普适电导率与中心荷
Universal conductivity and central charges
摘要：
讨论了一类d>1+1维临界模型，其电导率和电荷磁化率由中心荷以普适的方式固定。我们评论的电导率可能的界限，建议由全息对偶。
英文摘要：
We discuss a class of critical models in d>1+1 dimensions whose electrical conductivity and charge susceptibility are fixed by the central charge in a universal manner. We comment on possible bounds on conductivity, as suggested by holographic duality.
