abstract = {The phase field method has emerged as the tool of choice to
simulate complex pattern formation processes in various
domains of materials sciences. For the phase field model to
faithfully reproduce the dynamics of a prescribed
free-boundary problem with transport equations in the bulk
and boundary conditions at the interfaces, the so-called
thin-interface limit should be performed. For a phase
transformation driven by diffusion, the kinetic
cross-coupling between the phase field and the diffusion
field has recently been introduced, allowing a control on
interface boundary conditions in the general case where the
diffusivity in the growing phase DS neither vanishes
(one-sided model) nor equals the one of the disappearing
phase DL (symmetric model). Here, we investigate the
capabilities of this nondiagonal phase field model in the
case of two-dimensional dendritic growth. We benchmark our
model with Green's function calculations (sharp-interface
model) for the symmetric and one-sided cases, and our
results for arbitrary DS/DL allow us to propose a
generalization of the theory by Barbieri and Langer [Phys.
Rev. A 39, 5314 (1989)] for finite anisotropy of interface
energy. We also perform simulations that evidence the
necessity of introducing the kinetic cross-coupling and of
eliminating surface diffusion. Our work opens up the way for
quantitative phase field simulations of phase
transformations with diffusion in the growing phases playing
an important role in the pattern and velocity selections.},
