论文摘要
Four-dimensional $\mathcal{N}=4$ supersymmetric Yang-Mills theory, at a point on the Coulomb branch where $SU(N)$ gauge symmetry is spontaneously broken to $SU(N-1)\times U(1)$, admits BPS solitons describing a spherical shell of electric and/or magnetic charges enclosing a region of unbroken gauge symmetry.这些孤子已被提出为尺度理论模型，用于渐近平坦的极端黑洞的某些特征。在带有大hooft耦合的“ T Hooft大$ n $限制”中，这些孤子在$ ads_5 \ times s^5 $ type iib supergravity的解决方案中对某些探针D3-branes的全息偶性是双重的。通过研究这些D3晶体的线性化扰动，我们表明孤子支持具有各种频率的准模式，这些模式与渐近平坦的极端黑色孔具有定性和定量特征。
Four-dimensional $\mathcal{N}=4$ supersymmetric Yang-Mills theory, at a point on the Coulomb branch where $SU(N)$ gauge symmetry is spontaneously broken to $SU(N-1)\times U(1)$, admits BPS solitons describing a spherical shell of electric and/or magnetic charges enclosing a region of unbroken gauge symmetry. These solitons have been proposed as gauge theory models for certain features of asymptotically flat extremal black holes. In the 't Hooft large $N$ limit with large 't Hooft coupling, these solitons are holographically dual to certain probe D3-branes in the $AdS_5 \times S^5$ solution of type IIB supergravity. By studying linearised perturbations of these D3-branes, we show that the solitons support quasinormal modes with a spectrum of frequencies sharing both qualitative and quantitative features with asymptotically flat extremal black holes.
