Abstract: The Sachdev-Ye-Kitaev(SYK) model is a microscopic realization of the duality between a gravitational field and a gauge field. After a briefly review of SYK model and JT gravity, I will present our recent studies. We investigate the diffusive property of an extended SYK model with complex fermions. Based on an SYK-like tensor model, we find a superconducting gap ratio. Besides, we propose a Non-Hermitian quantum system generated from two coupled SYK models. Then, we investigate TTbar deformation on this model and the wormhole-black hole picture.
