Description
We present an approach to solve two-fermion problems using the Quantic Tensor Train (QTT) method. The QTT format allows us to represent high-resolution wavefunctions and operators with a memory cost that only scales logarithmically with the number of grid points. We demonstrate our method by showing our calculations on the ground state of a hydrogen molecule ($H_2$) and its quantum dynamics under an external electric field. Our results show that the QTT-based solver achieves controlled accuracy and successfully captures particle correlation effects.
