Weak approximation of averaged diffusion processes
We derive expansion results in order to approximate the law of the average of the marginal of diffusion processes. The average is computed w.r.t. a general parameter that is involved in the diffusion dynamics. Our approximation is based on the use of proxys with normal distribution or log-normal distribution, so that the expansion terms are explicit. We provide non asymptotic error bounds, whic...
متن کاملEnergy-averaged weak localization in chaotic microcavities.
We have fabricated ballistic cavities from a two-dimensional GaAs electron gas in which the Fermi energy can be varied independent of cavity shape. For each cavity, we have measured the magnetoconductance G(B) of many individual members of an ensemble, with each member labeled by its Fermi energy. We find that G(B) of a single ensemble member does not always display the minimum at B50 which is ...
متن کاملAre the weak reaction channels really weak?
It has been demonstrated experimentally in many systems that the fusion barrier between two nuclei does not have a unique value but rather a weighted distribution Dfus of heights. The measurements of the barrier distributions are the long lasting project of our group. Dfus can be determined directly from fusion excitation function measurements [1]. There is also an alternative method of its det...
متن کاملDistribution of time-averaged observables for weak ergodicity breaking.
We find a general formula for the distribution of time-averaged observables for systems modeled according to the subdiffusive continuous time random walk. For Gaussian random walks coupled to a thermal bath we recover ergodicity and Boltzmann's statistics, while for the anomalous subdiffusive case a weakly nonergodic statistical mechanical framework is constructed, which is based on Lévy's gene...
متن کاملVery Weak Interference Channels
We derive a genie-based outer bound for the sum rate of discrete memoryless interference channels. We define a class of very weak interference channels and study a sub-class called the binary skewed-Z interference channel. We use the genie based outer bound to deduce the sum-capacity in a non-trivial regime of parameters for this sub-class.
