The Holographic QCD Axion in Five Dimensions
Csaba Csáki, Eric Kuflik, Wei Xue +1
We present a holographic construction of the QCD axion based on a warped 5D model. A key ingredient of our setup is the introduction of a bulk scalar field , which is holograph…
Angle and Axial Anomaly in Holographic QCD
Csaba Csáki, Eric Kuflik, Wei Xue +1
We present a bottom-up holographic description of the QCD -vacuum and the anomaly in five dimensions. The multi-branched -vacuum structure emerges geometrically fr…
Axion strings from string axions
James M. Cline, Christos Litos, Wei Xue
A favored scenario for axions to be dark matter is for them to form a cosmic string network that subsequently decays, allowing for a tight link between the axion mass and relic abu…
Stability of Superconducting Strings
Keisuke Harigaya, Xuce Niu, Wei Xue +1
We investigate the stability of superconducting strings as bound states of strings and fermion zero modes at both the classical and quantum levels. The dynamics of these supercondu…
