 | Wu, Yong-Shi | Deformed Hubbard operator, bosonization, and phase diagram of the one-dimensional t-J model | We present an analytic study of the phase diagram of the one-dimensional t-J model and a couple of its cousins. To deal with the interactions induced by the no double occupancy constraints, we introduce a deformation of the Hubbard operators. When the deformation parameter ∆ is small, the induced... | Hubbard operator; Bosonization; Deformation; t-J model | 2002-10 |

 | Hansen, Charles D.; Whitaker, Ross T. | Interactive deformation and visualization of level set surfaces using graphics hardware | Deformable isosurfaces, implemented with level-set methods, have demonstrated a great potential in visualization for applications such as segmentation, surface processing, and surface reconstruction. Their usefulness has been limited, however, by their high computational cost and and reliance on sig... | Deformation; Level sets; Deformable models; Image segmentation; Volume visualization; GPU; Streaming computation; Isosurfaces | 2003 |

 | Wu, Yong-Shi | Remarks on noncommutative open string theory: V duality and holography | In this paper we study the interplay of electric and magnetic backgrounds in determining the decoupling limit of coincident D branes towards a noncommutative Yang-Mills (NCYM) or open string (NCOS) theory. No decoupling limit has been found for the NCYM model with space-time noncommutativity. It i... | Hubbard operator; Bosonization; Deformation; t-J model | 2001-03 |
