Path Integral Monte Carlo Calculation of the Momentum Distribution of the Homogeneous Electron Gas at Finite Temperature
B. Militzer, E. L. Pollock, D. M. Ceperley
Path integral Monte Carlo (PIMC) simulations are used to calculate the momentum distribution of the homogeneous electron gas at finite temperature. This is done by calculating the…
Lowering of the Kinetic Energy in Interacting Quantum Systems
Burkhard Militzer, E. L. Pollock
Interactions never lower the ground state kinetic energy of a quantum system. However, at nonzero temperature, where the system occupies a thermal distribution of states, interacti…
Variational Density Matrix Method for Warm Condensed Matter and Application to Dense Hydrogen
Burkhard Militzer, E. L. Pollock
A new variational principle for optimizing thermal density matrices is introduced. As a first application, the variational many body density matrix is written as a determinant of o…
Volume-Collapse Transitions in the Rare Earth Metals
A. K. McMahan, C. Huscroft, R. T. Scalettar +1
We describe current experimental and theoretical understanding of the pressure-induced volume collapse transitions occurring in the early trivalent rare earth metals. General featu…
Comments on PPPM, FMM, and the Ewald Method for Large Periodic Coulombic Systems
E. L. Pollock, Jim Glosli
The three most common methods, Ewald, fast multipole (FMM) and the particle-particle particle-mesh (PPPM), used to compute the interactions in many body Coulombic systems are compa…
Inhomogeneity and Current Corrections to a Non-uniform Electronic System in Strong Magnetic Fields
A. Mazzolo, E. L. Pollock, G. Zerah
Using the polarizability of a free electron gas in a magnetic field and the Current-Density Functional Theory (CDFT) developed by Vignale and Rasolt, we derive the gradient and cur…
