Bulk Fermi surface of the Weyl type-II semimetallic candidate NbIrTe 4 [PDF]

, 2016
The electronic structure of WTe${}_{2}$ and of orthorhombic $\ensuremath{\gamma}$-MoTe${}_{2}$ are theoretically claimed to contain pairs of Weyl type-II points associated with linearly touching electron and hole pockets.

ARPES Spectra of the Hubbard model

, 2001
We discuss spectra calculated for the 2D Hubbard model in the intermediate coupling regime with the dynamical cluster approximation, which is a non-perturbative approach.

Spectral weight suppression and Fermi arc-like features with strong holographic lattices

Journal of High Energy Physics, 2019
We investigate holographic fermions in uni-directional striped phases, where the breaking of translational invariance can be generated either spontaneously or explicitly.

Universal entanglement signatures of quantum liquids as a guide to fermionic criticality

New Journal of Physics, 2023
An outstanding challenge involves understanding the many-particle entanglement of liquid states of quantum matter that arise in systems of interacting electrons.

Stability of Fermi Surfaces and K-Theory [PDF]

Phys.Rev.Lett.95:016405,2005, 2005
Nonrelativistic Fermi liquids in d+1 dimensions exhibit generalized Fermi surfaces: (d-p)-dimensional submanifolds in the momentum-frequency space supporting gapless excitations. We show that the universality classes of stable Fermi surfaces are classified by K-theory, with the pattern of stability determined by Bott periodicity.

Diffusion at the surface of topological insulators

New Journal of Physics, 2012
We consider the dc transport properties of topological insulator surface states in the presence of uncorrelated point-like disorder, both in the classical and quantum regimes.

Charge Friedel oscillations in a Mott insulator

, 2010
When a metal undergoes a transition to an insulator it will lose its electronic Fermi surface. Interestingly in some situations a `ghost' Fermi surface of electrically neutral spin carrying fermions may survive into the insulator.

Evolution of the low-temperature Fermi surface of superconducting FeSe1−xSx across a nematic phase transition [PDF]

npj Quantum Materials, 2016
The existence of a nematic phase transition in iron-chalcogenide superconductors poses an intriguing question about its impact on superconductivity.

Covalently‐Bonded Diaphite Nanoplatelet with Engineered Electronic Properties of Diamond

Advanced Functional Materials, EarlyView.
A novel approach to engineering the electronic properties of diamond is reported on the diaphite nanoplatelet consisting of (11¯${{\bar{1}}}$1) planes of diamond nanoplatelet covalently bonded with graphite (0001) planes. The strong sp3/sp2‐hybridized interfacial covalent bonding induces the electron transfer from diamond to graphite, resulting in a ...
