We study the interaction of dark solitons with a localized impurity in Bose-Einstein condensates.
We apply the soliton perturbation theory developed earlier in optics for describing the …

NA61/SHINE (SPS Heavy Ion and Neutrino Experiment) is a multi-purpose experimental
facility to study hadron production in hadron-proton, hadron-nucleus and nucleus-nucleus …

… The ToF-F detection efficiency was estimated by requiring that a track traversing the ToF-F
wall generates a hit in the ToF-F. The ToF-F inefficiency is due also to double hits and readout …

Spectra of positively charged kaons in p+ C interactions at 31 GeV/c were measured with the
NA61/SHINE spectrometer at the CERN SPS. The analysis is based on the full set of data …

… law f is chaotic on a compact invariant set S (eg the attractor of a dissipative system, see
below), if f is transitive on S (ie there exists a point with a trajectory dense in S) and if f shows …

… In order to find the unstable points of the periodic cycles of period i we simply have to replace
f in Eq. (2) by its ith iterate f i . Following the above procedure it turns out that the number of …

… From this definition it is clear that F is a density per site corresponding to the order parameter
F and it is expected to have the characteristic fluctuations of F. Now we produce a ”time” …

We investigate the electronic structure of the helium atom in a magnetic field between B= 0
and. The atom is treated as a nonrelativistic system with two interacting electrons and a fixed …

We show that critical opalescence, a clear signature of second-order phase transition in
conventional matter, manifests itself as critical intermittency in QCD matter produced in …
