Numerical Study of Induced False Vacuum Decay at High Energies
We calculate numerically the probability exp[ λF (E/Esph, N/Nsph)] of the false vacuum decay in the massive four-dimensional−λφ4 model from multiparticle initial states with fixed number of particles N and energy E greater than the height of the barrier Esph. We find that at E ∼< 3Esph and N ∼< 0.4Nsph the decay is classically forbidden and thus is exponentially suppressed. We argue that the cl...
متن کاملEfficient Numerical Solution of PIDEs in Option Pricing Efficient Numerical Solution of PIDEs in Option Pricing
The estimation of the price of different kinds of options plays a very important role in the development of strategies on financial and stock markets. There many books and various papers which are devoted to the exist mathematical theory of option pricing. Merton and Scholes became winners of a Nobel Prize in economy who described the basic concepts of the mathematical theory development. In th...
متن کاملNumerical Solution and Exponential Decay to Von Kármán System with Frictional Damping
In this work we consider the Von Kármán system with frictional damping acting on the displacement and using the Method of Nakao we prove the exponential decay of the solution. The numerical scheme is presented for calculate the solution and to verify the long-time decay energy.
متن کاملInterpreting Cosmological Vacuum Decay
The cosmological vacuum decay scenario recently proposed by Wang and Meng [1] is rediscussed. From thermodynamic arguments it is found that the ǫ parameter quantifying the vacuum decay rate must be positive in the presence of particle creation. If there is no particle creation, the proper mass of Cold Dark Matter (CDM) particles is necessarily a time dependent quantity, scaling as m(t) = moa(t)...
متن کاملFalse Vacuum Decay after Inflation
Inflation is terminated by a non-equilibrium process which finally leads to a thermal state. We study the onset of this transition in a class of hybrid inflation models. The exponential growth of tachyonic modes leads to decoherence and spinodal decomposition. We compute the decoherence time, the spinodal time, the size of the formed domains and the homogeneous classical fields within a single ...
