Fermi surface of a trapped dipolar Fermi gas [PDF]

open access: yesPhysical Review A, 2009
Under the framework of the semiclassical theory, we investigate the equilibrium-state properties of a spin polarized dipolar Fermi gas through full numerical calculation. We show that the Fermi surfaces in both real and momentum spaces are stretched along the attractive direction of dipolar interaction.

Remnant Fermi Surfaces in Photoemission [PDF]

open access: yesPhysical Review Letters, 2000
Recent experiments have introduced a new concept for analyzing the photoemission spectra of correlated electrons -- the remnant Fermi surface (rFs), which can be measured even in systems which lack a conventional Fermi surface. Here, we analyze the rFs in a number of interacting electron models, and find that the results fall into two classes.

Isolated zeros destroy Fermi surface in holographic models with a lattice

open access: yesJournal of High Energy Physics, 2020
We study the fermionic spectral density in a strongly correlated quantum system described by a gravity dual. In the presence of periodically modulated chemical potential, which models the effect of the ionic lattice, we explore the shapes of the ...

Infinite critical boson non-Fermi liquid

open access: yesnpj Quantum Materials, 2023
We study a distinct type of non-Fermi liquid where there exists an infinite number of critical bosonic modes instead of finite number of bosonic modes for the conventional ones. We consider itinerant magnets with both conduction electrons and fluctuating

Comments on holographic Fermi surfaces [PDF]

open access: yesJournal of High Energy Physics, 2009
Recently, a mechanism for the development of a fermi surface in a holographic model of large N QCD with a baryon chemical potential was proposed. We examine similar constructions to determine when this mechanism persists. We find a class of models in which it does.

On the relationship between charge ordering and the Fermi arcs observed in underdoped high superconductors

open access: yesNew Journal of Physics, 2014
We address the origin of the recently discovered close correspondence between the charge ordering wave vectors and the momentum-space separation between the tips of the Fermi arcs seen in angle-resolved photoemission measurements in underdoped high ...

Pressure-induced Anderson-Mott transition in elemental tellurium

open access: yesCommunications Materials, 2021
Elemental tellurium is a natural p-type semiconductor with a chiral structure and spin-polarized Fermi surface. Here, the authors show that the pressure-induced topological change of the Fermi surface at 17 kbar triggers an Anderson-Mott insulator-to ...

Fermi-Surface Reconstruction in the Periodic Anderson Model [PDF]

open access: yes, 2008
We study ground state properties of periodic Anderson model in a two-dimensional square lattice with variational Monte Carlo method. It is shown that there are two different types of quantum phase transition: a conventional antiferromagnetic transition ...
