Synopses & Reviews
With its extreme accuracy and reasonable computational efficiency, the linearized augmented plane wave (LAPW) method has emerged as the standard by which density functional calculations for transition metal and rare-earth containing materials are judged. The second edition of Planewaves, Pseudopotentials and the LAPW Method presents an updated, thorough and self-contained exposition of the first principles methods for calculating properties of solids, in particular the "LAPW" method and will make connections between this method and planewave pseudopotential approaches. Theory is discussed, but the emphasis is on how practical implementation proceeds. In addition, the author suggests future directions for adapting the LAPW method to simulations of complex materials requiring large unit cells. He does this by elucidating the connections between the LAPW method and planewave pseudopotential approaches and by showing how Car-Parrinello type algorithms can be adapted to the LAPW method. The new edition contains new sections on developments over the last 10 years, including for example the LDA+U method, non-collinear magnetism and the APW+LO method.
Synopsis
The first edition of this book, published in 1994, provided an exposition of the LAPW method and its relationship with other electronic structure approaches, especially Car-Parrinello based planewave methods. Since publication of that book, the LAPW method has been transformed from a specialized method used mostly by researchers running their own home made versions, to a popular, widely used method, where most users run standard codes to investigate ma- terials of interest to them. This is an exciting development because it opens the door to widespread use of first principles calculations in diverse areas of condensed matter physics and materials science. The positive impact of this on scientific progress is already becoming clear. Also as a result of this trend, the great majority of researchers using the LAPW method are no longer directly in- volved in the development of LAPW codes. Nonetheless, it remains important to understand how the LAPW method works, what its limitations are, and how its parameters determine the quahty and efficiency of calculations. The scientist with an understanding of how the method works has a clear advantage. This edition is an updated and expanded treatment of the LAPW method, including descriptions of key developments in the LAPW method since 1994, such as p 1/2 local orbitals, the APW-i-LO method, LDA+U calculations and non-collinear magnetism, as well as much of the material from the first edition.
Synopsis
Planewaves, Pseudopotentials, and the LAPW Method, 2nd Edition, provides a comprehensive description of the LAPW (Linearized Augmented Plane Wave) method and its relationships with other first principles approaches for materials. The book is essential reading for practitioners of the method and for developers of electronic structure methods. This book is an updated and revised version of the previous volume. New material has been added on topics including the APW+LO method, LDA+U method, non-collinear magnetism and spin-orbit treatments. David J.
