Baby universe operators in the ETH matrix model of double-scaled SYK
Abstract We consider the baby universe operator B a $$ {\mathcal{B}}_a $$ in the double-scaled SYK (DSSYK) model, which creates a baby universe of size a. We find that B a $$ {\mathcal{B}}_a $$ is written in terms of the transfer matrix T, and vice versa. In particular, the identity operator on the...
