ASEP/DSSYK duality and strange correlator
Kazumi Okuyama
We show that the moment of the transfer matrix of the double scaled SYK model is written as an overlap between the stationary state of ASEP (asymmetric simple exclusion process) an…
Holographic tensor network for double-scaled SYK
Kazumi Okuyama
We construct a holographic tensor network for the double-scaled SYK model (DSSYK). The moment of the transfer matrix of DSSYK can be mapped to the matrix product state (MPS) of a s…
Non-perturbative corrections in the semi-classical limit of double-scaled SYK
Kazumi Okuyama
We study the disk partition function of double-scaled SYK model (DSSYK) in the small limit, where is the coupling of DSSYK. We find that the partition function rece…
Baby universe operators in the ETH matrix model of double-scaled SYK
Kazumi Okuyama
We consider the baby universe operator in the double-scaled SYK (DSSYK) model, which creates a baby universe of size . We find that is written in…
More on doubled Hilbert space in double-scaled SYK
Kazumi Okuyama
We continue our study of the doubled Hilbert space formalism of double-scaled SYK model initiated in [arXiv:2401.07403]. We show that the 1-particle Hilbert space introduced by Lin…
Doubled Hilbert space in double-scaled SYK
Kazumi Okuyama
We consider matter correlators in the double-scaled SYK (DSSYK) model. It turns out that matter correlators have a simple expression in terms of the doubled Hilbert space $\mathcal…
Matter correlators through a wormhole in double-scaled SYK
Kazumi Okuyama
We compute the two-point function of matter operators in the double-scaled SYK (DSSYK) model, where the two matter operators are inserted at each end of the cylindrical wormhole. W…
Solvable limit of ETH matrix model for double-scaled SYK
Kazumi Okuyama, Takao Suyama
We study the two-matrix model for double-scaled SYK model, called ETH matrix model introduced by Jafferis et al [arXiv:2209.02131]. If we set the parameters of this model…
