Simulating Polymers: From Particles to Fields (Less Math)

This video describes how one can formulate fast, efficient and precise theoretic simulations, starting from a particle-based polymer model. Some of what I said is not super precise (this is a video overview, not a textbook) and anyone in the know can likely knitpick details. The point is to provide an intuitive understanding of field-theoretic simulations. Alternative version (more math):    • Simulating Polymers: From Particles to Fie...   MD simulations were conducted using LAMMPS, except the ubiquitin extension video – that was done using NAMD and the data were taken from an NAMD tutorial, linked below.
