The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

Topological materials have become the focus of intense research in recent years, since they
exhibit fundamentally new physical phenomena with potential applications for novel devices …

Graphene's success has shown that it is possible to create stable, single and few-atom-thick
layers of van der Waals materials, and also that these materials can exhibit fascinating and …

Nontrivial topological surface states (TSSs), which possess extraordinary carrier mobility
and are protected by the bulk symmetry, have emerged as an innovative platform to search …

Topological insulators are new states of quantum matter which cannot be adiabatically
connected to conventional insulators and semiconductors. They are characterized by a full …

Topological insulators are electronic materials that have a bulk band gap like an ordinary
insulator but have protected conducting states on their edge or surface. These states are …

The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

Certain insulators have exotic metallic states on their surfaces. These states are formed by
topological effects that also render the electrons travelling on such surfaces insensitive to …

The electron's spin is essential to the stability of matter, and control over the spin opens up
avenues for manipulating the properties of molecules and materials. The Pauli exclusion …

Topological insulators represent a new quantum state of matter which is characterized by
peculiar edge or surface states that show up due to a topological character of the bulk wave …
