the rock masses in a construction site of underground cavern are generally not continuous, due to the presence of discontinuities, such as bedding, joints, faults, and fractures. the performance of an underground cavern is principally ruled by the mechanical behaviors of the discontinuities in the vicinity of the cavern. during underground excavation, many surrounding rock failures have close r...

We review the nuclear parton distribution functions computed on the basis of our microscopic model taking into account a number of nuclear effects including Fermi motion and nuclear binding, nuclear meson-exchange currents, off-shell corrections to bound nucleon distributions and nuclear shadowing. We discuss applications to a number of different processes including leptonnucleus deep inelastic...

For the case of finite life-time broadening the standard Kubo-formula for the optical conductivity tensor is rederived in terms of Green’s functions by using contour integrations, whereby finite temperatures are accounted for by using the Fermi-Dirac distribution function. For zero life-time broadening, the present formalism is related to expressions well-known in the literature. Numerical aspe...

We introduce a unified Gaussian quantum operator representation for fermions and bosons. The representation extends existing phase-space methods to Fermi systems as well as the important case of Fermi–Bose mixtures. It enables simulations of the dynamics and thermal equilibrium states of many-body quantum systems from first principles. As an example, we numerically calculate finite-temperature ...

Influence of asymmetry on superfluidity of nuclear matter with triplet–singlet pairing of nucleons (in spin and isospin spaces) is considered within the framework of a Fermi–liquid theory. Solutions of self–consistent equations for the critical temperature and the energy gap at T = 0 are obtained with the use of Skyrme effective nucleon interaction. It is shown, that if the chemical potentials ...
