Position Title  Mathematical Physics Research Assistant 
Summary  The student intern will assist mathematics, computer science and physics faculty in running molecular dynamics simulations for the temperature dependence of longitudinal wave velocities and vibrational spectra in FCC monatomic crystalline lattices. LAMMPS code and packages will be employed using C++ and MPI. 
Job Description  The intern will extend her 2010 research in computational solidstate physics. The classical issues from mathematical physics are temperature dependence of longitudinal wave velocities and vibrational spectra in monatomic crystalline lattices. Her 2010 proofofconcept simulations tested standard theory of anharmonic oscillations, using Berkeley Madonna for 1dimensional lattices with harmonic, piecewise harmonic and LJ potentials. For this 201112 internship, the student will extend that research to 2dimensional hexagonal and FCC lattices using LAMMPS (C++ and MPI) available on OSC's Glenn Cluster. Pre and postprocessing will use the Pizza.py toolkit written in Python. The intern's longrange goals are to become a researcher in electrical engineering or materials science so as to develop more energyefficient transportation technologies. While the project employs classical molecular dynamics with the primary goal of advancing research in mathematical physics, the purpose of this internship is broader. Through exposure to parallel algorithms and foundational concepts of solidstate physics the intern would gain the basis for researching a wide range of scientific applicationsfrom theoretical physics (effective metrics) to materials science & engineering (defect dynamics, thermal degradation, phonons and superconductivity).
