We study the dynamics of a double-well BEC system subjected to oscillating dissipation. The macroscopic model is described within the mean-field approximation while the noise effect due to large reservoir fluctuation has been averaged out to zero. We chose a simple dissipative memory kernel to produce a time-dependent oscillating dissipation. Our numerically calculated phase-space portraits and Lyapunov exponents show an enhanced route to chaos as one increases the driving dissipation amplitude.

We present one-loop formulas for contributing to the HZZ vertex in ’t Hooft-Veltman gauge within Standard Model framework. One-loop off-shell Higgs decay rates to Z-pair are investigated in both unpolarized and longitudinal polarization for Z bosons in final state. The corrections are range of 7% to 8.4% when we vary the off-shell Higgs mass from 200 GeV to 500 GeV.

Carbon quantum dots (CQDs) are a new blooming carbon containing nanoparticles having size of less than 10 nm. They have wide range of application in the field of sensing of inorganic analytes, bio sensing, cell imaging, studying biological processes in living cells and also for drug delivery. T. In this review article we demonstrate how these tools are used to characterize newly synthesized CQDs, monitor the synthesis process along with finding its application in numerous fields.
