Noncommutativity and its role in constant-roll inflation models with non-minimal coupling constrained by swampland conjectures
《Chinese Physics C》2025年第2期237-254,共18页Saeed Noori Gashti Mohammad Reza Alipour Mohammad Ali S.Afshar Jafar Sadeghi 
In this paper,using Hamiltonian formalism,we obtain solutions for constant-roll inflation according to the noncommutativity and the non-minimal coupling field of the Lagrangian.We consider three different types of cou...

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(...

Interacting Theory of Chiral Bosons and Gauge Fields on Noncommutative Extended Minkowski Spacetime
《Communications in Theoretical Physics》2012年第5期855-865,共11页缪炎刚 赵英杰 
Supported in part by the National Natural Science Foundation of China under Grant No.11175090;the Fundamental Research Funds for the Central Universities under Grant No.65030021;the Project of Knowledge Innovation Program (PKIP) of Chinese Academy of Sciences under Grant No.KJCX2.YW.W10
Several interacting models of chiral bosons and gauge fields are investigated on the noncommutative extended Minkowski spacetime which was recently proposed from a new point of view of disposing noncommutativity.The m...

Effects of Spatial Noncommutativity on Energy Spectrum of a Trapped Bose-Einstein Condensate被引量：1
《Communications in Theoretical Physics》2006年第6X期966-968,共3页LUO You-Hua GE Zi-Ming 
The project supported in part by National Natural Science Foundation of China under Grant No. 10174086. Luo greatly appreciates Prof. J.Z. Zhang for valuable discussions.
In noncommutative space, we examine the problem of a noninteracting and harmonically trapped Bose- Einstein condensate, and derive a simple analytic expression for the effect of spatial noncommutatlvity on energy spec...

Phase Semantics for a Pure Noncommutative Linear Propositional Logic被引量：1
《Journal of Computer Science & Technology》1999年第2期135-139,共5页应明生 
We use a many-sorted language to remove commutativity from phase semantics of linear logic and show that pure noncommutative intuitionistic linear propositional logic plus two classical rules enjoys the soundness and ...
