A Second Four-year Dose of Dishonest, Greedy, Cowardly, Lying, Affirmative-Action Presidency is underway, Leading from Behind. Interesting Times indeed! We wish our Republic Good Luck! Carol and I are currently working on a book due in December 2014, after which we will again bring the references and reprints on this site up-to-date. In the meantime we have endeavored to keep copies of our recent work on the Los Alamos arXiv.

Rationale for this Web Page

Books:
    "Molecular Dynamics" (Volume 258 in the Springer-Verlag series, Lecture Notes in Physics, published in 1986, and evidently out of print in 2007. I found one copy for sale at $121.17 on Amazon.com in May 2007 and decided to scan the book to make it available for interested readers.)
    "Computational Statistical Mechanics" (A comprehensive treatment of equilibrium and nonequilibrium methods and applications, published by Elsevier in 1991 as Volume 11 of the Studies in Modern Thermodynamics Series). The .pdf file here was provided through the courtesy of the Lawrence Livermore National Laboratory.
    "Time Reversibility, Computer Simulation, and Chaos" (1999, 2001) (An up-to-date description reconciling the irreversible nature of real life with the time-reversible descriptions of nonequilibrium molecular dynamics, published by World Scientific as Volume 13 of the Advanced Series in Nonlinear Dynamics, 1999, reprinted with minor corrections in 2001).
    "Time Reversibility, Computer Simulation, Algorithms, Chaos" (2012) (A revised and expanded up-to-date version of World Scientific's Volume 13 above).
    "Smooth Particle Applied Mechanics---The State of the Art" (Thorough description of the use of mesoscopic/macroscopic particles to simulate the properties of bulk matter, published by World Scientific as Volume 25 of the Advanced Series in Nonlinear Dynamics, 2006). There is a free 107 megabyte draft copy available.
    Koichiro Shida [currently at Tokyo City University] kindly translated all four of these books into Japanese, culminating with publication of the SPAM book just in time for Christmas of 2008. The second printing was finished in time for Christmas 2009.

Reviews:
    "Links Between Microscopic and Macroscopic Fluid Mechanics" (with Carol Hoover---this paper was rejected by the American Journal of Physics) [Molecular Physics 101, 1559 (2003)]
    "Mécanique de Nonéquilibre à la Californienne" [Physica A 240, 1 (1997)]
    "Nonequilibrium Molecular Dynamics; the first 25 years" [Physica A 194, 450 (1993)]

Conference Proceedings Contributions and Older Papers with Some Historical or Word-processing Interest:
    "Adiabatic Hamiltonian Deformation, Linear Response Theory, and Nonequilibrium Molecular Dynamics" (presented at Sitges, Spain at a 1980 conference in memory of Mel Green -- typed on an IBM Selectric! A Kewpie Doll drawing accompanying the manuscript was removed by the Editors.) [Springer-Verlag Lecture Notes in Physics 132]
    "Atomistic Computer Simulations" (presented at Boulder, Colorado at Howard Hanley's seminal 1982 conference on Nonlinear Fluid Phenomena -- Looks a bit like teX.) [Physica 118A, 111 (1983)]
    "Nonequilibrium Molecular Dynamics at Livermore and Los Alamos" (presented at Alghero, Sardinia at a 1991 conference celebrating Berni Alder's 65th birthday -- Microscoft Word. The Kewpie Doll Poster from the 1980 Edmonton IUPAP meeting appears here.) [NATO Advanced Science Institutes in Physics, 292B]
    "Computer Simulation of Nonequilibrium Processes" (presented at Monterey, California at the [1987 Shockwaves in Condensed Matter conference] -- B. Moran, B. L. Holian, H. A. Posch, and S. Bestiale are cited as coauthors -- prepared with an IBM Selectric). Two rejection letters from 21 April 1987 are also included. The [first] is from George Bas-Bas at Physical Review Letters (regarding "Second-Law Irreversibility of Reversible Mechanical Systems", which was submitted again on 4 May 1987 and published in [Physical Review Letters 59, 10-13 (1987)] as "Resolution of Loschmidt's Paradox: the Origin of Irreversible Behavior in Reversible Atomistic Dynamics". The latter work is exactly the same as the rejected paper but with the authors' names permuted and the title changed. The [second rejection letter](in his own hand) is from Joel Lebowitz at the Journal of Statistical Physics, regarding the paper "Reversible Mechanics and Time's Arrow", written for a volume he collated honoring Ilya Prigogine. This latter paper was next sent to Physical Review A, also on 4 May 1987, and was published in the 1 January 1988 issue of [Physical Review A 37, 252-257]. These papers illustrate some of the difficulties in publishing novel work.

Preprints:
    "Local Gram-Schmidt and Covariant Lyapunov Vectors and Exponents for Three Harmonic Oscillator Problems" (For our updated book on Time Reversibility, Computer Simulation, and Chaos) A loose translation of some of the covariant literature; with Carol Hoover. This paper was submitted and accepted on 23 June with the help of Stefano Ruffo, appearing electronically in Communications in Nonlinear Science and Numerical Simulation on 25 June 2011 and in printed form in volume 17, pages 1043-1054 in February 2012. This rapid publication is a welcome preview of the internet future.
    "Free Energy Changes, Fluctuations, and Path Probabilities" (For use in our updated book on Time Reversibility) Fluctuation Theorems and Path Probabilities; with Carol Hoover.
    "Maxwell and Cattaneo's Time-Delay Ideas Applied to Shockwaves and the Rayleigh-Bénard Problem" (Originally intended for Physics Letters A) Stability of shockwaves and convective rolls with Maxwell's (as opposed to Cattaneo's) time delay; with Francisco Uribe and Carol Hoover.
    "Three Lectures: NEMD, SPAM, and Shockwaves" (For presentation at La Herradura, Spain,in September 2010) Reviews of nonequilibrium molecular dynamics and smooth particle applied mechanics along with new results on modeling dense-fluid shockwaves and analyzing dynamical instabilities within the waves with local Lyapunov exponents and phase-space growth rates.
    "Flexible Macroscopic Models for Dense-Fluid Shockwaves: Partitioning Heat and Work; Delaying Stress and Heat Flux; Two-Temperature Thermal Relaxation" (For presentation at the 2010 Conference: Advanced Problem in Mechanics, sponsored by the Russian Academy of Science, and delivered at Saint Petersburg in July) Within shockwaves the model described here partitions heat and work separately between the longitudinal and transverse directions of the flow.
    "Time-Reversal Symmetry and Covariant Lyapunov Vectors for Simple Particle Models in and out of Equilibrium" (Physical Review E 82, 046218 (2010)) Comparison (mostly by Bosetti, Posch, and Dellago) of Gram-Schmidt and Covariant Lyapunov Exponents with Local Bounds, emphasising the fractal nature of such analyses. The physical significance of the covariant exponents and vectors is not particularly clear and needs more work.

    Biographical Information for William Graham Hoover

    I was born in Boston on 18 April (remember that famous ride of Paul Revere?) 1936 and lived later, as a boy, in Maryland, Michigan, Pennsylvania, and Washington, DC.  A chemistry teacher at Woodrow Wilson High School in Washington set me on the path that took me to Oberlin College (BA in Chemistry, 1958) and the University of Michigan (MSChem and PhD in Chemical Physics, 1961).  My thesis director at Michigan, Andrew De Rocco, sent me to Jacques Poirier (Duke University) for a postdoctoral year, after which Berni Alder attracted me to Livermore, California. Los Alamos was only number two. I spent the remainder of my research career as a physicist at the University of California's Livermore Laboratory.  I joined the Department of Applied Science (started by Edward Teller through the Davis Campus of the University and dismantled in July 2011, after his death, due to the Livermore Laboratory's growing disinterest in things academic) in 1970 and retired as Professor Emeritus in 1993.  The gradual politization and bureaucratization of the laboratory and the concurrent decline of the University of California toward a rock-bottom level of political correctness (shared at least, and perhaps exceeded, by Oberlin College and the University of Michigan) made an active retired research career much more attractive than continuing "service" to failing institutions. We completed our move to Ruby Valley, Nevada with Carol's retirement (June, 2005).We then completed our work on a book for World Scientific ("Smooth Particle Applied Mechanics---SPAM: The State of the Art") as well as two summer-2006 research projects with students at Great Basin College's HiTech Center. Now we are spending more time with the horses ( Majic, White Boy [aka Silver], and the mysterious Mr X [prosaically aka Duke] ).
