Statistical Properties Hidden in Complex Systems : On the Basis of the Lognormal Distribution

The normal distribution is believed to be a universal distribution in nature. However, we often find many examples which obey skewed distributions, such as the power-law and the lognormal distributions, in both natural and social phenomena. In this article we demonstrate novel and various examples which obey the lognormal distributions and try to explain why the lognormal behavior is often observed in complex systems.

One-Dimensional State and Superfluidity of ⁴He Nanotubes

⁴He Bose fluids from three-dimensional (3D) to 1D states have been realized by using nanopores and flat substrates. The ⁴He films formed in the 3D nanopores show a 3D superfluid transition. The ⁴He fluids in the lower dimensions show superfluidity depending on measurement frequencies and system sizes. In the 2D films, superfluidity was observed at extremely high measurement frequencies in the normal fluid state above the Kosterlitz-Thouless transition temperature. The ⁴He nanotubes formed in 1D nanopores set in the 1D phonon state and show the superfluidity. The 2π-phase winding in the scale of the 1D length and "phase slip" play the main roles for the observation of superfluidity in the 1D state.

It has been long since the existence of dark matter had been proposed. Although it is expected that an unknown particle is responsible for the dark matter, we do not know anything about it up to present. But recent developments on various experiments might make it possible to detect dark matter. In this article recent results and perspectives on dark matter direct detection experiments are presented.

It was over sixty years ago when I first met Professor Toda as a sophomore physics student of Tokyo Bunrika Daigaku (Tokyo University of Literature and Science) whose size was very small. There were only eight students in my class. Professor Toda sees through us carefully and taught us the charm and depth of the physics research according to the level of understanding of students. The author also nostalgically describes Toda's dignified and warm personality accompanied with a sense of humor.

The achievements of Professor Morikazu Toda (Professor emeritus, Tokyo University of Education) are reviewed. In particular, in the study of one-dimensional lattice dynamics, how he invented the exponential potential is explained based on his original papers. A one-dimensional lattice where particles are connected with the exponential potential is now called the Toda lattice. A discovery of the Toda lattice has contributed to the establishment of the soliton concept and has developed significantly the soliton theory. This achievement is a remarkable result of the fundamental physics research in Japan.

The long-term study project 'Dynamical Problems in Statistical Physics' started in 1961. In association with it meetings were held in various places for the study of 'lattice vibration of imperfect crystals' and 'dynamical processes of vibration systems' Dr. Toda leaded the meetings and the results of studies were promptly published in the Supplement of the Progress of Theoretical Physics. Participants of the meetings became to be called 'lattice dynamics group'. Remembering the group, I discuss how the famous Toda lattice became to be invented, and how the personal contacts made by the group encouraged develpments of various fields in statistical physics, dynamical system theory, and probability theory in mathematics.

Professor Morikazu Toda continued to write many serial articles in a mathematical magazine "Suugaku Seminar", for 20 years from 1970. Those titles are "Omocha Seminar-Essays on Science of Toys", "Motion and Figure", "Introduction to Elliptic Function", "Nonlinear Wave and Soliton", etc. This essay has been written about memories of prof. M. Toda and his many articles by an editor of the Suugaku Seminar.
