Modeling of macroscopic quantum states in functional properties of the laser-induced 4D-topological nanoclusters in thin films on solid surface

Abstract

Nanocluster structures can be easily modified in necessary direction and by controlled way in femto-nanophotonics experiments. The variation of the key topology parameters can result in new type of the quantum correlation states/size effect for charged particles.In our earlier experiments we studied laser-induced topological nanoclusters structures of different types in thin films with unique phenomena in electrophysics and optics (see [1][2][3]). A simple 2-steps mechanism for enhancement of quantum behavior (e.g. in electroconductivity) exists for different conditions. First, when inelastic length linelastic > acluster we have no incoherent electron-phonon (e-ph) scattering, i.e. the coherent process takes place. Second, when de Broglie wave length λdB ≡ ℓcoh > Ʌ, (aclustercluster size , Λspatial period of nanoparticle distribution) the coherent tunneling without loss occurs, and a long-range order with interference of the states takes place in the medium due to lattice structure.Several results of our modeling are shown in both Fig. 1-2 for a topology structures and Fig.3 for the Volt-Ampere characteristics.
