Field-Theoretic Simulations in Soft Matter and Quantum Fluids

Field-theoretic simulations are a novel molecular computer simulation method that samples and evolves continuous fields, enabling the analysis of complex systems such as high molecular weight polymers, self-assembling fluids, and quantum fluids. They can be converted to equilibrium field theory models with a molecular basis and are efficient, accurate, and scalable on modern computer hardware. Non-equilibrium systems and advanced techniques are also discussed.

This comprehensive monograph offers a thorough introduction to field-theoretic simulations in classical soft matter and Bose quantum fluids. It represents a novel approach in molecular computer simulation, wherein continuous fields, rather than particle coordinates, are sampled and evolved. Field-theoretic simulations possess the capability to analyze the properties of complex systems that pose challenges for traditional simulation techniques, such as dense phases of high molecular weight polymers, self-assembling fluids, and quantum fluids at finite temperature. The monograph delves into analytical methods for transforming classical and quantum many-body problems into equilibrium field theory models with a molecular foundation. Furthermore, it outlines numerical techniques that enable efficient, accurate, and scalable simulations of these models on modern computer hardware, including graphics processing units (GPUs). The book also explores extensions to non-equilibrium systems, introducing advanced field-theoretic simulation techniques such as free energy estimation, alternative ensembles, coarse-graining, and variable cell methods. By providing a comprehensive overview of field-theoretic simulations, this monograph serves as a valuable resource for researchers and practitioners in the fields of soft matter physics, quantum mechanics, and computer science.
