This book is the second volume of a series of books on the topic of strongly interacting quantum systems. The first volume appeared in 2023, and deals with few-body quantum systems. Throughout this book, we shall refer to it simply as volume 1. This second volume is concerned with strongly interacting quantum many-body systems. There are a vast amount of basic and advanced textbooks available on quantum many-body physics. Almost any preface deals with this issue, and answers it with the question ‘another book on many-body physics?’. The answer, always affirmative, goes on to justify the need for yet another book on the topic. We shall do no such thing. This is not a book on many-body physics, but on the use of few-body machinery to tackle non-perturbative physics in many-body systems. It often turns out that few-particle solutions are sufficient to explain a plethora of many-body phenomenology. Sometimes, quantitative predictions can be made, while other times relations or qualitative—but highly non-perturbative—estimates are made. This field is, admittedly, quite niche, and we do not know of any other textbook on the subject. It can be difficult at times, and so we have included as many details in our derivations and calculations as possible, following the same philosophy as in volume 1. Although not always necessary, we recommend the reader to carefully study volume 1 before attempting to read this book. We have chosen a number of topics that we think are most representative of the approach we follow. We have left out important topics and systems that are very interesting, but we are sure that these pages will help the reader to develop this field further, should they be interested in doing so. We thank our Editor at IOP Publishing, Phoebe Hooper, for her help and persistence. We could neither have started nor finished this project without the support of many colleagues with whom we have discussed and collaborated in this and other topics, and the funding agencies that have supported our work.
