强关联金属的Hall数

The Hall Number of Strongly Correlated Metals

Assa Auerbach

摘要:

导出了金属霍尔数随温度变化的精确公式。它适用于具有任意势和相互作用的非相对论费米子或玻色子。这个DC传输系数被证明(显着)只依赖于平衡的电导率,这是更服从于数值算法比电导率。通过计算格点玻色子Mott相附近的Hall符号,证明了它在强关联相中的应用。

英文摘要:

An exact formula for the temperature dependent Hall number of metals is derived. It is valid for non-relativistic fermions or bosons, with arbitrary potential and interaction. This DC transport coefficient is proven to (remarkably) depend solely on equilibrium susceptibilities, which are more amenable to numerical algorithms than the conductivity. An application to strongly correlated phases is demonstrated by calculating the Hall sign in the vicinity of Mott phases of lattice bosons.
