Theory of the quasiparticle excitation in high T cuprates: quasiparticle charge and nodal-antinodal dichotomy
Fan Yang, Tao Li
A variational theory is proposed for the quasiparticle excitation in high T cuprates. The theory goes beyond the usual Gutzwiller projected mean field state description by in…
Variational study of the neutron resonance mode in the cuprate superconductors
Tao Li, Fan Yang
A Gutzwiller-type variational wave function is proposed for the neutron resonance mode in the cuprate superconductors. An efficient re-weighting technique is devised to perform var…
Recommendation model based on opinion diffusion
Yi-Cheng Zhang, Matus Medo, Jie Ren +3
Information overload in the modern society calls for highly efficient recommendation algorithms. In this letter we present a novel diffusion based recommendation model, with users'…
On the Origin of the Tunneling Asymmetry in the Cuprate Superconductors: a variational perspective
Hong-Yu Yang, Fan Yang, Yong-Jin Jiang +1
Through variational Monte Carlo calculation on Gutzwiller projected wave functions, we study the quasiparticle(qp) weight for adding and removing an electron from a high temperatur…
Why a local moment induces an antiferromagnetic ordering: An RVB picture
Tao Li, Qiang-Hua Wang, Zheng-Yu Weng +2
Based on a Gutzwiller projected BCS wavefunction, it is shown that a local S=1/2 moment is present around a vacancy site (zinc impurity) in a form of staggered magnetic moments, wh…
On the Origin of the Tunneling Asymmetry in the Cuprate Superconductors
Tao Li, Fan Yang, Yong-Jin Jiang
We argue the coherent part of the spectral weight always contribute symmetrically to the STM spectrum at sufficiently low energy and the tunneling asymmetry is a manifestation of t…
