Fermi surface of a trapped dipolar Fermi gas [PDF]
Physical 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]
Physical 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
Journal 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 ...

Multicritical Fermi Surface Topological Transitions. [PDF]
Physical Review Letters, 2018 A wide variety of complex phases in quantum materials are driven by electron-electron interactions, which are enhanced through density of states peaks. A well-known example occurs at van Hove singularities where the Fermi surface undergoes a topological ...

Generalized fermi derivative on the hypersurfaces
MANAS: Journal of Engineering, 2022 In this paper, generalized Fermi derivative, generalized Fermi parallelism, and generalized non-rotating frame concepts are given along any curve on any hypersurface in Eⁿ⁺¹ Euclidean space.

Comments on holographic Fermi surfaces [PDF]
Journal 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.

Infinite critical boson non-Fermi liquid
npj 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

Topological semimetals carrying arbitrary Hopf numbers: Fermi surface topologies of a Hopf link, Solomon's knot, trefoil knot, and other linked nodal varieties [PDF]
, 2017 We propose a type of Hopf semimetal indexed by a pair of numbers $(p,q)$, where the Hopf number is given by $pq$. The Fermi surface is given by a preimage of the Hopf map, which consists of loops nontrivially linked for a nonzero Hopf number.

Zeeman-induced gapless superconductivity with a partial Fermi surface [PDF]
, 2018 We show that an in-plane magnetic field can drive two-dimensional spin-orbit-coupled systems under superconducting proximity effect into a gapless phase where parts of the normal state Fermi surface are gapped, and the ungapped parts are reconstructed ...
