 Title: Physics under extreme conditions: Magnetized atoms and hot dense plasmas Author(s): Jones, Matthew Dean Doctoral Committee Chair(s): Ceperley, David M. Department / Program: Physics Discipline: Physics Degree: Ph.D. Genre: Dissertation Subject(s): Physics, Astronomy and Astrophysics Physics, Electricity and Magnetism Physics, Condensed Matter Abstract: We discuss the physics of systems under extreme conditions, encompassing isolated atoms in very strong magnetic fields and the behavior of the electron gas near its crystallization point. For the atoms we consider a range of theoretical approaches, from mean field theory (Hartree-Fock) to an exact method using stochastic random walks (correlation function quantum Monte Carlo). We present the first calculations for magnetized lithium and carbon for field strengths ${\le}10\sp{11}$G, and construct a very accurate spectrum for magnetized helium. For the electron gas, or one component plasma (OCP), we carefully construct the phase boundary between liquid and solid at finite temperature, using a method which has no uncontrolled approximations (path integral Monte Carlo). For the first time we are able to fully treat the quantum nature of both the solid and fluid phases of the OCP.
