我们研究了著名的Sachdev-Ye-Kitaev(SYK)模型的复杂版本中非高斯平均数对随机耦合的影响。 使用类Polchinski方程和随机张量高斯普适性,我们证明了这种非高斯平均效应会导致N上领先的偶合器高斯分布方差的修正。然后,我们得出了有效形式。 对所有订单采取行动。 对于上述的复杂SYK模型和D. Gross和V. Rosenhaus [J. ...

量子混沌是Sachdev-Ye-Kitaev(SYK)模型的显着特征之一,N马约拉纳费米子在0 + 1维具有无限范围的两体相互作用,作为全息玩具模型吸引了很多兴趣。 。 在这里,我们通过分析和数值显示,具有附加的单体无限范围随机相互作用的广义SYK模型(与红外相关的扰动)仍然是量子混沌的,并且对于固定的扰动值仍保留其大部分全息特征 ...
The Sachdev-Ye-Kitaev (SYK) model incorporates rich physics, ranging from exotic non-Fermi liquid states without quasiparticle excitations, to holographic duality and quantum chaos. However, its experimental realization remains a daunting challenge due to various unnatural ingredients of the SYK Hamiltonia...
We derive holographic superconductivity in form of a gravity theory with emergent space-time from a quantum many-body Hamiltonian—the Yukawa Sachdev-Ye-Kitaev model—where the Eliashberg formalism is exact. Exploiting the power of holography, we then determine the dynamic pairing susceptibility of ...

30 Oct 2019 · Yingfei Gu, Alexei Kitaev, Subir Sachdev, Grigory Tarnopolsky · Edit social preview We describe numerous properties of the Sachdev-Ye-Kitaev model for complex fermions with N≫1 flavors and a global U(1) charge. We provide a general definition of the charge in the (G,...
The 0+1-d Sachdev-Ye-Kitaev (SYK) fermionic model attracts nowadays a wide spread interest of the Condensed Matter community, as a benchmark toy model for strong electron correlation and non Fermi Liquid behavior. It is exactly solvable in the infrared limit and reproduces the linear dependence...
