The dynamical creation/annihilation of a Dp-brane from D(p-2)branes
《Communications in Theoretical Physics》2021年第3期55-63,共9页Xiaoying Zhu 
The author would like to thank J X Lu for fruitful discussion and acknowledge support by a grant from the NNSF of China with Grant No:11775212.
We discuss how to generate a dynamical Dp-brane with a topology of R^(p-2)×S^(2) from N D(p-2)-branes with R^(p-2) topology with or without the presence of a constant RR(p+2)-form flux.This extends the previous work(...

Computing parallel/coincident phase D-brane superpotentials and Type-Ⅱ/F-theory duality
《Chinese Physics C》2018年第9期37-46,共10页Xiao-Tian Jiang Fu Zhong Yang 
Supported by NSFC(11475178) and Y4JT01VJ01
In this paper we study the parallel phase and the coincident phase of D-brane systems with the compactification of one closed modulus. D-brane systems with two phases are described by different 4-folds in terms of Ty...

Mirror symmetry,D-brane superpotentials and Ooguri-Vafa invariants of Calabi-Yau manifolds被引量：1
《Chinese Physics C》2015年第12期7-12,共6页张姗姗 杨富中 
Supported by Y4JT01VJ01;NSFC(11475178)
The D-brane superpotential is very important in the low energy effective theory. As the generating function of all disk instantons from the worldsheet point of view, it plays a crucial role in deriving some important ...

D-brane superpotentials and Ooguri-Vafa invariants of compact Calabi-Yau threefolds
《Chinese Physics C》2015年第4期19-25,共7页徐锋军 杨富中 
Supported by NSFC(11075204,11475178)
We calculate the D-brane superpotentials for two compact Calabi-Yau manifolds X14（1,1,2,3,7） and Xs （1,1,1,2,3） which are of non-Fermat type in the type II string theory. By constructing the open mirror symmetry, ...

D-Brane的相互作用
《中国科技纵横》2014年第6期227-228,232,共3页赵新彦 陈明 
D膜对于超弦理论及M理论的非微扰性质非常重要,本文主要研究D膜之间的相互作用以及相关的动力学问题。类似于QFT,Feynman图并不能捕捉所有的信息,弦理论中的微扰展开也无法给出所有的现象,因此非微扰理论是必须的。非微扰论主要有：弦...

String Gauge Symmetries in the Conformally Gauge-Fixed Polyakov D1 Brane Action in the Presence of Background Gauge Fields被引量：1
《Journal of Modern Physics》2012年第1期110-115,共6页Usha Kulshreshtha Daya Shankar Kulshreshtha 
Recently we have studied the instant-form quantization (IFQ) and the light-front quantization (LFQ) of the conformally gauge-fixed Polyakov D1 brane action using the Hamiltonian and path integral formulations. The IFQ...

Accelerated D-Dimensional Compactified Universe in Gauss-Bonnet-Dilatonic Scalar Gravity from D-Brane/M-Theory
《Chinese Physics Letters》2008年第8期2785-2788,共4页EL-NABULSI Ahmad Rami 
We discuss a particular d-dimensional Gauss- Ronnet-dilatonie universe compactified on S^1 motivated from Mtheory. We examine the time-evolution of the dynamical equations where many interesting consequences are revea...
