Diagrammatic proof of the large N melonic dominance in the SYK model
Letters in Mathematical Physics(2019)
摘要
A crucial result on the celebrated Sachdev–Ye–Kitaev model is that its large N limit is dominated by melonic graphs. In this letter, we offer a rigorous, diagrammatic proof of that result by direct, combinatorial analysis of its Feynman graphs.
