Description

---

This monograph provides an introduction to field-theoretic simulations in classical soft matter and Bose quantum fluids. The method represents a new class of molecular computer simulation in which continuous fields, rather than particle coordinates, are sampled and evolved. Field-theoretic simulations are capable of analysing the properties of systems that are challenging for traditional simulation techniques, including dense phases of high molecular weight polymers, self-assembling fluids, and quantum fluids at finite temperature.

The monograph details analytical methods for converting classical and quantum many-body problems to equilibrium field theory models with a molecular basis. Numerical methods are described that enable efficient, accurate, and scalable simulations of such models on modern computer hardware, including graphics processing units (GPUs). Extensions to non-equilibrium systems are discussed, along with an introduction to advanced field-theoretic simulation techniques including free energy estimation, alternative ensembles, coarse-graining, and variable cell methods.

Glenn H. Fredrickson, Distinguished Professor, Departments of Chemical Engineering and Materials, Materials Research Laboratory, University of California, Santa Barbara, Kris T. Delaney, Project Scientist, Materials Research Laboratory, University of California, Santa Barbara Glenn H. Fredrickson is a soft matter theorist recognized for his work on self-assembling polymers, especially block copolymers. He pioneered the "field-theoretic simulation" technique that has been widely deployed to assess the structure and phase behavior of complex, multiphase polymer systems. Fredrickson was born in Washington, D.C., and grew up in Indialantic, Florida. He graduated from the University of Florida with a B.S. degree in chemical engineering and received M.S. and Ph.D. degrees in the same discipline from Stanford University. In 1984, he joined AT&T Bell Laboratories as a Member of Technical Staff, and moved to the University of California, Santa Barbara (UCSB) in 1990 as a Professor of Chemical Engineering and Materials. Fredrickson is currently a Distinguished Professor at UCSB. He is a member of the National Academy of Sciences and the National Academy of Engineering of the USA. Kris T. Delaney is a condensed matter physicist with expertise in polymer physics, quantum many-body theory, magnetism, numerical analysis, and high-performance computing. Delaney was born in Warrington, United Kingdom, and received his M.Phys. and Ph.D. degrees in theoretical physics and physics, respectively, from the University of York. Following postdoctoral work in physics at the University of Illinois at Urbana-Champaign, he joined the Materials Research Laboratory at the University of California, Santa Barbara, in 2006, where he is currently a Project Scientist.
