We study the influence of disorder strength on the interface roughening process in a phase-field model with locally conserved dynamics. We consider two cases where the mobility coefficient multiplying the locally conserved current is either constant throughout the system (the two-sided model) or becomes zero in the phase into which the interface advances (one-sided model). In the limit of weak ...

The deconfinement phase transition is studied in the ensemble canonical with respect to triality. Since this ensemble implies a projection to the zero triality sector of the theory we introduce a quantity which is insensitive to Z(N c) symmetry but can reveal a critical behaviour in the theory with dy-namical quarks. Further, we argue that in the canonical ensemble description of full QCD there...

Bound on V + A admixture in the b → c current from inclusive vs. exclusive semileptonic decays of B mesons. Abstract An admixture of a right-handed b → c current in the semileptonic weak decays of the B mesons would give a significantly different contribution to the inclusive rate of the decays B → l ν X c as compared to the exclusive decay B → D * l ν at zero recoil. Thus a difference in the v...

thin films of binary bi 0 -teo and bi 0 -v 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. the optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a perkin-elmer uv/vis spectrophotometer. it is found that the value of n=3/2 in the davis-mott equation is best fitted for the fundamental absorption edge for the...
