摘要：

We study the ground-state structural properties of a hydrogen molecule in superstrong magnetic fields (B approximate to 10(12) G) using quantum Monte Carlo (fixed-phase and variational) approaches. We determine that the ground state (spin-triplet) belongs to the sector of total (z-component) angular-momentum M = -1 ((3) Pi(0)), meaning that paramagnetic contributions to the total energy cannot be neglected. This non-time-reversal invariant ground state has a strong interatomic interaction, suggesting that a hydrogen gas under the same physical conditions has a tendency to form strong bonded molecules.
