Survival Law in a Potential Model
Abstract. The radial equation of a simple potential model has long been known to yield an exponential survival law in lowest order (Breit-Wigner) approximation. We demonstrate that if the calculation is extended to fourth order the survival law exhibits a parabolic short time behavior which leads to the quantum Zeno effect. This model has further been studied numerically to characterize the ext...
متن کاملan appropriate model for exchange rate predictability in iran: comparing potential forecastability
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
Heavy Quarkonia Survival in Potential Model
We investigate the quarkonia correlators in QCD with no light quarks within a potential model with different screened potentials. Our results for the temperature dependence of the charmonium and bottomonium correlators are qualitatively consistent with existing and preliminary lattice results. We identify however, a much reacher structure in the correlators than the one seen on the lattice. PAC...
متن کاملEffects of Valve Closing Law and Unsteady Friction Model on Damping Pressure Waves in a Network
Water-hammer is a transient condition which may occur in a network as a result of rapid or slow valve closures, pump failures, changes in turbine loading, etc. It creates high and low pressure waves which travel along the system and decay as a result of wall shear stress. Comparison o experimental and theoretical results revealed the failure of steady or quasi-steady models in correctly predict...
