Quantum fluctuations of charge order induce phonon softening in a superconducting cuprate
H. Y. Huang, A. Singh, C. Y. Mou +13
Quantum phase transitions play an important role in shaping the phase diagram of high-temperature cuprate superconductors. These cuprates possess intertwined orders which interact…
Formation and local symmetry of Holstein polaron in t-J model
Han Ma, T. K. Lee, Yan Chen
The formation and local symmetry of spin-lattice polaron has been investigated semiclassically in the planar Holstein t-J-like models within the exact diagonalization method. Due t…
Comment on "High-Spin Polaron in Lightly Doped CuO Planes"
Wei-Cheng Lee, T. K. Lee
In a recent Letter (Phys. Rev. Lett. 106, 036401 (2011)), Lau, et al. investigated the single hole problem in an effective model containing Cu and O orbitals by exact diag…
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…
Effect of the Fermi surface destruction on transport properties in underdoped cuprates
Jian-Xin Li, W. C. Wu, T. K. Lee
Motivated by recent experimental measurements on the Fermi surface(FS) destruction in underdoped high- cuprates, we examine its effect on the transport properties based on t…
Phase diagram of the two-chain Hubbard model
Youngho Park, Shoudan Liang, T. K. Lee
We have calculated the charge gap and spin gap for the two-chain Hubbard model as a function of the on-site Coulomb interaction and the interchain hopping amplitude. We used the de…
Variational Study of the Spin-Gap Phase of the One-Dimensional t-J Model
Y. C. Chen, T. K. Lee
We propose a correlated spin-singlet-pairs wave function to describe the spin-gap phase of the one-dimensional model at low density. Adding a Jastrow factor with a variationa…
Dispersion of a single hole in the t-J model
T. K. Lee, C. T. Shih
The dispersion of a single hole in the t-J model obtained by the exact result of 32 sites and the results obtained by self-consistent Born approximation and the Green function Mont…
t-J model Studied by the New Lanczos-Power Method
Y. C. Chen, T. K. Lee
The initial trial wave function used in a simple ground-state projection method, the power method, is systematically improved by using Lanczos algorithm. Much faster convergence to…
Is there spin-charge separation in the 2D Hubbard and t-J models at low electronic densities?
Y. C. Chen, A. Moreo, F. Ortolani +2
The spin and density correlation functions of the two-dimensional Hubbard model at low electronic density are calculated in the ground state by using the power method, and at…
