#### On the equation of state and atomic mean square displacement of crystals

(Brock University, 1989-07-09)

We have presented a Green's function method for the calculation
of the atomic mean square displacement (MSD) for an anharmonic
Hamil toni an . This method effectively sums a whole class of
anharmonic contributions to ...

#### An analysis of decoupling procedures in generating thermal Green's functions of O([lambda]â ´) by the Zubarev equation of motion method

(Brock University, 1985-07-09)

The Zubarev equation of motion method has been applied to an anharmonic
crystal of O( ,,4). All possible decoupling schemes have been interpreted in
order to determine finite temperature expressions for the one phonon ...

#### Molecular dynamics calculation of mean square displacement in alkali metals and rare gas solids and comparison with lattice dynamics

(Brock University, 1984-07-09)

Molec ul ar dynamics calculations of the mean sq ua re
displacement have been carried out for the alkali metals Na, K
and Cs and for an fcc nearest neighbour Lennard-Jones model
applicable to rare gas solids. The ...

#### Application of [Lambda] to the fourth perturbation theory in calculating the equation of state of rare gas solids and fcc metals

(Brock University, 1984-07-09)

We have calculated the thermodynamic properties of monatomic fcc
crystals from the high temperature limit of the Helmholtz free energy.
This equation of state included the static and vibrational energy
components. The ...

#### An experimental investigation of dechanneling in copper single crystals

(Brock University, 1984-07-09)

This investigation comprises a comparison of experimental and
theoretical dechanneling of MeV protons in copper single crystals.
Dechanneling results when an ion's transverse energy increases to the
value where the ion ...

#### Pressure dependence of superconductivity in amorphous Ni x Zr 100-x alloys

(Brock University, 1988-10-02)

Pressure variations of the superconducting transition
temperature Ic of a series of amorphous NixZr 1 OO-x alloys have been
studied under quasmydrostatic pressures upto 8 G Pa. For amorphous
samples having Ni-concentration ...

#### The finite bandwidth model for spin fluctuations in Pd

(Brock University, 1988-07-09)

The frequency dependence of the electron-spin fluctuation spectrum,
P(Q), is calculated in the finite bandwidth model. We find that for Pd,
which has a nearly full d-band, the magnitude, the range, and the peak
frequency ...
