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.

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.

Study of structural and electronic properties of intercalated CrTiS2 compound by density functional theory

open access: yesEurasian Journal of Physics and Functional Materials, 2021
In the present paper, we report the structural optimization of intercalated CrTiS 2 compound by using Density Functional Theory (DFT) with Generalized Gradient Approximation (GGA) through Quantum ESPRESSO code.

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 ...

Topological order, emergent gauge fields, and Fermi surface reconstruction [PDF]

open access: yesReports 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.

Spinon Fermi Surface in a Cluster Mott Insulator Model on a Triangular Lattice and Possible Application to 1T-TaS_{2}. [PDF]

open access: yesPhysical 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 ...

Emergent Fermi surface in a many-body non-Hermitian fermionic chain [PDF]

open access: yes, 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.
