The nature of the Fermi surface observed in the recently discovered family of unconventional
insulators starting with SmB6 is a subject of intense inquiry. Here we shed light on this …

To finally resolve the controversial issue of whether or not the electronic structure of YbB 6 is
nontrivially topological, we have made a combined study using angle-resolved …

Dirac semimetals show nontrivial physical properties and can host exotic quantum states
like Weyl semimetals and topological insulators under suitable external conditions. Here, by …

Ambient-pressure room-temperature superconductivity is one ultimate goal of science, for it
will bring worldwide revolutionary changes in all kinds of technology. Several room …

Antiferromagnetic materials, whose time-reversal symmetry is broken, can be classified into
the Z 2 topology if they respect some specific symmetry. Since the theoretical proposal …

SmB6 has drawn much attention in recent times due to the discovery of anomalies in its
ground state properties as well as prediction of topologically protected gapless surface …

Using first-principles calculations, we predict a Chern insulating phase in thin films of the
ferromagnetic semimetal GdN. In contrast to previously proposed Chern insulator …

Heavy-fermion family exhibits fascinating and often puzzling properties due to the presence
of open-shell f ions and the complexity of the associated charge, orbital, and spin degrees of …

Kondo insulator Sm B 6 has attracted attention because it can realize new topological
phenomena driven by the interplay between strong correlation effect and topology …

We report the study of transport and magnetic properties of the YbB6–δsingle crystals grown
by inductive zone melting. A strong disparity in the low temperature resistivity, Seebeck and …
