Uwe Grimm has been active in this research area since he joined the
Open University in December 2000. Supported by a research grant from
the Engineering and Physical Sciences Research Council, a group of
post-doctoral researchers, research students and visitors joined from
October 2006.
From September 2007 until March 2008, Uwe Grimm spent six months as
a Visiting Research Associate at the University of Tasmania in Hobart.
In 2009/2010, Michael Baake will spend several months in the group as
a Leverhulme Visiting Professor.
At the 10th International
Conference on Aperiodic Crystals ICQ10 in Zürich 2008, the
group contributed two talks (SG,UG) and two posters (MH,CH). Manuela
Heuer's and Svenja Glied's participation were supported by IUCr Young
Scientists awards, and Manuela Heuer won a prize for best student
presentation for her poster
Similar sublattices and coincidence rotations of the root lattice
A4 and its dual.
The year 2009 turned out to be a busy year, with Uwe
Grimm co-organising the exhibit
How do shapes fill space? at the
Royal Society Summer
Science Exhibition 2009 as well as the 6th International
Conference on Aperiodic Crystals Aperiodic'09 in Liverpool and a
satellite workshop in Leicester, and presenting invited talks at
meetings in Austria and France in July and October.
Aperiodic'09 was the
first major conference on aperiodic order in the UK and attracted
about 110 participants from a range of disciplines including mathematics,
physics, crystallography and materials science. The remit
of the conference covers two broad areas of research,
incommensurately modulated and composite crystals on the one hand,
and quasicrystals on the other hand, sharing the property that they
are aperiodically ordered solids.
A related EPSRC-supported workshop on Mathematical
Aspects of Aperiodic Order was held in Leicester in the week
preceding the conference, and attracted about 40 participants.
Highlights of the conference included a public lecture "Simple sets
of shapes that tile the plane but cannot ever repeat" by Roger Penrose
and a visit by Alan L. Mackay, bringing together two distinguished UK
scientists who made seminal contributions to the subject.
Two trips to Japan (ICQ11 Sapporo and RIMS workshop, Kyoto) and
Korea (KIAS workshop) were highlights in 2010. The visit to Korea was
supported by a Royal Society International Travel Grant. Uwe's talk
Some comments on a hexagonal monotile at the Korea Institute
of Advanced Study was videotaped; the recording can be viewed
here.
The year 2011 started with an Oberwolfach workshop in January. With
Marjorie Senechal, Uwe co-chaired a microsymposium What is order,
and how can one describe it (What kinds of matter diffract?) at
the International Congress of Crystallography in Madrid in August. At
the congress, Uwe was elected to the Commission on
Aperiodic Crystals of the International Union of
Crystallography. In September and October two visits to Canada are
scheduled, to attend workshops at BIRS in Banff and at the Fields
Institute in Toronto.
