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 ...

Quasi-2D Fermi surface in the anomalous superconductor UTe2 [PDF]

Nature Communications, 2023
The 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 ...

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

Extent of Fermi-surface reconstruction in the high-temperature superconductor HgBa₂CuO_4+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.

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 ...

Fermi surface of yttrium [PDF]

Materials Science Forum, 2002
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 ...

Pressure-enhanced f-electron orbital weighting in UTe2 mapped by quantum interferometry [PDF]

Communications Physics
The phase landscape of UTe2 features a remarkable diversity of superconducting phases under applied pressure and magnetic field. Recent quantum oscillation studies at ambient pressure have revealed the quasi-2D Fermi surface of this material.

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.
