[Serge Krashakov]

Уважаемые сотрудники ИТФ,

В пятницу 15 мая в 11:30 состоится онлайн коллоквиум с докладом:

Piet Brouwer (Free University Berlin, Germany)
*Higher-order topological insulators and superconductors*

Topological insulators combine an insulating bulk with gapless states at 
their surfaces. This talk introduces "higher-order topological 
insulators", which are crystalline insulators with a gapped bulk and 
gapped crystalline boundaries, but topologically protected gapless 
states at corners or at edges of the crystal. I'll show that such 
"higher-order boundary states" are a generic boundary manifestation of 
the nontrivial bulk topology, if the bulk topology relies on a 
crystalline symmetry for its protection.
