We show that the five-dimensional Maxwell theory with the Chern-Simons term is tachyonic in the presence of a constant electric field. When coupled to gravity, a sufficiently large Chern-Simons coupling causes instability of the Reissner-Nordstrom black holes in anti-de Sitter space. The instability happens only at non-vanishing momenta, suggesting a spatially modulated phase in the holographically dual quantum field theory in 3+1 dimensions, with spontaneous current generation in a helical configuration. The three-charge extremal black hole in the type IIB superstring theory on AdS_5 x S^5 barely satisfies the stability condition.
Spatially Modulated Instabilities of Geometries with Hyperscaling Violation
我们进行了研究的红外AdS 2 x R2区域的解决方案，爱因斯坦-麦克斯韦-狄龙系统表现出超标度违反和Lifshitz标度的中间制度的可能的不稳定性。专注于解决方案，磁荷，我们探测系统的空间调制波动的响应，并确定区域的参数空间中的红外AdS 2的几何形状是不稳定的扰动。不稳定性存在的条件转化为对规范动力学函数和标量势结构的限制。反过来，这些可以导致对动力学临界指数z和超标度破坏θ的量的限制。因此，我们的分析提供了进一步的证据的概念，真正的基态的“标度”的解决方案与超标度破坏可能是空间调制相位。
