Theory of an infinitely anisotropic phase of a two-dimensional superconductor
Zi-Xiang Li, Steven A. Kivelson, Dung-Hai Lee
We propose a simple model of a two-dimensional ``locally smectic superconductor'' that exhibits power-law non-linear I-V characteristics with different powers for current applied i…
The Structure of a Vortex in the t-J Model
Jung Hoon Han, Dung-Hai Lee
We study the single-vortex solution of the t-J model within resonating-valence-bond (RVB) mean-field theory. We find two types of vortex cores, insulating and metallic, depending o…
Critical Conductance and Its Fluctuations at Integer Hall Plateau Transitions
Ziqiang Wang, Božidar Jovanović, Dung-Hai Lee
Under periodic boundary condition in the transverse direction, we calculate the averaged zero-temperature two-terminal conductance () and its statistical fluctuations ($<(\dg)…
Composite quasiparticle formation and the low-energy effective Hamiltonians of the one- and two-dimensional Hubbard Model
Junwu Gan, Dung-Hai Lee, Per Hedegard
We investigate the effect of hole doping on the strong-coupling Hubbard model at half-filling in spatial dimensions . We start with an antiferromagnetic mean-field descript…
The Effects of Electron-Electron Interactions on the Integer Quantum Hall Transitions
Dung-Hai Lee, Ziqiang Wang
We study the effects of electron-electron interaction on the critical properties of the plateau transitions in the {\it integer} quantum Hall effect. We find the renormalization gr…
Network Models of Quantum Percolation and Their Field-Theory Representations
Dung-Hai Lee
We obtain the field-theory representations of several network models that are relevant to 2D transport in high magnetic fields. Among them, the simplest one, which is relevant to t…
