Pseudogap phase of cuprate superconductors confined by Fermi surface topology. [PDF]
Nat Commun, 2017 The properties of cuprate high-temperature superconductors are largely shaped by competing phases whose nature is often a mystery. Chiefly among them is the pseudogap phase, which sets in at a doping p* that is material-dependent.

Emergent Fermi surface in a many-body non-Hermitian fermionic chain [PDF]
, 2019 Fermion accumulation due to asymmetric pumping in a one-dimensional chain is found not only to resemble a Fermi surface in real space, but also to behave like a genuine Fermi surface in its entropy scaling behavior.

Topological order, emergent gauge fields, and Fermi surface reconstruction [PDF]
Reports on progress in physics. Physical Society, 2018 This review describes how topological order associated with the presence of emergent gauge fields can reconstruct Fermi surfaces of metals, even in the absence of translational symmetry breaking.

Quantum chaos on a critical Fermi surface. [PDF]
Proc Natl Acad Sci U S A, 2017 Significance All high-temperature superconductors exhibit a remarkable “strange metal” state above their critical temperatures. A theory of the strange metal is a prerequisite for a deeper understanding of high-temperature superconductivity, but the ...

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 ...

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 ...

Spinon Fermi Surface in a Cluster Mott Insulator Model on a Triangular Lattice and Possible Application to 1T-TaS_{2}. [PDF]
Physical Review Letters, 2018 1T-TaS_{2} is a cluster Mott insulator on the triangular lattice with 13 Ta atoms forming a star of David cluster as the unit cell. We derive a two-dimensional XXZ spin-1/2 model with a four-spin ring exchange term to describe the effective low energy ...

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 ...

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 ...
