Relativistic three-nucleon calculations within the Bethe-Salpeter approach
The relativistic properties of the three-nucleon system are investigated
using the Faddeev equations within the Bethe-Salpeter approach. The
nucleon-nucleon interaction is chosen in a separable form. The Gauss quadrature
method is used to calculate the integrals. The system of the integral equations
are solving by iterations method. The binding energy and the partial-wave
amplitudes (1S 0 and 3S 1) of the triton are found
Residence time statistics for blinking quantum dots and other stochastic processes
We present a study of residence time statistics for blinking quantum
dots. With numerical simulations and exact calculations we show sharp
transitions for a critical number of dots. In contrast to expectation the
fluctuations in the limit of are non-trivial. Besides quantum
dots our work describes residence time statistics in several other many
particle systems for example Brownian particles. Our work provides a
natural framework to detect non-ergodic kinetics from measurements of many
blinking chromophores, without the need to reach the single molecule limit
