报告摘要:
Holographic axion models are a class of bottom-up holographic systems characterized by the presence of a set of shift-symmetric scalar bulk fields, whose profiles are taken to be linear in the spatial coordinates. These systems implement the breaking of translational symmetry in the dual field theory while retaining the homogeneity of the background geometry, allowing for controllable and efficient computations. Their applications are vast, demonstrating the remarkable versatility of the framework. In this talk, I will show how these simple models capture some key features of solid systems and provide novel insights into non-linear elastic behavior, mechanical instabilities as well as complexity in solids through the lens of black hole physics.
