Mesh-based Autoencoders for Localized Deformation Component AnalysisSep 13 2017Dec 16 2017Spatially localized deformation components are very useful for shape analysis and synthesis in 3D geometry processing. Several methods have recently been developed, with an aim to extract intuitive and interpretable deformation components. However, these ... More
Quantum switch for single-photon transport in a coupled superconducting transmission line resonator arrayApr 06 2009Jul 28 2009We propose and study an approach to realize quantum switch for single-photon transport in a coupled superconducting transmission line resonator (TLR) array with one controllable hopping interaction. We find that the single-photon with arbitrary wavevector ... More
Symmetry of Generalized Randall-Sundrum Model and Distribution of 3-Branes in Six-Dimensional SpacetimeJun 11 2015A generalization from the usual $5$-dimensional two-brane Randall-Sundrum (RS) model to a $6$-dimensional multi-brane RS model is presented. The extra dimensions are extended from one to two; correspondingly the single-variable warp function is generalized ... More
Particle collisions in the lower dimensional rotating black hole space-time with the cosmological constantFeb 19 2012Mar 11 2014In this paper, we study the effect of ultra-high energy collisions of two particles with different energies near the horizon of a 2+1 dimensional BTZ black hole (BSW effect). We find that the particle with the critical angular momentum could exist inside ... More
A critical point in Sr2-xIrO4 and less distorted IrO6 octahedra induced by deep Sr-vacanciesOct 31 2016For the Sr2-xIrO4 system, recent work pointed out the abnormal electronic and magnetic properties around the critical point. Here, to understand Sr-vacancy effect on spin-orbit coupled Mott insulator Sr2IrO4, the electronic structure and local structure ... More
Early thermalization of quark-gluon matter with the elastic scattering of ggq and ggqbarMay 22 2013Elastic gluon-gluon-quark (gluon-gluon-antiquark) scattering is studied in perturbative QCD with 123 Feynman diagrams at the tree level. Individually squared amplitudes and interference terms of the Feynman diagrams are derived. With the elastic gluon-gluon-quark ... More
