2019 Recent experiments have observed hints of hydrodynamic electron flow in a number of materials, not all of which have a simple Fermi surface. Motivated by such experiments in $\mathrm{PdCoO}_2$, a quasi-two-dimensional material whose Fermi surface is a ...

Optical signatures of shear collective modes in strongly interacting Fermi liquids
Physical Review Research, 2021 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 ...

Materials Science Forum, 2001 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 ...

Proceedings, 2019 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 ...

Fermi Surface Reconstruction without Symmetry Breaking
Physical Review X, 2020 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.

Asymptotic Pomeranchuk instability of Fermi liquids in half-filled Landau levels
Scientific Reports, 2023 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 ).
