Descrizione

PhD student for a PhD about experimental exploration of unusual magnetic phases in rhombohedral multilayer graphene (M/F) Sintesi in italiano (traduzione automatica): Il Laboratorio di Fisica della Materia Solida (LPS) è un'unità di ricerca congiunta affiliata all'Université Paris-Saclay e al CNRS, situata a Orsay, Île-de-France. Si cerca un dottorando per esplorare fasi magnetiche insolite in grafene multilayer romboedrico. Le principali mansioni includono la conduzione di ricerche sperimentali su stati elettronici topologici e fasi correlate, con un focus su fenomeni fisici in dimensioni ridotte. È richiesta una laurea in fisica o un campo correlato. Il lavoro offre la possibilità di svolgere attività di ricerca in un ambiente collaborativo, con supporto per la formazione e benefici per i dipendenti, inclusi permessi annuali e supporto per genitori. The Laboratory of Solid State Physics (LPS) is a joint research unit (UMR 8502) of Université Paris-Saclay and the CNRS. It is affiliated with the CNRS Institute of Physics and the 28th section of the National Council of Universities (CNU). The LPS is a member of the Friedel-Jacquinot Federation, a coordination structure for physics research on the Moulon plateau in Orsay (Île-de-France). It brings together around one hundred researchers and faculty members—both experimentalists and theorists—while research activities are supported by approximately sixty engineers, technicians, and administrative staff. Each year, the laboratory hosts a large number of undergraduate and graduate students—including many PhD candidates—as well as postdoctoral researchers and visiting scientists. The laboratory covers a wider range of topics than its name suggests, aiming to address the full diversity of condensed matter physics. Research activities are organized around three main themes, each involving a similar number of scientists: • Novel electronic states of matter • Physical phenomena in reduced dimensions • Soft matter and the physics-biology interface The first theme encompasses both experimental and theoretical studies on the properties of systems characterized by strong electronic correlations; these systems exhibit remarkable properties and unconventional electronic states, such as superconductivity, magnetism, metal-insulator transitions, and more. The second theme covers activities falling under the broad umbrella of "nanosciences." Here, the focus is on fundamental properties that emerge when an object's dimensions approach certain characteristic length scales (such as coherence length, mean free path, etc.). The third theme extends the concept of "soft matter" to include biological systems. Topics range from complex systems to living tissues, and from liquid crystals to foams, as well as polymers and granular systems. These physics studies lie at the interface of physical chemistry and biology. The research will be conducted within the Mesoscopic Physics group at the Laboratory of Solid State Physics (CNRS-UMR 8502). Your work environment Remote work: remote work arrangements and allowances Annual leave and RTT (reduced working time) days: 44 days Transport: subsidized commuting costs (75% coverage) and a sustainable mobility allowance of up to €300 Support for parents: access to daycare spots, co-funded CESU vouchers and holiday vouchers, contribution to before- and after-school care costs, allowance for parents of children with disabilities, and subsidies for activities (leisure centers, holiday camps, school trips, etc.) Training: provided upon starting and throughout your career Onboarding: support during the initial settling-in period Employee benefits: subsidized health insurance, staff dining facilities, sports and leisure activities, discounted tickets, etc. -Twisted multi-layered stacks of graphene have attracted a very strong interest these last years, in part because of the very rich phase diagram at low temperature, displaying many transitions to highly correlated topological electronic states. Recently, similar correlated phases with exotic order parameters were also found in natural graphene multilayers, in portions with a rhombohedral (ABC) stacking rather than the more common bernal (ABA) stacking, see Figure below with a trilayer. One such phase is an intriguing ordered magnetic phase in which the magnetic moments are not electronic spin but loop currents. So far this unusual phase has only been indirectly revealed through transport measurements, which are insensitive to the sign of the magnetic moment with respect to the applied field. Therefore it is not known if the response is diamagnetic or ferromagnetic, an essential question to elucidate the nature of this new kind of phase transition. To determine whether this phase is diamagnetic or ferromagnetic as well as its competition with other correlated phases (sup Annuncio in inglese. Fonte: Euraxess (Commissione europea).
