“According to Road of Flowers, Mr. Kawashima’s life has been a tremendous one.”-Hakubu Shimomura, Minister of Education“I hope as many people as possible read his book to gain a better understanding of courage and to dream of a better future.”-Tadao Chiba, Denmark-Japan Social Living...

Kazuma Sato is a video game-loving shut-in-or at least he was, until a humiliating traffic accident brings his young life to an untimely end. But after his death, a beautiful girl claiming to be a goddess invites him to enter another world and gain some respectable perks in the process. But Kazuma's choice is going to have serious consequences for the goddess and the dead man alike...

Arcanletia is known for its hot springs, but perhaps even more for its devoted Axis Sect following, which is making Kazuma quite uneasy, and he's not alone. He'll need to get it together, though, because something is polluting the hot springs, and he needs all the relaxation he can get!

Now that Kazuma's charges have been cleared and his debt has been repaid, he's living in the lap of luxury. But his leisurely indulgence doesn't last long when Sena shows up with a quest for him!

After being transported to another world, Kazuma is joined by his allies Aqua the goddess, Megumin the magician, and Darkness the crusader. As they conduct more missions to fulfill quests, like purifying a lake while fending off monstrous alligators, they also progress as adventurers, receiving rewards...

After a heated argument with another adventurer, Kazuma is determined to prove that his companions aren't as wonderful as they seem. After agreeing to a one-day party swap, he finds himself traveling with a group of people he's never met! Meanwhile, Aqua, Megumin, and Darkness decide to show off to...

After returning from their trip to Japan, Kazuma and the gang find themselves in a sticky situation! The metal monstrosity known as Destroyer is fast approaching, and if they don't do something quick, the town is done for! Kazuma takes the lead, Aqua prepares to disable the barriers protecting the...

Death doesn't stop a video game-loving shut-in from going on adventures and fighting monsters!

This graduate textbook provides a unified view of quantum information theory. Clearly explaining the necessary mathematical basis, it merges key topics from both information-theoretic and quantum- mechanical viewpoints and provides  lucid explanations of the basic results. Thanks to this unified...

This book presents the basics of quantum information, e.g., foundation of quantum theory, quantum algorithms, quantum entanglement, quantum entropies, quantum coding, quantum error correction and quantum cryptography. The required knowledge is only elementary calculus and linear algebra. This way...

This brief reviews current research on magnetic skyrmions, with emphasis on formation mechanisms, observation techniques, and materials design strategies. The response of skyrmions, both static and dynamical, to various electromagnetic fields is also covered in detail. Recent progress in magnetic...

In the wake of its defeat in World War II, as Japan was forced to remake itself from “empire” to “nation” in the face of an uncertain global situation, literature and literary criticism emerged as highly contested sites. Today, this remarkable period holds rich potential for opening new dialogue...

This book explains the group representation theory for quantum theory in the language of quantum theory. As is well known, group representation theory is very strong tool for quantum theory, in particular, angular momentum, hydrogen-type Hamiltonian, spin-orbit interaction, quark model, quantum optics,...

This book is the first one addressing quantum information from the viewpoint of group symmetry. Quantum systems have a group symmetrical structure. This structure enables to handle systematically quantum information processing. However, there is no other textbook focusing on group symmetry for quantum...
