　View Summary

To study the establishment of homochirality observed in the
crystal growth experiment
of chiral molecules from a solution under grinding,
we extend the lattice gas model of crystal growth as follows.
A lattice site can be occupied by a chiral molecule in R or S form,
or can be empty.
Molecules form homoclusters by nearest neighbor bonds.
They change their chirality if they are isolated monomers
in the solution.
Grinding is incorporated by cutting and shafling the system randomly.
It is shown that Ostwald ripening without grinding is extremely slow
to select chirality, if possible.
Grinding alone also cannot achieve chirality selection.
For the accomplishment of homochirality, we need
an enhanced chirality change on crystalline surface. With
this "autocatalytic effect" and the recycling of monomers
due to grinding, an exponential increase of
crystal enantiomeric excess to homochiral state is realized.

Heteroepitaxial Growth Modes with Dislocations in a Two-Dimensional Elastic Lattice Model

Hiroyasu Katsuno, Makio Uwaha and Yukio Saito

Surface Science 602 ( 22 ) 3461-3466 2008.11

Research paper (scientific journal), Joint Work

　View Summary

We study equilibrium shapes of adsorbate crystals
by allowing a possibility of
dislocations on an elastic substrate in a two-dimensional lattice model.
The ground state energy is calculated numerically with the use of an elastic lattice Green's function.
From the equilibrium shapes determined for various coverages,
we infer the growth mode.
As the misfit parameter increases,
the growth mode changes
from the Frank-van der Merwe (FM)
to the Stranski-Krastanov (SK),
further to the FM with dislocations
for a parameter range of ordinary semiconductor materials.
Conceivable growth modes such as the SK with dislocations
appear in a parameter range
between the SK and the FM with dislocations.

Fluctuation Induced Homochirality

TAKESHI SUGIMORI, HIROYUKI HYUGA and SAITO YUKIO

J. Phys. Soc. Jpn 77   064606(1-6) 2008.06

Research paper (scientific journal), Joint Work

　View Summary

We propose a new mechanism
for the achievment of homochirality in life
without any autocatalytic production process.
Our model consists of a spontaneous production together
with a recycling cross inhibition in a closed system.
It is shown that although
the rate equations for this system predict no chiral symmetry breaking,
the stochastic master equation predicts complete homochirality.
This is because the fluctuation induced by the discreteness of population numbers of participating molecules plays essential roles. This fluctuation conspires with the recyling cross inhibition to realize the homochirality.
