Query: Angle-adjustable density field formulation for modeling crystalline
  microstructures   A continuum density-field formulation with particle-scale resolution is
constructed to simultaneously incorporate the orientation dependence of
interparticle interactions and the rotational invariance of the system, a
fundamental but challenging issue in modeling structure and dynamics of a broad
range of material systems across variable scales. This generalized phase field
crystal type approach is based upon the complete expansion of particle direct
correlation functions and the concept of isotropic tensors. Through
applications to the modeling of various two- and three-dimensional crystalline
structures, our study demonstrates the capability of bond angle control in this
continuum field theory and its effects on the emergence of ordered phases, and
provides a systematic way of tunable angle analysis for crystalline
microstructures.
