Variance of transmitted power in multichannel dissipative ergodic structures invariant under time reversal
Igor Rozhkov, Yan V. Fyodorov, Richard L. Weaver
We use random matrix theory (RMT) to study the first two moments of the wave power transmitted in time reversal invariant systems having ergodic motion. Dissipation is modeled by a…
Non-exponential Dissipation in a Lossy Elastodynamic Billiard, Comparison with Porter-Thomas and Random Matrix Predictions
Oleg I. Lobkis, Igor S. Rozhkov, Richard L. Weaver
We study the dissipation of diffuse ultrasonic energy in a reverberant body coupled to a waveguide, an analog for a mesoscopic electron in a quantum dot. A simple model predicts a…
Energy Spectrum Evolution of a Diffuse Field in Elastic Body Caused by Weak Nonlinearity
Alexei Akolzin, Richard L. Weaver
We study the evolution of diffuse elastodynamic spectral energy density under the influence of weak nonlinearity. It is shown that the rate of change of this quantity is given by a…
