双电子波函数是键维数为3的矩阵乘积态

Two-electron wavefunctions are matrix product states with bond dimension Three

Gero Friesecke, Benedikt R. Graswald

摘要:

我们证明了标题中的陈述,对于一个合适的(依赖于波函数的)底层轨道的选择,并表明三是最优的。因此,对于双电子系统,键维为3的QC-DMRG方法结合费米子模式优化准确地恢复了FCI能量。

英文摘要:

We prove the statement in the title, for a suitable (wavefunction-dependent) choice of the underlying orbitals, and show that Three is optimal. Thus for two-electron systems, the QC-DMRG method with bond dimension Three combined with fermionic mode optimization exactly recovers the FCI energy.
