报告题目:SYK-like models, Higher-spins and Chaos

报告人:彭程博士(布朗大学)

报告地点:天津大学新校区理学院32教256

报告摘要I will discuss an SYK-like model in 1+1 dimension. Large higher-spin symmetries emerge in special limits of this model, where the model stops being chaotic. Our analysis suggests that this model might be considered as a toy model to study some appropriate tensionless limit of String theory.
