大N矩阵量子力学中的多瞬子

Multi-instantons in large N Matrix Quantum Mechanics

Marcos Marino, Pavel Putrov

摘要:

计算了大$N$矩阵量子力学中基态能量的多瞬子修正。我们发现,它们可以得到,通过一个非微扰差分方程,从多瞬子系列在传统的量子力学,确定的精确WKB方法。我们测试我们的结果,通过验证的一个瞬子校正控制的四次势和$c=1$字符串中的$1/N$扩展的大的顺序行为。

英文摘要:

We calculate the multi-instanton corrections to the ground state energy in large $N$ Matrix Quantum Mechanics. We find that they can be obtained, through a non-perturbative difference equation, from the multi-instanton series in conventional Quantum Mechanics, as determined by the exact WKB method. We test our results by verifying that the one-instanton correction controls the large order behavior of the $1/N$ expansion in the quartic potential and in the $c=1$ string.
