Comparison of the and operator approximations for the two-dimensional t-J model
Youngho Park
We compare the spectra of the new operator of the SO(5) theory and the conventional operator for the two-dimensional t-J model. We also calculate the weight transferred to…
Charge and spin dynamics of the Hubbard chains
Youngho Park, Shoudan Liang
We calculate the local correlation functions of charge and spin for the one-chain and two-chain Hubbard model using the density matrix renormalization group method and the recursio…
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…
Dynamical Supersymmetry of a Vortex System with Potential
Younghoon Park, Yongsung Yoon
The Pauli Hamiltonian for a spin charged particle interacting with a point magnetic vortex and potential exhibits a dynamical supersymmetry on th…
