- Conoscere il funzionamento di una “cassetta degli attrezzi” per concepire e realizzare in modo altamente controllato e accurato condizioni di forte correlazione nelle proprietà di carica/densità e/o di spin in liquidi quantistici, agendo su temperatura, dimensionalità, forza e range di interazione, introduzione di campi di gauge artificiali e dimensioni sintetiche;
- Conoscere le basi di selezionati metodi teorici per predire e caratterizzare lo stato fondamentale e le eccitazioni di liquidi quantistici, metterli in relazione tra loro, e classificarli in base alla loro funzionalità per specifiche tipologie di problemi. Tra i metodi teorici sviluppati sono la teoria della risposta lineare, della misura e delle funzioni di correlazione, la fluidodinamica quantistica, concetti elementari della teoria del funzionale di densità e della teoria delle funzioni di Green, ed elementi conoscitivi per mettere in relazione questi metodi teorici con selezionati metodi di
Conoscere la fenomenologia dei liquidi quantistici nelle principali piattaforme sperimentali in cui vengono correntemente ingegnerizzati e utilizzati;

Il problema viene discusso in gruppo in una apposita sessione di esame utilizzando tecniche del team-based learning (questa sessione avrà luogo alla fine del corso). Si richiede di discutere la metodologia più funzionale di trattamento, sviluppare la comprensione del problema, e comunicare i risultati, conducendo le diverse attività attraverso una suddivisione di compiti, condivisione dei risultati, e gestione autonoma del gruppo.
The assessment is performed by oral discussion of an essay on problem in the physics of quantum liquids, selected among those that have not specifically treated within the course and that uses understanding and methods developed in the course. The student is required to identify the essay subject:
- in substantial autonomy, though with the supervision of the lecturer, who will support student’s interests and curiosity
- taking care that the selected problem inlcudes a discussion of the existing phenomenology, a critical analysis of the state of the art, a methodological (theory and/or simulation) treatment, the application to one or more experimental platforms, a discussion of implications and perspectives
The individual testing is conceived to assess the development of student’s knowledge and competences in the following areas:

- Formal setting of concepts (conceptual knowledge);
- Anywhere possible, discuss the more complex problem via simple models that make use of basic physics;
- For each type of procedure, after developing the knowledge of theoretical and simulational methods for quantitative predictions by explicitly carrying out at the black/white/digital board all the needed steps of calculations, frame the abstract procedure (procedural knowledge);
- At the end of each macro-subject, interactively build up a representative conceptual map, highlighting concepts and links among them;
- The last course part is devoted to the study of cases from different platforms for quantum technologies, with the aim of practicing the folding down of conceptual and procedural knowledge towards factual knowledge.
- Elearning portal. It contains a reasoned and organized collection of detailed lecture notes, slides, conceptual maps, weblinks to selected lectures and colloquia offered by other qualified institutions (among which also ACP and KITP), besides communications related to the course and – for students’ use – the forum to discuss course topics and the final (optional) group work.

- The (optional) group work at the end of the course is performed under the supervision of the course lecturer.
- The final exam student’s essay can be prepared under the supervision of the lecturer.
- The course can be delivered in English, in accord with all the students. For the course borrowed by Materials and Technology, this is a compulsory requirement (in the event students are not akin, the course will be split in two courses).

Il corso è concepito sia per studenti che vogliano specializzarsi nella fisica teorica della materia condensata che a studenti che vogliano acquisire una cassetta degli attrezzi concettuale e metodologica per comprendere la fisica dei liquidi quantistici e il funzionamento delle tecnologie quantistiche e apprendere a concepirne di nuove. Poiché diverse sono le piattaforme sperimentali dove le tecnologie quantistiche possono essere utilmente realizzate in forme differenti con funzionalità simili, la scelta del corso è privilegiare l'ampiezza di visione concettuale e metodologica nei primi circa 2/3 del corso, dedicando l’ultima parte alle implementazioni pratiche, che pure possono essere sempre approfondite all’occorrenza.
The course is conceived for students who wish to refine their knowledge and competences on theoretical condensed-matter physics and for students who wish to acquire a conceptual and methodological toolbox to understand the physics of quantum liquids, comprehend how quantum technologies work, and learn the essentials needed to conceive them. Since quantum technologies have been developed in different experimental platforms, with different forms and similar functionalities, the course choice is to privilege a wide-open conceptual and methodological vision in the first 2/3 part of the course, and devote the last part to practical implementations, which can always be deepened whenever needed.
