High Energy Process

A new structure for the high-energy diffractive scattering amplitude is derived in two complementary ways (one of them recently revealed as due to Richard Feynman). Total cross-sections increase, due to a blackening of the interaction and also due to an effect which leads to an increase in the effective interaction area at fixed opacity. These features are dynamically related to the dominant high-energy process of multiparticle production.

Very High

We study the meditative states of human beings from the conceptual framework provided by the fractaquantum hypothesis : analogously to an atom, Man can from his ``quiet'' base state explores various states of higher energy as loving or mystical state. We then look what energy states are explored during meditation: is it the ``hyperfine'' structure of its base state? is there a love ecstatic state? a very high energy structure mystical state? On one hand we illustrate these hypothesis from the experience of a large part of mystical traditions such as Hinduism or Buddhism and on another hand from contemporary cognitive sciences. In addition, quantum mechanics indicates that any interaction between energy levels is mediated by a boson of exchange. So we aim to identify the nature of this boson linking the various human being energy levels.

Molecular Dynamics Methods

To study the kinetic properties of dense quantum plasma, a new quantum dynamics method in the Wigner representation of quantum mechanics has been developed for extreme conditions, when analytical approximations based on different kinds of perturbation theories cannot be applied. This method combines the Feynman and Wigner formulation of quantum mechanics and uses for calculation the path integral Monte-Carlo (WPIMC) in phase space and quantum generalization of the classical molecular dynamics methods (WMD) allowing to solve the quantum Wigner–Liouville-like equation. The Fermi–Dirac statistical effects are accounted for by the effective pair pseudopotential depending on coordinates and momenta and allowing to avoid the famous “sign problem” due to realization of the Pauli blocking of fermions. Significant influence of the interparticle interaction on the high energy asymptotics of the momentum distribution functions have been observed. According to the quantum Kubo formula, we also study the electron conductivity of dense plasma media.
