Replica Symmetry Breaking and Phase Transitions in a PT Symmetric Sachdev-Ye-Kitaev Model
Antonio M. García-García, Yiyang Jia, Dario Rosa +1
We show that the low temperature phase of a conjugate pair of uncoupled, quantum chaotic, nonhermitian systems such as the Sachdev-Ye-Kitaev (SYK) model or the Ginibre ensemble of…
Universal Thermodynamics in the Kitaev Fractional Liquid
Han Li, Dai-Wei Qu, Hao-Kai Zhang +4
In the Kitaev honeycomb model, the quantum spin fractionalizes into itinerant Majorana and gauge flux spontaneously upon cooling, leading to rich experimental ramifications at fini…
Chaos on the hypercube
Yiyang Jia, Jacobus J. M. Verbaarschot
We analyze the spectral properties of a -dimensional HyperCubic (HC) lattice model originally introduced by Parisi. The U(1) gauge links of this model give rise to a magnetic fl…
Spectral Fluctuations in the Sachdev-Ye-Kitaev Model
Yiyang Jia, Jacobus J. M. Verbaarschot
We present a detailed quantitative analysis of spectral correlations in the Sachdev-Ye-Kitaev (SYK) model. We find that the deviations from universal Random Matrix Theory (RMT) beh…
Large expansion of the moments and free energy of Sachdev-Ye-Kitaev model, and the enumeration of intersection graphs
Yiyang Jia, Jacobus J. M. Verbaarschot
In this paper we explain the relation between the free energy of the SYK model for Majorana fermions with a random -body interaction and the moments of its spectral density.…
