Surface Gravity of Rotating Dumbbell Shapes
Wai-Ting Lam, Marian Gidea, Fredy R Zypman
We investigate the problem of determining the shape of a rotating celestial object - e.g., a comet or an asteroid - under its own gravitational field. More specifically, we conside…
Vibration of a Cantilever Beam in Ambient Fluid
C. Metzger, J. Rodriguez, F. Zypman
Here we obtain analytical expressions for the frequency response of a cantilever beam in the presence of ambient fluid. The advantage of our approach, besides its simplicity of use…
New Supercoherent States
M. Kornbluth, F. R. Zypman
This study generalizes the supersymmetric coherent states introduced by Aragone and Zypman in 1986. The Hamiltonian of the supersymmetric quantum harmonic oscillator leads to the d…
Transitional random matrix theory nearest-neighbor spacing distributions
Fredy Zypman
This paper presents a study of the properties of a matrix model that was introduced to describe transitions between all Wigner surmises of Random Matrix theory. New results include…
Dry Friction Avalanches: Experiment and Robin Hood model
Sergey V. Buldyrev, John Ferrante, Fredy R. Zypman
This paper presents experimental evidence and theoretical models supporting that dry friction stick-slip is described by self-organized criticality. We use the data, obtained with…
Electromagnetic Waves Through Disordered Systems: Comparison Of Intensity, Transmission And Conductance
Gabriel A. Cwilich, Fredy R. Zypman
We obtain the statistics of the intensity, transmission and conductance for scalar electromagnetic waves propagating through a disordered collection of scatterers. Our results show…
