High-energy-density matter is now routinely produced at large laser facilities. Producing fusion energy at such facilities challenges our ability to model collisional plasma processes that transport energy among the plasma species and across spatial scales. While the most accurate computational method for describing collisional processes is molecular dynamics, there are numerous challenges associated with using molecular dynamics to model very hot plasmas. However, recent advances in high performance computing have allowed us to develop methods for simulating a wide variety of processes in hot, dense plasmas. I will review these developments and describe our recent results that involve simulating fast particle stopping in dense plasmas. Using the simulation results, implications for theoretical modeling of charged-particle stopping will be given.
