This manuscript presents an algorithm implemented in a commercial computational fluid dynamics (CFD) code for parallelisation of the Lagrangian particle tracking model in a mixed Eulerian–Lagrangian CFD algorithm. The algorithm is based on the domain decomposition parallelisation strategy and asynchronous message passing protocol. The methodology i...
The present work treats the role of ghost fields in the renormalization
procedure of the Lagrangian perturbative formalism of the t-J model. We
show that by introducing proper ghost field variables, the propagators
and vertices can be renormalized to each order. In particular, the
renormalized ferromagnetic magnon propagator coming from our previou...
