    A cellular-automaton model for cooperative effects in matter-radiation interaction: the semiconductor laser

    A two-dimensional cellular-automaton (CA) model is proposed for a semiconductor laser system, showing qualitative behaviour in agreement with actual performances.The relevance of this approach to the descripti...

    Biosystem response to soft-X-rays irradiation: non-monotonic effects in the relevant biological parameters of yeast cells

    Soft-X-rays irradiation of yeast cells allows selective interference with different cellular structures. The monitoring of different physical parameters leads to substantial variations in the response to X-ray...

    Bioenergetics control by light: laser effects on a human-cell line (EUE) and yeast cells

    Short-time effects due to low-power, low-energy (HeNe and GaAs) laser irradiation were studied in two cellular systems: an embryonal-human-cell line (EUE) and yeast cells (Saccharomyces cerevisiae). In EUE cells ...

    The electromagnetic interaction in the enzyme activity involving ATP

    A two-level model is considered to describe the dynamics of a biological system undergoing cyclic transformations between two states separated by an energy quantum interval. This is typically met in enzyme-act...

    Semiconductor lasers and optical feedback

    Experimental work and theoretical discussion on microscopic processes and device behaviours are presented. The presence of optical feedback from the environment induces asymmetries in the system affecting prac...

    On the quantum-mechanical description of Josephson junctions

    We calculate in exact closed form the commutator and the anticommutator of the collective operators which describe pair transfer in a Josephson junction. We determine the conditions under which the exact commu...

    Use of a coherent-state formalism in superconductivity and Josephson-junction calculations

    An investigation is made of the extent to which harmonic-oscillator coherent states can be used to describe superconductivity and Josephson tunneling phenomena. Recent work has utilized angular-momentum commut...
