Phase diagram of Yukawa systems near the one‐component‐plasma limit revisited
(The American Institute of Physics, 1996-11-01)
Transition inverse temperatures (or Γ values) at the fluid–solid phase boundary of Yukawa systems near the one‐component‐plasma (OCP) limit have been evaluated by molecular dynamics simulations. These values are systematically ...
Laser induced impact ionization in semiconductors: A Monte Carlo study for silicon
(The American Institute of Physics, 1996-04-01)
Monte Carlo computer simulations are carried out to study impact ionization due to a sinusoidal field present in high‐power laser pulses. As an application we study the impact ionization coefficient, α, for electrons in ...
Diffusion of directed polymers in a strong random environment
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1996-05)
We consider a system of random walks or directed polymers interacting with an environment which is random in space and time. It was shown by Imbrie and Spencer that in spatial dimensions three or above the behavior is ...
A Brownian motion version of the directed polymer problem
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1996-08)
Consider a Brownian particle in three dimensions in a random environment. The environment is determined by a potential random in space and time. It is shown that at small noise the large-time behavior of the particle is ...
Measurement of the Top Quark mass at CDF
(The American Institute of Physics, 1996-02-10)
We report the measurement of the Top Quark using complete kinematic reconstruction of events with a W and 4 jets. Included in this talk are a brief description of the technique, the observed results when applied to events ...
Angular momentum and Killing potentials
(The American Institute of Physics, 1996-01)
When the Penrose–Goldberg (PG) superpotential is used to compute the angular momentum of an axial symmetry, the Killing potential Qμν(φ) for that symmetry is needed. Killing potentials used in the PG superpotential must ...
Signal averaging x‐ray streak camera with picosecond jitter
(The American Institute of Physics, 1996-03)
We have developed an averaging picosecond x‐ray streak camera using a dc‐biased photoconductive switch as a generator of a high‐voltage ramp. The streak camera is operated at a sweep speed of up to 8 ps/mm, shot‐to‐shot ...
