This book elucidates fascinating electronic phenomena of unusual Bi2-square net in layered R2O2Bi (R: rare earth) compounds using two approaches: the fabrication of epitaxial thin films and the synthesis of bulk polycrystalline powders. The Bi2-square net compounds are a promising platform to explore exotic physical properties originating from the interplay between a two-dimensional electronic state and strong spin–orbit coupling; however, there are few reports on Bi2-square net compounds due to the instability of unusual electronic configurations.

This book comprehensively presents an unconventional quantum criticality caused by valence fluctuations, which offers theoretical understanding of unconventional Fermi-liquid properties in cerium- and ytterbium-based heavy fermion metals including CeCu₂(Si,Ge)₂ and CeRhIn₅ under pressure, and quasicrystal β-YbAlB₄ and Yb₁₅Al₃₄Au₅₁.

The book begins with an introduction to fundamental concepts for heavy fermion systems, valence fluctuation, and quantum phase transition, including...

High efficiency, large scale, stationary computing systems – supercomputers and data centers – are becoming increasingly important due to the movement of data storage and processing onto remote cloud servers. This book is dedicated to a technology particularly appropriate for this application – superconductive electronics, in particular, rapid single flux quantum circuits. The primary purpose of this book is to introduce and systematize recent developments in superconductive electronics into a cohesive whole to support the further development of large scale computing systems.

This thesis addresses research on the design, fabrication, and operation of the first saddle-shaped dipole magnet for particle accelerators using a no-insulation high-temperature superconducting (HTS) magnet technology. Unlike HTS magnets with various geometries used in other applications, saddle-shaped magnets posed unresolved challenges in analysis and fabrication due to their complex shape. This thesis is the first study to systematically classify these issues and propose detailed solutions for each. Scaling up the techniques used in this research could enable the development of dipole...
