Based on the Veneziano ghost theory of QCD, we estimate the cosmological constant Λ, which is related to the vacuum energy density, , by =8πG . In the recent Veneziano ghost theory is given by the absolute value of the product of the local quark condensate and quark current mass: =(2NfH/m)*c|mq<0|:qq:|0>|.By solving Dyson-Schwinger Equations for a dressed quark propagator, we found the local quark condensate;-(235 MeV)3, the generally accepted value. The quark current mass is mq 4.0 Mev. This gives the same result for as found by previous authors, which is somewhat larger than the observed value. However, when we make use of the nonlocal quark condensate, =g(x), with g(x) estimated from our previous work, we find Λ is in a good agreement with the observations. 展开更多

A long Josephson junction can be modeled by a perturbed sine-Gordon equation. Based on a soliton perturbation theory, the probability distribution of the velocity of a single soliton, at the presence of a white noise contained in bias current, is studied by the Fokker-Planck method. This approach can be extended to the study of multisolitons. 展开更多
