Venue

Nordita, Stockholm, Sweden

Accommodation

Nordita provides a limited number of rooms in the Stockholm apartment hotel BizApartments for some participants.

Please be aware that unfortunately, scammers sometimes approach participants claiming to be able to provide accommodation and asking for credit card details. Please do not give this information to them. For successful applicants, Nordita will be in touch via email regarding accommodation. If you are in any doubt about the legitimacy of an approach, please get in contact with the organisers.

Scope

The major direction in modern condensed matter physics concerns the study of topological states of quantum matter, which show robust features due to the nontrivial global characteristics of the underlying wave functions, manifested in, for example, quantized conductance and robust gapless boundary states. Since the discovery of topological insulators about a decade ago, the field has been focused on non-interacting gapped fermionic states, classified within the so-called “ten-fold way periodic table”. However, new topological states of matter not captured within this classification have recently been theoretically proposed and experimentally discovered. These include topological crystalline insulators, Weyl semimetals, but also classical topological states in mechanical metamaterials. The proposals for realization of topological states out of equilibrium and bosonic topological phases have recently appeared. Furthermore, the new exotic fermions that go beyond the Dirac, Weyl and Majorana have been proposed. Given these developments it is clear that the study of topological matter is entering a new period where the themes going “beyond the ten-fold way” take the center stage, and will certainly be significant in the entire field of condensed matter physics in the next decade or so.

In this program, we bring together experimentalists and theorists to review the current status of this burgeoning field, identify the crucial areas where progress can be made, and foster collaborations and partnerships to vigorously pursue these goals. We shall bring together world leaders in the fields of topological materials and young researchers from the Nordic region who can learn from them.

Tentative timetable
