论文摘要
我们表明，一个非热的两个耦合的sachdev-ye-kitaev（SYK）模型可以提供与Hermitian两个耦合SYK模型等效的热力学结构。该模型的能量光谱，基态的纠缠程度和低能量有效作用不受非热性的影响。新型的生物双歧态基础状态表明，两个SYK站点可以通过调整非热性来处于基态，另一个可以处于施瓦茨式激发状态。我们发现自由能独立于非热性的证据。
We show that a non-Hermitian two coupled Sachdev-Ye-Kitaev (SYK) model can provide thermodynamic structure equivalent to Hermitian two coupled SYK model. The energy spectrum, the entanglement degree of the ground states and the low energy effective action of this model are not influenced by the non-Hermiticity. The novel biorthogonal ground states demonstrates that two SYK sites, one of which can be in the ground state and the other in the Schwarzian excited state by tuning the non-Hermiticity. We find evidence that the free energy is independent of the non-Hermiticity.
