| 1 | Time Varying Gravitational Constant G via Entropic Force显示文摘如果无常原则适用于 Verlinde entropic 想法,它在普朗克常数的规模在牛顿力学的第二条法律导致一个新术语。这个好奇的速度依赖者术语在我们探讨的这封短信启发严肃的一个摩擦特征这个新术语作为时间依赖者数量修改有效的团和牛顿的常数。因此,我们必须有一在 holographic 屏幕和 G 附近在粒子团 m 上在有效的团的价值上跑。这结果有一几乎有关于大数字假设(L.N.H ) 的迪拉克假设的关系。我们建议经由 Verlinde 想法的改正的 entropic 术语能为迪拉克想法的真实性作为一条 holographic 证据被带。 | M.R.Setare D.Momeni | 2011 | Communications in Theoretical Physics2011，56，10： | 1 |
| 2 | Twofold hidden conformal symmetry of Kerr-Bolt black holes显示文摘Previously we have shown that a four-dimensional Kerr-Bolt black hole in non-extremal and also in extremal cases could be described by a holographic two-dimensional (2D) conformal field theory (CFT) [Ghezelbash A M,Kamali V and Setare M R 2010 Phys.Rev.D 82 124051;Setare M R and Kamali V 2010 JHEP 10 074].Motivated by recent work [Chen C M,Huang Y M,Sun J R,Wu M F and Zou S J 2010 Phys.Rev.D 82 066004],we show that there is another holographic description for these black holes.The first description is called the J-picture,whose construction is based on the black hole angular momentum.The new description is called the Q-picture,whose constructions originate from the nut charge of the black hole.Similar to the previous cases [Ghezelbash A M,Kamali V and Setare M R 2010 Phys.Rev.D 82 124051;Setare M R and Kamali V 2010 JHEP 10 074],we show that this new picture for a low frequency limit of the wave equation of a massless charged scalar field in the background of a Kerr-Bolt black hole can be written as the Casimir of SL(2,R) symmetry.Our result shows that the entropy of the black hole is reproduced by the Cardy formula.In addition,the absorption cross section is consistent with the finite temperature absorption cross section for a two-dimensional CFT. | M.R.Setare V.Kamali | 2012 | Chinese Physics B2012，21，2： | 0 |
| 3 | Quantum Hall Effect and Different Zero-Energy Modes of Graphene显示文摘The effect of an inhomogeneous magnetic field,which varies inversely with distance on the ground state energy level of graphene,is studied.We analytically show that graphene under the influence of a magnetic field arising from a straight long current-carrying wire(proportional to the magnetic field from carbon nanotubes and nanowires)exhibits zero-energy solutions and find that contrary to the case of a uniform magnetic field for which the zero-energy modes show the localization of electrons entirely on just one sublattice corresponding to a single valley Hamiltonian,zero-energy solutions in this case reveal that the probabilities for the electrons to be on both sublattices,say A and B,are the same. | M.R.Setare D.Jahani | 2011 | Chinese Physics Letters2011，28，9： | 0 |
