The exploration of atomic fractional quantum Hall (FQH) states is now within reach in optical-lattice experiments. While bulk signatures have been observed in a system realizing the Hofstadter-Bose-Hubbard model in a box [Leonard et al., arXiv:2210.10919], how to access hallmark edge properties in this setting remains a central open question. We propose and analyze a realistic scheme to extract the momentum-resolved edge spectrum of atomic FQH states. Our proposal is based on subjecting the prepared FQH ground state to two interfering Laguerre-Gaussian beams, which transfer a controlled angular momentum $l$ and energy $\hbar \omega$ to the system. The resonant coupling is then detected through local density measurements, by tracking the transfer of atoms from the bulk to the edge of the FQH droplet. We benchmark our method using numerical simulations of the Hofstadter-Bose-Hubbard model, considering few bosons in the $\nu=1/2$ Laughlin ground state. These studies demonstrate that our probing scheme is well suited to extract hallmark features of FQH spectra: a chiral gapless edge branch and a gapped magneto-roton mode. These signatures are already detectable in realistic systems of two bosons, provided that the box potential is larger than the droplet. Our work paves the way for the detection of fractional statistics in cold atoms through edge signatures., Comment: 5 pages, 4 figures + Supplementary

Lo scritto intende riflettere e proporre le categorie essenziali a partire dalle quali ripensare le problematiche e le potenzialità proprie della ricerca educativa con particolare riferimento alle categorie che ruotano intorno all'empowerment personale e sociale. Tutto ciò con particolare riferimento ai cambiamenti legati alle variabili dettate dalla società contemporanea in cui, tra l'altro, sempre aperto è il dibattito sulla logica, la sintassi e la teleologia della ricerca educativa .

Women’s thoughts, roles and practices: time, work, generativity In an attempt to represent and give back a possible represen-tation (among many possible ones) of feminine adultness, as it is comes into being in the Italian sociocultural context, this contri-bution intends to analyze three specific categories, such as time, work, generativity. The intention is to investigate and to read, from a pedagogical point of view, the different roles and caring practices enacted everyday by women, both in the public and private sphere, or situations. These three categories – including generativity considered in its different meanings and semantic implications – have been se-lected, because they are representative of the complexity of living, and of being adult in the contemporaneity (and this implies hav-ing different social roles). Of living and being among social, fa-miliar, working roles and freely chosen tasks, not unlinked from other roles and tasks, connected to “exogenous” requests, to so-cial representations and/or to socioeconomic demand (externally imposed, imposed from the outside). This analysis shows how gender education and lifelong learn-ing are essential to focus and to facilitate a better role and task adherence (in adult people) both in relation to the meaning that they really have in everyone’s life (and therefore to personal self–realization) and to individual and social empowerment.

Lo scritto intende offrire le categorie basilari per interpretare e criticare l'identità del soggetto contemporaneo in particolare riferimento al suo essere protagonista dello sviluppo materiale e simbolico della società della conoscenza e dell’Informazione.
