Altermagnets feature vanishing net magnetization, like antiferromagnets, but exhibit time-
reversal symmetry breaking and momentum-dependent spin-split band structures. Motivated …

It is commonly believed that the energy bands of typical collinear antiferromagnets (AFs),
which have zero net magnetization, are Kramers spin-degenerate. Kramers nondegeneracy …

Pairing symmetry is a fundamental property that characterizes a superconductor. For the iron-
based high-temperature superconductors,, an s±-wave pairing symmetry has received …

We review many-body effects, their microscopic origin, as well as their impact on
thermoelectricity in correlated narrow-gap semiconductors. Members of this class—such as …

We investigate the effect of electronic correlations onto the thermoelectricity of
semiconductors and insulators. Appealing to model considerations, we study various many …

The thermoelectric power factor of the narrow-gap semiconductor FeSb 2 is greatly
enhanced in comparison to the isostructural homologues FeAs 2 and RuSb 2. Comparative …

We identify the driving mechanism of the gigantic Seebeck coefficient in FeSb 2 as the
phonon-drag effect associated with an in-gap density of states that we demonstrate to derive …

Huge negative values of both the thermopower, S=− 10 mV/K at 10 K, and the Nernst
coefficient, ν=− 550 μ V/KT at 7.5 K, are observed for FeSb 2, a narrow-gap semiconductor …

A series of binary transition metal phosphides (Ni3P, Ni12P5, Ni2P, Ni5P4, NiP, NiP2, FeP,
FeP2, FeP4, VP2, CoP) were investigated by solid state 31P MAS NMR, leading to rather …

Motivated by the peculiar behavior of FeSi and FeSb 2, we study the effect of local electronic
correlations on magnetic, transport, and optical properties in a specific type of band …
