On 1D, N=4 supersymmetric SYK-type models. Part II

This paper is an extension of our last 1D, N = 4 supersymmetric SYK paper [1]. In this paper we introduced the complex linear supermultiplet (CLS), which is usefully inequivalent to the chiral supermultiplet. We construct three types of models based on the complex linear supermultiplet containing quartic interactions from modified CLS kinetic term, quartic interactions from 3-pt vertices integrated over the whole super-space, and 2(q - 1)-pt interactions generated via superpotentials respectively. A strong evidence for the inevitability of dynamical bosons for 1D, N = 4 SYK is also presented.

Automated summary

This paper is an extension of our previous research on 1D, N = 4 supersymmetric SYK, where we introduce the complex linear supermultiplet (CLS) as an alternative to the chiral supermultiplet. Three types of models based on the CLS are constructed, including quartic interactions from modified CLS kinetic term, quartic interactions from 3-pt vertices integrated over the whole super-space, and 2(q - 1)-pt interactions generated via superpotentials. Strong evidence for the necessity of dynamical bosons in 1D, N = 4 SYK is also presented.
