Abstract:
Dirac fermions have attracted great interest in recent years, as seen on 
the examples of materials like graphene and topological insulators [1-2]. 
In this talk, I will discuss quantum transport in single crystals of 
(Sr,Ca)MnBi2 and similar materials [3-4]. The results demonstrate the 
existence of two dimensional Dirac fermions in bulk crystals with bismuth 
or antimony square nets and show that such states are highly relevant for 
thermoelectric performance [5,6]. References: [1] Rev. Mod. Phys. 81, 109

Rövid leírás:
Prof. Petrovic az új, intermetallikus anyagok egyik legaktívabb kutatója, 
nevéhez fűződik a CeCoIn5 felfedezése, amely a legmagasabb átmeneti 
hőmérsékletű heavy-fermion anyag.

Üdvözlettel
