Seminar 1 (15:30〜16:30):
Wetting Sushi (by Prof. J. Indekeu)
ABSTRACT
Bose-Einstein condensation, oil recovery and superconductivity
seem distinct, unrelated topics, that could be displayed
as separate snacks on the menu in a Sushiya. However, they can
be served side by side on the same plate. Indeed, their chemistries
being so very different, we show that the surface physics of these
systems has an intriguing phenomenon in common, which is the
possibility of a wetting phase transition. To begin with, a basic
introduction to Bose Einstein condensation (BEC) is given in this seminar.
Next, recent theoretical predictions of wetting phase transitions are
discussed and experimental observations of wetting are described.
The seminar covers mainly wetting in BEC, additionally wetting
in alkanes on water, and, also, wetting in type-I superconductors.
Seminar 2 (16:45〜17:45):
Structure and Tension of the Contact Line
in Three-Phase Equilibrium (by Prof. B. Widom)
ABSTRACT
With Professor Kenichiro Koga, of Okayama
University, we have analyzed numerically a density-functional
model of the line of contact of three phases, including its
structure and tension. We established numerically that the
model satisfies relations that had earlier been deduced
theoretically, including ones by Professor Joseph Indekeu
in Leuven, Belgium. Of particular interest have been the
behavior of the line tension on approach to a wetting
transition, also that of the boundary tension between
coexisting surface phases on approach to wetting, and the
analog for the contact line of the Gibbs adsorption equation
for interfaces.
