Multiwavelength studies of MHD waves in the solar chromosphere: An overview of recent results

The chromosphere is a thin layer of the solar atmosphere that bridges the relatively cool photosphere and the intensely heated transition region and corona. Compressible and incompressible waves propagating through the chromosphere can supply significant amounts of energy to the interface region and corona. In recent years an abundance of high-resolution observations from state-of-the-art facilities have provided new and exciting ways of disentangling the characteristics of oscillatory phenomena propagating through the dynamic chromosphere. Coupled with rapid advancements in magnetohydrodynamic wave theory, we are now in an ideal position to thoroughly investigate the role waves play in supplying energy to sustain chromospheric and coronal heating. Here, we review the recent progress made in characterising, categorising and interpreting oscillations manifesting in the solar chromosphere, with an impetus placed on their intrinsic energetics.Comment: 48 pages, 25 figures, accepted into Space Science Review

Type II InAs/GaAsSb quantum dots: Highly tunable exciton geometry and topology

External control over the electron and hole wavefunctions geometry and topology is investigated in a p-i-n diode embedding a dot-in-a-well InAs/GaAsSb quantum structure with type II band alignment. We find highly tunable exciton dipole moments and largely decoupled exciton recombination and ionization dynamics. We also predicted a bias regime where the hole wavefunction topology changes continuously from quantum dot-like to quantum ring-like as a function of the external bias. All these properties have great potential in advanced electro-optical applications and in the investigation of fundamental spin-orbit phenomena

Status of the NUMEN Construction

The NUMEN (NUclear Matrix Elements for Neutrinoless double beta decay) project at INFN-Laboratori Nazionali del Sud aims to extract quantitative information on the Nuclear Matrix Elements relevant to neutrinoless double beta decay, a key process for determining whether the neutrino is a Majorana or Dirac particle and for establishing its effective mass. This objective will be pursued by measuring the cross sections of double charge exchange reactions induced by intense heavy-ion beams on selected isotopes that are candidates for neutrinoless double beta decay. The need to measure extremely low cross sections with high statistical significance has driven a major upgrade of the entire INFN-LNS infrastructure, enabling the production of heavy-ion beams with intensities up to 1013 pps at the position of the experimental target. Additionally, significant enhancements are being made to the focal plane detectors of the existing MAGNEX spectrometer. A new target system and advanced detectors are under development to track and identify heavy ions at an expected rate of 5×106 Hz at full beam intensity, while also allowing γ-ray detection. This contribution provides an overview of the current status of the NUMEN project, highlighting recent developments and characterization campaigns for nuclear targets and detector systems
