Volume Fluctuations

Recent preliminary results on multiplicity fluctuations in p+p, Be+Be and Ar+Sc collisions from the NA61/SHINE collaboration are presented. The scaled variance of charged hadron multiplicity changes little when going from p+p to Be+Be collisions and drops dramatically from Be+Be to Ar+Sc interactions. The centrality selection procedure and the influence of volume fluctuations are discussed. Comparisons with the EPOS event generator are shown.

This contribution presents a selection of recent results on meson production from the NA61/SHINE experiment. The results include spectra of ø mesons in p + p collisions at 40, 80 and 158 GeV/c beam momenta, as well as π±, K±, ρ0, ω and K*0 mesons in π− + C collisions at 158 GeV/c and 350 GeV/c. They are compared with predictions of several models. A spectacular failure of considered models is observed for ø, ρ0 and K*0 production. Also a very peculiar system size dependence of the longitudinal evolution of ø production, contrasting with all other measured hadrons, is shown. Finally, preliminary results on spectator-induced electromagnetic effects in π± production in Ar + Sc at 150A GeV/c are presented, bringing information on space-time evolution of the hot and dense matter created in the collision.

Manipulation of the charge of the dielectric interface between two bulk liquids not only enables the adjustment of the interfacial tension, but also controls the storage capacity of ions in the ionic double layers adjacent to each side of the interface.

Hubbard Models

We present stochastic diagonalization results for the ground-state energy and the largest eigenvalue of the two-fermion density matrix of the BCS reduced Hamiltonian, the Hubbard model, and the Hubbard model with correlated hopping. The system-size dependence of this eigenvalue is used to study the existence of Off-Diagonal Long-Range Order in these models. We show that the model with correlated hopping and repulsive on-site interaction can exhibit Off-Diagonal Long-Range Order. Analytical results for some special limiting cases indicate that Off-Diagonal Long-Range Order not always implies superconductivity.
