Time Crystals

This book provides the first comprehensive description of time crystals which have a repeating structure in time. It introduces the fundamental concepts behind time crystals and explores the many different branches of this new research area.

The book starts with the original idea of the time crystallization in quantum systems as introduced by Wilczek and follows the development of the field up to the present day. Both spontaneous formation of crystalline structures in time and concepts of the condensed matter physics in the time domain, ranging from Anderson localization in time to many-body systems with exotic interactions, are described. The prospect of creation of novel objects by means of time engineering is also presented.

The book assumes knowledge of quantum mechanics to the graduate level. It serves as a valuable reference with pointers to future research directions for graduate students and senior scientists alike.

Summarizes advances made in research of quantum time crystals since the idea was first proposed in 2012 by Frank Wilczek Deals with controversies surrounding time crystal concepts Ideal for researchers and graduate students wanting to understand this novel field of research

Auteur

Krzysztof Sacha is a world-renowned scientist, one of the pioneers of time crystal research and author of many prominent papers related to this topic. Among his scientific achievements belongs the prediction of the behavior of discrete time crystals in a periodically-driven many-body system. His other research themes include cold quantum gases, ionization in strong laser fields and quantum chaos. He is a Professor at Jagiellonian University in Krakow, Poland. Besides his academic work he is engaged in the popularization of science and regularly runs marathons.
