Generalized Berry Conjecture and mode correlations in chaotic plates

, 2004
We consider a modification of the Berry Conjecture for eigenmode statistics in wave-bearing systems. The eigenmode correlator is conjectured to be proportional to the imaginary part of the Green's function.

Energy Spectrum Evolution of a Diffuse Field in Elastic Body Caused by Weak Nonlinearity

, 2004
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 convolution of the linear energy at two frequencies.

Što je atomska orbitala? [PDF]

Kemija u Industriji, 2018
Pojam atomske, odnosno molekulske orbitale osnovni je pojam kemije koji svoje potpuno tumačenje dobiva tek u okviru kvantne fizike. Atomska orbitala zapravo je pojam izveden iz pojma valne funkcije ili vektora stanja, koji su stoga prvi objašnjeni, uz ...

Observation of Stückelberg oscillations in accelerated optical lattices [PDF]

Physical Review A, 2010
We report the experimental observation of St ckelberg oscillations of matter waves in optical lattices. Extending previous work on Landau-Zener tunneling of Bose-Einstein condensates in optical lattices, we study the effects of the accumulated phase between two successive crossings of the Brillouin zone edge. Our results agree well with a simple model
