group_s.jpg

June 12–15 2017, Hanaholmen, Finland

 

Local organizer:                      Prof. Mikko Möttönen, Aalto University

International organizer:             Prof. Mikio Nakahara, Kindai University

Workshop secretary:                  Ms. Eija Järvinen (eija.jarvinen [at] aalto [dot] fi)

OVERVIEW

The aim of this workshop is to bring together the leading researchers in the field of topological defects and phenomena in quantum matter to share their results and plan future research directions. Thanks to the funding from the Academy of Finland, COMP, and JSPS, there is a special emphasis on Finnish and Japanese participants in the form of Finnish-Japanese joint seminar: Topological Structures in Quantum Matter. We expect to initiate new collaborative projects in this important field.

TOPICS IN FOCUS

  • Vortices, monopoles, knots, and skyrmions in superfluids
  • Flat-band superconductivity
  • Dilute spinor Bose–Einstein condensates

PROGRAM

The scientific program runs between June 12–15, 2017. All invited sessions last for 60 min including discussions which are encouraged to extent to the coffee breaks. Contributed talks are 15 min each including discussions.

REGISTRATION

The deadline for contributed abstracts and registration is May 15th, 2017. Register by filling and sending this form to eija.jarvinen [at] aalto [dot] fi with “Workshop registration” as the subject field. The acceptance will be notified by May 20th, 2017. There is no participation fee but the non-invited speakers are expected to pay to the conference center a daily fee of 56 € and 125 €/night for the possible single room (includes breakfast).  The daily fee includes lunches, coffee breaks, and conference facilities (not dinners). The number of participants is limited due to the relatively small meeting room used.

VENUE

The workshop will be held in the Hanaholmen conference center in the city of Espoo. It can be conveniently reached by taxi or frequent busses from downtown Helsinki. There is a direct train connection from the airport to downtown Helsinki. Use Google Maps to find the fastest (~1 h) option for public transportation. A taxi from the airport to Hanaholmen (~30 min) costs roughly 50 €. We will book the sauna, rooms, and food for the registered participants. Room availability for non-invited speakers cannot be guaranteed at Hanaholmen but we will do our best to fit in everybody.
