我们提出了 AdS4 的全息理论,其零温度基态形成晶体结构,自发打破平移对称性。该晶体由背景磁场感应产生,但不需要化学势。这种晶格源于体中存在的“t Hooft-Polyakov”单极孤子,这些孤子凝结成一个被称为单极壁的经典物体。在红外线中,磁场被屏蔽并且出现了 SU(2) 全局对称性。
We present a holographic theory in AdS4 whose zero temperature ground state develops a crystal structure, spontaneously breaking translational symmetry. The crystal is induced by a background magnetic field, but requires no chemical potential. This lattice arises from the existence of ’t Hooft-Polyakov monopole solitons in the bulk which condense to form a classical object known as a monopole wall. In the infra-red, the magnetic field is screened and there is an emergent SU(2) global symmetry.
