斯莱特行列式的矩阵乘积态表示和组态相互作用态

Matrix Product State representation for Slater Determinants and Configuration Interaction States

Pietro Silvi, Davide Rossini, Rosario Fazio, Giuseppe E. Santoro, Vittorio Giovannetti

摘要:

斯莱特行列式是满量子费米子轨道的乘积态。当它们被表示在一个先验选择的位形空间基上时,它们的纠缠是受约束和控制的。这表明斯莱特行列式作为有限相关态的精确表示是可能的。本文分析了这个问题,并给出了Slater行列式态的一个精确的矩阵积表示。我们还认为可能有意义的扩展,嵌入更复杂的配置交互状态的描述。

英文摘要:

Slater determinants are product states of filled quantum fermionic orbitals. When they are expressed in a configuration space basis chosen a priori, their entanglement is bound and controlled. This suggests that an exact representation of Slater determinants as finitely-correlated states is possible. In this paper we analyze this issue and provide an exact Matrix Product representation for Slater determinant states. We also argue possible meaningful extensions that embed more complex configuration interaction states into the description.
