我们考虑 Pekar-Tomasevich 近似中的双极子,并解决基态是否球对称的问题。到目前为止,数值分析还没有完全解决这个问题。我们的贡献是严格证明,在电子-电子库仑斥力较小的情况下,基态仍保持球形。
We consider the bipolaron in the Pekar–Tomasevich approximation and address the question whether the ground state is spherically symmetric or not. Numerical analysis has, so far, not completely settled the question. Our contribution is to prove rigorously that the ground state remains spherical for small values of the electron-electron Coulomb repulsion.
