The conventional Friedmann cosmology is known to be in tension with the existence of stable particles having interaction strength typical for supersymmetry and heavier than several TeV. A possible way save life such may a modification standard cosmological expansion law that density these heavy relics would significantly reduced. We study particle creation Starobinsky inflationary model differe...

Collisions of actinide nuclei form, during very short times of few zs (10−21 s), the heaviest ensembles of interacting nucleons available on Earth. Such collisions are used to produce super-strong electric f elds by the huge number of interacting protons to test spontaneous positron-electron pair emission (vacuum decay) predicted by the quantum electrodynamics (QED) theory. Multi-nucleon transf...

Alexander Vilenkin Institute of Cosmology, Department of Physics and Astronomy, Tufts University, Medford, MA 02155, USA Topological defects can naturally be formed soon after bubble nucleation in the open inflation scenario. The defects are not completely diluted away by the subsequent period of inflation in the bubble interior and can produce observable large-scale microwave background anisot...

Systematic studies of isotopic chains including nuclides from the proton to the neutron dripline are an ideal testing ground for nuclear structure theory. Results of Hartree{Fock calculations for magnesium and tin isotopes are discussed. Ground states and the multipole response of superheavy nuclei are investigated with HF and RPA calculations. Exploratory calculations for single nucleon transf...

A model of competition between complete fusion and quasifission channels in fusion of two massive nuclei is extended to include the influence of dissi-pative effects on the dynamics of nuclear fusion. By using the multidimen-sional Kramers-type stationary solution of the Fokker–Planck equation, the fusion rate through the inner fusion barrier in mass asymmetry is studied. Pu reactions used for ...

Hartree-Fock calculations with the SKX Skyrme interaction are carried out to obtain a-decay Q values for deformed nuclei above Pb assuming axial symmetry. The results for even-even nuclei are compared with the experiment and with the previous calculations. Predictions are made for a-decay Q values and half-lives of even-even superheavy nuclei. The results are also compared for the recently disc...
