Comments on the Sachdev-Ye-Kitaev model

We study a quantum mechanical model proposed by Sachdev, Ye and Kitaev. The model consists of N Majorana fermions with random interactions of a few fermions at a time. It it tractable in the large N limit, where the classical variable is a bilocal fermion bilinear. The model becomes strongly interacting at low energies where it develops an emergent conformal symmetry. We study two and four poin...

Economists have been puzzled by the recent trends in real wage and productivity growth. While productivity has risen steadily, the popular press has lamented that real wages have failed to keep pace. Some argue that the inclusion of benefits explains the disparity. Others suggest that labor has lost much of its bargaining power with the firm, as evidenced by a decline in unionization rates, and...

Kitaev And

Recently, Kitaev [Ki2] introduced partially ordered generalized patterns (POGPs) in the symmetric group, which further generalize the generalized permutation patterns introduced by Babson and Steingŕımsson [BS]. A POGP p is a GP some of whose letters are incomparable. In this paper, we study the generating functions (g.f.) for the number of k-ary words avoiding some POGPs. We give analogues, ex...
