Thermoelectric power generation has received attention as regeneration systems for low-temperature waste heat produced by motor vehicles. Practical application of thermoelectric materials requires not only the improvement in thermoelectric performance in reference to the electronic structure but also the fabrication of durable thermoelectric modules. In the article, we review the development of the Heusler-type thermoelectric materials by pseudogap engineering and the fabrication of thermoelectric modules designed for a motorcycle.

Empirically derived Hund's rules of pre-quantum-mechanics era that predict the ordering of the energy levels possessing different spin and orbital angular momentum quantum numbers proved to be almost universally valid for atomic and molecular systems. Yet, despite the history of a long standing debate the search for various aspects of their origin persists. With a brief survey of the historical studies related to the subject, this paper explores the origin of Hund's multiplicity rule focusing on the helium-like atoms that represent an ideal system providing a direct fundamental insight into the structure of the internal part of the fully-correlated wave functions. An examination of their probability density distributions indeed reveals the existence of a region in the internal space which we refer to as conjugate Fermi hole. In this region the singlet wave function has a smaller probability density than the corresponding triplet one, in contrast to a genuine Fermi hole in which case the triplet has a smaller density than the singlet. Thanks to the presence of this conjugate Fermi hole, the singlet probability density has to migrate far away from the nucleus, rationalizing thus a broader electron density distribution and smaller nuclear attraction and electron repulsion energies of the singlet state than is the case for the corresponding triplet state.

Effects of Primordial Non-Gaussianities on the Large Scale Structure Formation(Current Topics)

Primordial non-Gaussianities, if detected in next-generation observational projects, can be a smoking gun to understand the inflationary physics. We focus on the large scale structure formation in the presence of primordial non-Gaussianities, and explain some recent theoretical progress. We show that measurements of the scale-dependent bias between the spatial distribution of galaxies and the underlying matter density field open a unique opportunity to test the Suyama-Yamaguchi inequality, which allows us to distinguish the generation mechanisms of cosmic fluctuations based on a single-component scalar field from models with multiple fields.

The charge carriers in graphene are massless Dirac fermions and exhibit a relativistic Landau-level quantization in a magnetic field. Recently, we have observed that the Landau levels of massless Dirac fermions are generated on a potassium-doped graphite surface without applying external magnetic field. The results and the origin of the Landau levels generation are described.

AdS/CFT Correspondence from Higher Spin Gauge Theories(Current Topics)

Gravity theory is a gauge theory of spin 2 field, and it can be extended to gauge theories with higher spin fields. Higher spin gauge theories can be treated as toy models of superstring theory. Recently they have attracted a lot of attention mainly due to the application to the AdS/CFT correspondence, which is an example of gravity/gauge correspondence. Here we would like to introduce higher spin gauge theories and explain how these theories are useful to understand the AdS/CFT correspondence.
