Novel Directions in Frustrated and Critical Magnetism

Jul 14, 2014, 9:00 AM → Aug 8, 2014, 6:00 PM Europe/Stockholm

132:028 (Nordita, Stockholm)

Anders Sandvik (Boston University), Eddy Ardonne (Stockholm University), Stephen Powell (Nordita)

Venue

Nordita, Stockholm, Sweden

Scope

In a frustrated system, competition between interactions hinders the tendency towards forming an ordered state, allowing for the emergence of new physical phenomena. This programme will bring together experts in the field of frustrated and critical magnetism as well as younger researchers, to discuss recent developments, explore connections between different areas of research, and generate new ideas.

Topics of interest include:

• Quantum spin liquids in theory and experiment
• Spin ice, classical and quantum: monopoles, dynamics, and topological order
• Criticality in magnetic and constrained systems
• Frustration in context: multiferroicity, charge degrees of freedom, and disorder

The programme will run for four weeks, from 14 July to 8 August (immediately following HFM 2014). We plan to have one or two talks per day with plenty of time for discussions in a relaxed atmosphere.

Schedule

The preliminary schedule of talks and list of participants are now available.

Accommodation

Participants who have requested accommodation will be housed at three locations in Stockholm:

• BizApartment Gärdet
• Matsällskapet
• Wallquistska Guesthouse

Please see the links for information about travel to and from the accommodation.
