متن کاملFluctuation-driven electroweak phase transition.
We examine the dynamics of the electroweak phase transition in the early Universe. For Higgs masses in the range 46 < MH < 150 GeV and top quark masses less than 200 GeV, regions of symmetric and asymmetric vacuum coexist to below the critical temperature, with thermal equilibrium between the two phases maintained by fluctuations oi both phases. We propose that the transition to the asymmetric ...
متن کاملHigher-Order Statistics for Fluctuation-Enhanced Gas-Sensing
The stochastic component of a chemical sensor signal contains valuable information that can be visualized not only by spectral analysis but also by methods of higher-order statistics (HOS). The analysis of HOS enables the extraction of non-conventional features and may lead to significant improvements in selectivity and sensitivity. We pay particular attention to the bispectrum that characteriz...
متن کاملPhase Statistics of Soliton
The characteristic function of soliton phase jitter is found analytically when the soliton is perturbed by amplifier noise. In additional to that from amplitude jitter, the nonlinear phase noise due to frequency and timing jitter is also analyzed. Because the nonlinear phase noise is not Gaussian distributed, the overall phase jitter is also non-Gaussian. For a fixed mean nonlinear phase shift,...
متن کاملStatistics of work and fluctuation theorems for microcanonical initial states
Work performed on a system in a microcanonical state by changes in a control parameter is characterized in terms of its statistics. The transition probabilities between eigenstates of the system Hamiltonians at the beginning and the end of the parameter change obey a detailed balance-like relation from which various forms of the microcanonical fluctuation theorem are obtained. As an example, su...
