The Sachdev-Ye-Kitaev quantum mechanics model, black holes, and random matricesDouglas StanfordMember, School of Natural SciencesOctober 26, 2016 Kitaev is also known for contributions to research on a model relevant to researchers of the AdS/CFT correspondence started by Subir Sachdev and Jinwu Ye; this model is known as the Sachdev-Ye-Kitaev (SYK) model. In this work, we consider a generalization of the SYK model that contains two SYK models with a different number of Majorana modes coupled by quadratic terms. Recently, Kitaev has found that the SYK model is maximally chaotic and has proposed it as a model of holography. We argue that the structure of the soft-mode Schwarzian action is qualitatively different in replica-diagonal vs .

The Sachdev-Ye-Kitaev (SYK) model describes Majorana fermions with random interaction, which displays many interesting properties such as non-Fermi liquid behavior, quantum chaos, emergent conformal symmetry and holographic duality. Thank Subir for introducing me the interesting Sachdev-Ye-Kitaev model that this thesis is based on, I enjoyed a lot when studying and exploring. In condensed matter physics it was proposed as a model for a spin liquid by Sachdev and Ye, but the model only really took off a few years ago after Kitaev introduced it as a model for a black hole.
