FUNCTIONAL MATERIALS

New frontiers in topological matters

The symposium offers a venue for the discussion of the latest developments and research efforts related to topological materials and their functionality. There are three main goals the symposium want to achieve: (i) showcase the newest results and controversies in the field, both in theory and experiment (ii) connect research directions in topological matter across various fields (iii) give hints at the future directions and emerging topics in this always expanding and exotic field.

Scope:

Topology has found a route from purely mathematical concepts to physics applications. The discovery of the quantum spin Hall effect and topological insulators more than a decade ago has revolutionized modern condensed matter physics. Today, the field of topological states of matter is one of the most active and fruitful research areas, and intense efforts have been devoted to the exploration of new phases of matter. This goal is driven not only by the prediction of fundamentally new physical phenomena, but also by the potential technological applications of such materials. Among such applications are topological quantum computation, information processing with very low dissipation, new devices, developments of new codes, new material engineering.

The field is expanding at the speed of light. New materials, even atomically thin ones, have been proposed to be topological insulators. Moreover, classification of topological phases is extended and candidates of higher order topological materials have been found. At the same time, the study of the interaction between superconductivity and topological materials, such as quantum anomalous Hall insulators and Weyl semimetals, is yielding new and interesting results. Many new systems have been proposed to host Majorana zero energy modes for quantum computation. During this symposium, we would like to bring in pioneers in the field of topological and correlated materials to share their latest findings and insights with the participants. Topological concepts are now widely used in many branches of physics, not only limited to condensed matter systems but also in ultracold atomic systems, photonic materials and trapped ions. We hope that this symposium will inspire new ideas through communication between different fields. Moreover, this will foster collaborations among researchers and provide an opportunity for young researchers to learn from leaders in the field.

Hot topics to be covered by the symposium:

  • Topological crystalline insulators
  • Topological superconductivity
  • Majorana fermions and topological quantum computing
  • Quantum anomalous Hall insulators
  • Weyl and Dirac semimetals
  • Higher order topological insulators and superconductors
  • Topological insulating magnets
  • Interplay of superconductivity and topological materials
  • Floquet and interacting topological systems
  • Topology in mesoscopic systems
  • Dissipative topological matter
