    Questionnaire-Based Social Research on Opinions of Japanese Visitors for Communication Robots at an Exhibition.Tatsuya Nomura, Takugo Tasaki, Takayuki Kanda, Masahiro Shiomi, Hiroshi Ishiguro & Norihiro Hagita - 2007 - AI and Society 21 (1-2):167-183.
    This paper reports the results of questionnaire-based research conducted at an exhibition of interactive humanoid robots that was held at the Osaka Science Museum, Japan. The aim of this exhibition was to investigate the feasibility of communication robots connected to a ubiquitous sensor network, under the assumption that these robots will be practically used in daily life in the not-so-distant future. More than 90,000 people visited the exhibition. A questionnaire was given to the visitors to explore their opinions of the (...)

    On the Time Scales in the Approach to Equilibrium of Macroscopic Quantum Systems.Hal Tasaki, Sheldon Goldstein & Takashi Hara - unknown
    The recent renewed interest in the foundation of quantum statistical mechanics and in the dynamics of isolated quantum systems has led to a revival of the old approach by von Neumann to investigate the problem of thermalization only in terms of quantum dynamics in an isolated system [1, 2]. It has been demonstrated in some general or concrete settings that a pure initial state evolving under quantum dynamics indeed approaches an equilibrium state [3–9]. The underlying idea that a single pure (...)

    Measurement Theory in the Lax-Phillips Formalism.S. Tasaki, E. Eisenberg & L. P. Horwitz - 1994 - Foundations of Physics 24 (8):1179-1194.
    It is shown that the application of the Lax-Phillips scattering theory to quantum mechanics provides a natural framework for the realization of the ideas of the “Many-Hilbert-Space” theory of Machida and Namiki to describe the development of decoherence in the process of measurement. We show that if the quantum mechanical evolution is pointwise in time, then decoherence occurs only if the Hamiltonian is time-dependent. If the evolution is not pointwise in time (as in Liouville space), then the decoherence may occur (...)

    Contents.Hal Tasaki, Sheldon Goldstein & Takashi Hara - unknown
    We study the problem of the approach to equilibrium in a macroscopic quantum system in an abstract setting. We prove that, for a typical choice of “nonequilibrium subspace”, any initial state (from the energy shell) thermalizes, and in fact does so very quickly, on the order of the Boltzmann time τ B := h/(k B T ). This apparently unrealistic, but mathematically rigorous, conclusion has the important physical implication that the moderately slow decay observed in reality is not typical in (...)

    Quantum Mechanics and the Direction of Time.H. Hasegawa, T. Petrosky, I. Prigogine & S. Tasaki - 1991 - Foundations of Physics 21 (3):263-281.
    In recent papers the authors have discussed the dynamical properties of “large Poincaré systems” (LPS), that is, nonintegrable systems with a continuous spectrum (both classical and quantum). An interesting example of LPS is given by the Friedrichs model of field theory. As is well known, perturbation methods analytic in the coupling constant diverge because of resonant denominators. We show that this Poincaré “catastrophe” can be eliminated by a natural time ordering of the dynamical states. We obtain then a dynamical theory (...)
