Quasicrystals: pattern formation and aperiodic order

ICMS, 15 South College Street, Edinburgh, EH8 9AA
4-8 June 2018

Organisers

Andrew Archer, University of Lougborough
Uwe Grimm, Open University
Alastair Rucklidge and Priya Subramanian both University of Leeds

The central aim of this workshop is to bring together four different research communities to understanding quasicrystals (QCs) and aperiodic order: (i) QCs in materials science, (ii) QCs in soft matter, (iii) QCs in partial differential equations (PDEs) and (iv) QCs in aperiodic tilings. An improved level of engagement and understanding between researchers in these areas will bring great benefits to our understanding of QCs.

The workshop will capitalise on recent progress by giving leading and upcoming researchers a forum to discuss how different approaches can be most effectively combined to tackle and solve the big open problems in the field. Hosting this workshop will allow the UK community to take a lead role in the efforts to achieve this goal.

Further objectives of the workshop are to:

  • Share current state of knowledge from the communities working in different but related fields
  • Share open problems and discuss what approaches might be transferable to attack these
  • Initiate joint projects between participants
  • Convene a subgroup of participants to prepare a joint survey article (or a collection of articles) presenting the state of the art
  • Discuss and plan potential public engagement activities
  • Discuss and plan further workshops and meetings to build on outcome of the workshop
  • Discuss funding opportunities for joint research projects.

Photographs of the workshop group and the public lecture and exhibition are now available on the ICMS Flickr account.

 

Arrangements

ENQUIRIES

Administrative enquiries regarding practical arrangements in Edinburgh should be emailed to: audrey (dot) mccrorie@icms.org.uk.

Please note that this workshop will commence at 09.00 on Monday 4 June and close around lunchtime on Friday 8 June 2018.

PARTICIPATION

Participation is by invitation only. Invitations were issued by ICMS in January 2018. 

REGISTRATION FEE

A registration fee of 100 GBP is payable by all. Further details about payment will be emailed to participants. 

VENUE

The workshop will be held at ICMS, 15 South College Street, Edinburgh, EH8 9AA.

UK VISAS

If you are travelling from overseas you may require an entry visa. A European visa does not guarantee entry to the UK. Please use this link to the UK Visas site to find out if you need a visa and if so how to apply for one.

TRAVEL

Please note that it is your responsibility to have adequate travel insurance to cover medical and other emergencies (volcanic ash disruptions) that may occur on your trip.

A taxi directly from the airport will cost approximately 20.00 to 25.00 GBP to the city centre for a one-way journey.    There is also a bus service direct from the airport to the city centre which will cost 4.50 GBP single or 7.50 GBP return - the Airlink 100.  This is a frequent service (every 10 minutes during peak times) and will bring you close to Waverley Railway Station, only a short walk to the accommodation and the workshop venue.

Lothian buses charge £1.70 for a single, £4.00 for a day ticket. Please note that the exact fare is required and no change is given.

If travelling by train, please note that Edinburgh has several railway stations - Waverley Railway Station being the main station and closest to the workshop venue at 15 South College Street.  If you alight at Edinburgh Waverley, the workshop venue is an easy 10 minute walk over North and South Bridge.

TALKS AND AUDIO/VISUAL EQUIPMENT

All talks will be held in the Newhaven Lecture Theatre.  The lecture theatre has a built in computer, data projector, and visualiser/document camera.  In addition, there are two blackboards.  The projector and one board may be used simultaneously.  We advise Speakers that, where possible, you bring your talk on a memory stick/USB to put onto our computer in advance of your session - either at the start of the day or during coffee/lunch breaks.   ICMS staff can help with this.   It is possible for you to use your own laptops but it is then your own responsibility to ensure that resolutions are changed on the laptops if necessary (ICMS will not change the resolution on our equipment).   If you use a Mac we expect you to bring your own adaptor.

POSTER SESSION

The poster session and informal wine reception will be on Monday 4 June, 17.00-18.30.   Posters may be of any size, portrait or landscape.   Please give your poster to ICMS staff when you arrive at Registration and it will be displayed for you in time for the poster session.

CATERING

Refreshments will be served during the coffee breaks in the Programme.  It is anticipated that lunch will be provided Monday, Tuesday and Thursday.  As Wednesday is a free afternoon, lunch is not provided and participants are free to visit the many cafés and restaurants nearby. The workshop will close at lunchtime on Friday to enable travel that day - again no lunch is provided.  There will be a wine reception one evening and a workshop dinner which will take place in Blonde Restaurant, 75 St Leonard's Street, Edinburgh, 19.00, on Thursday 7 June 2018.  There is no charge to workshop participants for attendance at the dinner. 

PUBLIC LECTURE AND EXHIBITION

On Tuesday 5 June, there will be an Art and Public Lecture evening as part of the workshop. Three artists will join the workshop to discuss their work and how it relates to the themes of the workshop.  This will be followed by a public lecture by Roger Penrose.

Places have been reserved for all delegates. The remaining seats are fully booked by members of the public and there is a long waiting list. You will be asked at registration if you wish to attend so that we can release any unused seats to the waiting list.

The programme for the evening is shown below.

17.00
Doors Open to the public

17.30 -18.15   
Artists’ Talks

  • Dominic Hopkinson will talk about A Visual Interpretation of the Socolar Vertex Tiling Rules. This will describe his work as artist-in-residence at the School of Mathematics, University of Leeds. His talk will include a brief introduction to his work as a sculptor looking at how aperiodic systems function in 2 and 3 dimensional space.
  • Shelley James, has been working on a quasiperiodic tiling pattern, devised by Joan Taylor and Josh Socolar that uses a single hexagonal tile, the two versions are related by mirror symmetry. This is particularly relevant on the anniversary of Pasteur’s discovery of chiral symmetry in Tartaric Acid. There will be an opportunity for attendees to play with the tiles and build the pattern.
  • Richard Henry is an artist and teacher with particular interest in the contemplative aspects of pattern. He has lectured widely on sacred geometry and Islamic patterns, and has taught practical art courses in geometric design for the British Museum in London’s World Art and Artefacts programme.

18.15-19.00
Reception with Refreshments
This will be an opportunity to view the artists’ work.
