Superconducting Transition in Doped Antiferromagnet
Ming Shaw, Z. Y. Weng, C. S. Ting
We investigate the superconducting transition in a doped antiferromagnet. Based on the phase string framework of the t-J model, an effective model describing the phase-coherence tr…

High Angular Momentum Core States and Impurity Effects in the Mixed State of d-Wave Superconductors
Jian-Xin Zhu, C. S. Ting, A. V. Balatsky
The local quasiparticle spectra around the vortex core of a d-wave superconductor in the mixed state is studied by solving the lattice Bogoliubov-de Gennes equations self-consisten…

Spin-charge separation: From one hole to finite doping
Z. Y. Weng, D. N. Sheng, C. S. Ting
In the presence of nonlocal phase shift effects, a quasiparticle can remain topologically stable even in a spin-charge separation state due to the confinement effect introduced by…
