SIG IX (Solitons @ Work workshop)

21 June - 02 July 2021

Solitons in interactions

Lectures on topological solitons, their mathematical properties and physical applications.

As always, the aim of this informal workshop is to increase interactions (and possible future collaboration) between topological solitons oriented physicists and mathematicians. So, we are mainly focused on discussion. Therefore, we plan to have only 2 talks every day followed by rather informal discussion sessions.

This year we want to discuss problems and open questions related to dynamical aspects of topological solitons, their interactions and quantization.

Unfortunately, due to the COVID situation, the workshop will be held online. However, we do our best to keep the informal spirit of the workshop where the stress is put on the discussion rather than talks. The participation is free and open to everyone. To join the workshop and the workshop mailing list please e-mail Kasia Oles at katarzyna.slawinska [at]

This edition is organized within the framework Soliton at Work S@W .

We acknowledge financial support from the Faculty of Physics, Astronomy and Applied Computer Science of the Jagiellonian University .


We divide talks into four groups

General Ideas

  • Nick Manton (Cambridge, UK), "Wormholes and Solitons", Closing remarks
  • Luiz Ferreira (Sao Carlos, Brasil), "Self-Duality: applications of Skyrme theory to nuclear matter"


  • Kasia Oles/Tom Romanczukiewicz/Andrzej Wereszczynski (Krakow, Poland), "Collective coordinate model of kink-antikink collisions in \phi^4 theory"

    Planar Solitons

  • Bjarke Gudnason (Henan, China), "Near-BPS (baby) Skyrmions as an approach to nuclear physics"
  • Bernd Schroers (Edinburgh, UK), "The geometry of chiral skyrmion dynamics"
  • Martin Speight (Leeds, UK), "Topological Defects in Multicomponent Ginzburg Landau Theory"
  • Herbert Weigel (Stellenbosch, South Africa), "Quantum corrections to theANO vortex"


  • Josh Cork (Hannover, Germany)/Chris Halcrow/Derek Harland/Tom Winyard (Leeds, UK), "Skyrmions from Instantons"
  • Alberto Garcia Martin-Caro/Miguel Huidobro (Santiago de Compostela, Spain), Skyrme crystals - nuclear matter and neutron stars

    After each talk there will be an informal (unlimited) discussion session. There will be speacial rooms devoted for the discussion, which can be freely enterd and left: one room devoted for the topic of the talk, three tooms devoted for general topics of the workshop (kinks / planar solitons / Skyrmions), and finally, a room without any specific topic. If it will be needed we will created more rooms. A cartoon explaining how to use the breakout rooms will be sent to all participants.

    Short talks session

    There will be a session devoted for short talks (20 min.)

  • Yasha Shnir (Dubna, Russia), "Spinning Q-balls and boson stars"
  • Carlos Naya (Stockholm, Sweden), "Skyrmion tubes in liquid crystals"
  • Andy Royston (Penn State U., US), "Simulating magnetic monopole-defect dynamics"
  • Andreas Fring (London, UK), "Degenerate and nonlocal soliton solutions from PT-symmetry"
  • Paul Leask (Leeds, UK), "The baby Skyrme crystal"
