R. D. Benguria, R. Brummelhuis, P. Duclos, S. Perez-Oyarzun

摘要:

本文研究了在强均匀磁场中氢分子离子$H^+_2$的运动。在这种情况下,有效哈密顿量几乎是一维的,其势能看起来像两个狄拉克δ函数之和。这个模型是可解的,但对于相应的磁场强度,它与我们的精确哈密顿量还不够接近。然而,我们表明,正确的值的平衡距离,以及离子的基态的结合能,可以得到当纳入微扰校正到二阶。最后,我们表明,$ He_2^{3+}$存在足够大的磁场。

英文摘要:

We consider the hydrogen molecular ion $H^+_2$ in the presence of a strong homogeneous magnetic field. In this regime, the effective Hamiltonian is almost one dimensional with a potential energy which looks like a sum of two Dirac delta functions. This model is solvable, but not close enough to our exact Hamiltonian for relevant strenght of the magnnetic field. However we show that the correct values of the equilibrium distance as well as the binding energy of the ground state of the ion, can be obtained when incorporating perturbative corrections up to second order. Finally, we show that $ He_2^{3+}$ exists for sufficiently large magnetic fields.
