چکیده
|
The syk model consists of n ≫ 1 fermions in 0 + 1 dimensions with a random, all-to-all quartic interaction. recently, kitaev has found that the syk model is maximally chaotic and has proposed it as a model of holography. we solve the schwingerdyson equation and compute the spectrum of two-particle states in syk, finding both a continuous and discrete tower. the four-point function is expressed as a sum over the spectrum. the sum over the discrete tower is evaluated.
