Superconducting periodic nanostructures in a magnetic field

Superconducting nanostructures in the form of square and hexagonal nets of conductors in an external magnetic field are theoretically investigated. The superconducting transition temperatures as functions of the field as well as the intricate patterns of t ...

Ground state properties of large atoms and quantum dots

We investigate the ground state properties of large atoms and quantum dots described by a d-dimensional N-body Hamiltonian of confinement ZV. In atoms, d = 3 and V is the Coulomb interaction; in dots, d = 2 and V is phenomenologically determined. We expres ...

Probing the excitation spectrum of polariton condensates

We propose a four-wave mixing experiment to probe the elementary excitation spectrum of a nonequilibrium Bose-Einstein condensate of exciton-polaritons under nonresonant pumping. Analytical calculations based on mean-field theory show that this method is a ...

Nonlinear dynamics of flute modes and self-organization phenomena in turbulent magnetized plasma

Costanza Zucca

A two-fields model that self-consistently describes the coupled, spectral dynamics of flute mode large-scale flows turbulence is presented. This model has a characteristic form of a 'predator-prey' system, in which the populations of flute mode quanta (pre ...
