A New Description of the Decay of an Unstable State
An experiment on the time dependent photon tories, solutions of the deterministic equation statistics of a laser [1] opened a long lasting discus= F ~ sion on transient statistics. This is a particularly releX vant subject in so far as the decay of an unstable whose density is weighted by the probability density state is accompanied by anomalous fluctuations P(x0) of the initial conditionx0. No...
متن کاملEnhanced quantum Zeno effect and bunching in the decay of interacting bosons from an unstable state
We theoretically study the decay of two interacting bosons from a leaky trap by tunneling through a potential barrier. Although decay rates are generally enhanced by repulsive interactions, we predict a strong suppression of the decay for short times. This leads to an enhancement of the quantum Zeno effect. Results from perturbation theory are supplemented by numerical calculations of the eigen...
متن کاملFinal State Interaction Effects in B+→J/ψ π+ Decay
In this research the exclusive decay of is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...
متن کاملOpen Systems - Unstable Particle Decay in Medium
The problem of unstable particle decay is discussed to show how elementarity of a subsystem immersed in an infinitely larger environment is lost. The decay law, when the same kind of particles as decay product make up a thermal medium, is worked out in detail. The relic abundance of unstable particles does not suffer from the Boltzmann suppression crucial at very low temperatures, because the o...
متن کاملNoise delayed decay of unstable states: theory versus numerical simulations
We study the noise delayed decay of unstable nonequilibrium states in nonlinear dynamical systems within the framework of the overdamped Brownian motion model. We give the exact expressions for the decay times of unstable states for polynomial potential profiles and obtain nonmonotonic behavior of the decay times as a function of the noise intensity for the unstable nonequilibrium states. The a...
