摘要

摘要我们研究了p波全息超导体中的费米子光谱函数。我们证明了具有最小耦合的矢量模型揭示了具有费米弧的p波谱函数。这应该与之前在张量场存在下证明p波弧的研究形成对比。我们研究了动量相关的阶参数、电导率实部的ω-间隙和费米子谱函数。此外，我们将费米子光谱间隙与全息集合中的阶参数并置。我们证明了耦合常数、温度和化学势对光谱函数的影响。

Fermi arc in p-wave holographic superconductors

Abstract

We have investigated the fermionic spectral function in p-wave holographic superconductors. We show that the vector model with minimal coupling reveals a p-wave spectral function with Fermi arc. This should be contrasted with the previous investigation where p-wave arc was demonstrated in the presence of a tensor field. We study the momentum dependent order parameter, the ω-gap in the real part of the conductivity and the fermion spectral function. In addition, we juxtapose the fermionic spectral gap with the order parameter in the holographic set. We demonstrate the impact of coupling constants, temperature and chemical potential on the spectral function.

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
