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.

Multifold Fermions and Fermi Arcs Boosted Catalysis in Nanoporous Electride 12CaO·7Al2O3

Advanced Science, 2023
Topological materials have been recently regarded as ideal catalysts for heterogeneous reactions due to their surface metallic states and high carrier mobility.

Perturbative non-Fermi liquids from dimensional regularization

, 2013
We devise a dimensional regularization scheme for quantum field theories with Fermi surface to study scaling behaviour of non-Fermi liquid states in a controlled approximation.

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.

Berry Curvature, Triangle Anomalies, and the Chiral Magnetic Effect in Fermi Liquids

, 2012
In a three-dimensional Fermi liquid, quasiparticles near the Fermi surface may possess a Berry curvature. We show that if the Berry curvature has a nonvanishing flux through the Fermi surface, the particle number associated with this Fermi surface has a ...

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.

Deformation of anisotropic Fermi surfaces due to electron-electron interactions

, 2006
We analyze the deformations of the Fermi surface induced by electron-electron interactions in anisotropic two dimensional systems. We use perturbation theory to treat, on the same footing, the regular and singular regions of the Fermi surface.

The change of Fermi surface topology in Bi2Sr2CaCu2O8 with doping [PDF]

, 2005
We report the observation of a change in Fermi surface topology of Bi2Sr2CaCu2O8 with doping. By collecting high statistics ARPES data from moderately and highly overdoped samples and dividing the data by the Fermi function, we answer a long standing ...
