Fermi surface tomography [PDF]
Nature Communications, 2022 The Fermi surface is related to the energy distribution of electrons in a solid, and governs physical properties of metals and semiconductors. A new type of angle-resolved photoemission spectroscopy, probing the Fermi surface and combining short ...

Extent of Fermi-surface reconstruction in the high-temperature superconductor HgBa2CuO4+δ. [PDF]
Proc Natl Acad Sci U S A, 2020 High magnetic fields have revealed a surprisingly small Fermi-surface in underdoped cuprates, possibly resulting from Fermi-surface reconstruction due to an order parameter that breaks translational symmetry of the crystal lattice.

Anomalous Chiral Fermi Surface
Physical Review Letters, 2012 We provide a geometrical argument for the emergence of a Wess-Zumino-Witten (WZW) term for a Fermi surface threaded by a Berry curvature. In the presence of external fields, the gauged WZW term yields a chiral (triangle) anomaly for the fermionic current

Creating Majorana modes from segmented Fermi surface [PDF]
Nature Communications, 2021 Despite striking progress in promoting Majorana physics to topological quantum computation, there are many disadvantages in existing material platforms. Here, Papaj and Fu propose a new two-dimensional system for realization of Majorana physics based on ...

Quasi-2D Fermi surface in the anomalous superconductor UTe2 [PDF]
Nature CommunicationsThe heavy fermion paramagnet UTe2 exhibits numerous characteristics of spin-triplet superconductivity. Efforts to understand the microscopic details of this exotic superconductivity have been impeded by uncertainty regarding the underlying electronic ...

Deformation of the Fermi surface of a spinless two-dimensional electron gas in presence of an anisotropic Coulomb interaction potential [PDF]
Scientific Reports, 2021 We consider the stability of the circular Fermi surface of a two-dimensional electron gas system against an elliptical deformation induced by an anisotropic Coulomb interaction potential.

Fermi Surface, Surface States, and Surface Reconstruction in Sr2RuO4 [PDF]
, 2000 The electronic structure of Sr2RuO4 is investigated by high angular resolution ARPES at several incident photon energies. We address the controversial issues of the Fermi surface (FS) topology and of the van Hove singularity at the M point, showing that ...

Super-geometric electron focusing on the hexagonal Fermi surface of PdCoO2 [PDF]
Nature Communications, 2019 Ballistic electron beams in clean metals can be focused by passing currents through well designed contraptions, which is mostly done in isotropic materials described by a circular Fermi surface.

Electron–hole doping asymmetry of Fermi surface reconstructed in a simple Mott insulator [PDF]
Nature Communications, 2016 Electron or hole doping in a Mott insulator leads to superconductivity, with the mechanism obscured by multi-orbital Fermi surface reconstructions. Here, Kawasugi et al.
