Using the de Haas-van Alphen effect to map out the closed three-dimensional Fermi surface of natural graphite [PDF]

open access: yes, 2011
The Fermi surface of graphite has been mapped out using de Haas van Alphen (dHvA) measurements at low temperature with in-situ rotation. For tilt angles $\theta>60^{\circ}$ between the magnetic field and the c-axis, the majority electron and hole dHvA periods no longer follow the $\cos(\theta)$ behavior demonstrating that graphite has a 3 dimensional ...

Charge inhomogeneity coexisting with large Fermi surfaces [PDF]

open access: yes, 2007
We discuss how stripes in cuprates can be compatible with a Fermi-liquid-like Fermi surface and, at the same time, they give rise to a one-dimensional-like pseudo Fermi surface in the momentum distribution function.

Butterfly magnetoresistance, quasi-2D Dirac Fermi surface and topological phase transition in ZrSiS. [PDF]

open access: yesSci Adv, 2016
An unusual angle-dependent topological phase transition and butterfly magnetoresistance were found in the Dirac semimetal ZrSiS. Magnetoresistance (MR), the change of a material’s electrical resistance in response to an applied magnetic field, is a ...

Single reconstructed Fermi surface pocket in an underdoped single-layer cuprate superconductor. [PDF]

open access: yesNat Commun, 2016
The observation of a reconstructed Fermi surface via quantum oscillations in hole-doped cuprates opened a path towards identifying broken symmetry states in the pseudogap regime.

Estimating the quasi-Fermi level of holes at the surface of semiconductor photoanodes using outer-sphere redox couples [PDF]

open access: yesNature Communications
Semiconductor electrodes can catalyze photo-induced redox reactions with light illumination. Photoexcitation produces excited carriers that subsequently transfer to the front and back contacts as determined by the bulk and surface properties of the ...

Electron–hole doping asymmetry of Fermi surface reconstructed in a simple Mott insulator [PDF]

open access: yesNature 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.

Discovery of segmented Fermi surface induced by Cooper pair momentum [PDF]

open access: yesScience, 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.

Luttinger sum rules and spin fractionalization in the SU(N) Kondo lattice

open access: yesPhysical 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 ...
