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...
متن کاملThermal Transport in the Kitaev Model.
In conventional insulating magnets, heat is carried by magnons and phonons. In contrast, when the magnets harbor a quantum spin liquid state, emergent quasiparticles from the fractionalization of quantum spins can carry heat. Here, we investigate unconventional thermal transport yielded by such exotic carriers, in both longitudinal and transverse components, for the Kitaev model, whose ground s...
متن کاملQuadratic exponential vectors
We give a necessary and sufficient condition for the existence of a quadratic exponential vector with test function in L2(Rd) ∩ L∞(Rd). We prove the linear independence and totality, in the quadratic Fock space, of these vectors. Using a technique different from the one used in [2], we also extend, to a more general class of test functions, the explicit form of the scalar product between two su...
متن کاملSachdev 1
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...
