Low-energy Spectra of the t-J-Type Models Studied by Variational Approach
Chung-Pin Chou, T. K. Lee, Chang-Ming Ho
We discuss recent progress of understanding the phenomena observed in high Tc cuprates by studying the d-wave resonating-valence-bond (d-RVB) based trial wave functions for the 2-d…
Spectral Weights, d-wave Pairing Amplitudes, and Particle-hole Tunneling Asymmetry of a Strongly Correlated Superconductor
Chung-Pin Chou, T. K. Lee, Chang-Ming Ho
The spectral weights (SW's) for adding and removing an electron of the Gutzwiller projected d-wave superconducting (SC) state of the t-J-type models are studied numerically on fini…
Low-energy spectra in the t-J type models at light doping
Wei-Cheng Lee, T. K. Lee, Chang-Ming Ho +1
Based on a variational approach, we propose that there are two kinds of low energy states in the t-J type models at low doping. In a quasi-particle state an unpaired spin bound to…
Theory for Slightly Doped Antiferromagnetic Mott Insulators
T. K. Lee, Chang-Ming Ho, Naoto Nagaosa +1
Trial wavefunctions, constructed explicitly from the unique 2-dimensional Mott insulating state with antiferromagnetic order, are proposed to describe the low-energy states of a Mo…
Nature of Spin Excitations in Two-dimensional Mott Insulators: Undoped Cuprates and Other Materials
Chang-Ming Ho, V. N. Muthukumar, Masao Ogata +1
We investigate the excitation spectrum of a two-dimensional resonating valence bond (RVB) state. Treating the -flux phase with antiferromagnetic correlations as a variational g…
