نویسندگان

چکیده

A model is developed to calculate the total kinetic energy (TKE) distribution of fission fragments in framework time-dependent generator coordinate method (TDGCM), extended include dissipation effects description induced dynamics. Starting from an expression for dissipative term GCM Hamiltonian that determines time evolution a statistical collective wave function, derived first part this work, integrated flux probability current through scission hyper-surface can be computed at different temperatures. The specific pair given temperature determined by balance formula. By folding energies with current, TKE calculated. illustrated calculation $^{228}$Th, 3D space coordinates: axially-symmetric quadrupole and octupole deformations, nuclear temperature.

Investigation of the two-machine flow shop scheduling problem to minimize total energy costs with time-dependent energy prices

In this paper, the problem of two-machine flow shop scheduling to minimize total energy costs under time-of-use tariffs is investigated. As the objective function of this study is not a regular measure, allowing intentional idle-time can be advantageous. So this study considers two approaches, one for non-delay version of the problem and the other one for a situation when inserting intentional ...

Time-Dependent Real-Space Renormalization Group Method

In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...

Fission dynamics within time-dependent Hartree-Fock: Boost-induced fission

Methods: Following upon the work presented in Ref. [1], quadrupole-constrained Hartree-Fock calculations are used to create a potential energy surface. An isomeric state and a state beyond the second barrier peak are excited by means of instantaneous as well as temporally extended gauge boosts with quadrupole shapes. The subsequent deexcitation is studied in a time-dependent Hartree-Fock simula...

Fission dynamics within time-dependent Hartree-Fock: deformation-induced fission

Studies of nuclear fission have been ongoing since the discovery of the process in 1938 by Hahn and Strassmann [1]. The actinide nuclide Pu has long been a case of interest, as spontaneous fission presents itself as a decay mechanism with significant probability, relative to other isotopes in the actinide region. This allows for quantitative comparisons between spontaneous and induced fission [...
