Multicritical Fermi Surface Topological Transitions [PDF]
Physical Review Letters, 2019 A wide variety of complex phases in quantum materials are driven by electron-electron interactions, which are enhanced through density of states peaks. A well known example occurs at van Hove singularities where the Fermi surface undergoes a topological transition.

Nonlinear magnetotransport shaped by Fermi surface topology and convexity. [PDF]
Nat Commun, 2019 The nature of Fermi surface defines the physical properties of conductors and many physical phenomena can be traced to its shape. Although the recent discovery of a current-dependent nonlinear magnetoresistance in spin-polarized non-magnetic materials ...

Super-geometric electron focusing on the hexagonal Fermi surface of PdCoO2. [PDF]
Nat Commun, 2019 Geometric electron optics may be implemented in solids when electron transport is ballistic on the length scale of a device. Currently, this is realized mainly in 2D materials characterized by circular Fermi surfaces.

Discovery of segmented Fermi surface induced by Cooper pair momentum [PDF]
Science, 2020 Description Imaging a peculiar Fermi surface Running a current through a superconductor can cause the superconducting gap to close on a section of the Fermi surface. However, observing this segmented Fermi surface directly is tricky. To do so, Zhu et al.

Spinon Fermi Surface Spin Liquid in a Triangular Lattice Antiferromagnet NaYbSe2 [PDF]
Physical Review X, 2020 Triangular lattice of rare-earth ions with interacting effective spin-1/2 local moments is an ideal platform to explore the physics of quantum spin liquids (QSLs) in the presence of strong spin-orbit coupling, crystal electric fields, and geometrical ...

Luttinger sum rules and spin fractionalization in the SU(N) Kondo lattice
Physical Review Research, 2021 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 ...

Fermi surface topology and magnetotransport in semimetallic LuSb. [PDF]
Sci Rep, 2017 Several rare-earth monopnictides were shown to exhibit extreme magnetoresistance and field-induced low-temperature plateau of electrical resistivity. These features are also hallmarks of topological semimetals, thus the family is intensively explored ...
