We report a ring cavity passively harmonic mode-locked thulium-doped fiber laser (TDFL) using a newly developed single-wall carbon nanotube-based saturable abso
The electrons in graphene behave like massless Dirac chiral particles with velocity vF,approximately 1/300 speed of light.[1-4] This salient properties make the
We investigate analytically and numerically the dynamics of the Rikitake system.The Routh-Hurwitz criterion is used to study the stability of the equilibrium po
The Josephson currents through real vector potential (RVP) and pseudo vector potential (PVP) barriers in graphene are investigated.In graphene,the pseudo vector
