Opis:: Experimental results of irradiation effects by heavy ions with high inelastic energy losses at the surfaces of some amorphous alloys are presented. It was shown that all studied alloys strongly swelled: up to 15% for Ni58Nb42 under irradiation with the 305 MeV 86Kr ion at a fluence of 1015 ion/cm2. Besides, the sputtering (evaporation) process takes place, too. Calculations of the temperatures on the ion trajectory axis were presented. It was shown that the calculated temperatures are higher than the melting temperature and the evaporation temperature, too. From these findings we can conclude that the sputtering (evaporation) of atoms in amorphous alloys is present.

Opis:: We report on an analytical study of the statistics of conductance, g, and shot-noise power, p, for a chaotic cavity with arbitrary numbers N$\text{}_{1,2}$ of channels in two leads and symmetry parameterβ = 1, 2, 4. With the theory of Selberg's integral the first four cumulants of g and first two cumulants of p are calculated explicitly. We give analytical expressions for the conductance and shot-noise distributions and determine their exact asymptotics near the edges up to linear order in distances from the edges. For 0 < g < 1 a power law for the conductance distribution is exact. All results are also consistent with numerical simulations.

Opis:: Wave scattering in chaotic systems with a uniform energy loss (absorption) is considered. Within the random matrix approach we calculate exactly the energy correlation functions of different matrix elements of impedance or scattering matrices for systems with preserved or broken time-reversal symmetry. The obtained results are valid at any number of arbitrary open scattering channels and arbitrary absorption. Elastic enhancement factors (defined through the ratio of the corresponding variance in reflection to that in transmission) are also discussed.
