Physics

Fernando Iemini’s work invites us to rethink our traditional perception of time and its limits. His project revolves around time crystals and their application in creating autonomous quantum clocks. In this intricate field of research, he explores how quantum laws and thermodynamics can influence the performance of these ultra-precise watches.

Fernando harmonizes the world of physics with his passions primarily through music. The guitar and piano are his first companions when he gets home from work. A connection with nature leads him to hike through mountains and waterfalls, a tradition rooted in his origins in Minas Gerais. Furthermore, Fernando is a bicycle and basketball enthusiast, a teenage passion. He began his academic career as a physics major at the Federal University of Minas Gerais, an institution that also hosted his master’s and doctorate studies in physics. The scientist also spent a year at the Scuola Normale Superiore in Pisa and two years at The Abdus Salam Center for Theoretical Physics, Trieste, Italy. Now a professor and researcher, Fernando shares his knowledge at the Universidade Federal Fluminense in Niterói.

What are the fundamental limits on our ability to measure time with the laws of quantum thermodynamics and many-body theory?
Science / Physics

What are the fundamental limits on our ability to measure time according to quantum theory and thermodynamics? Can they change our usual notion of watches? It’s time to rethink time and its fundamental limitations. Temporal crystals may hold the key to these questions. These peculiar phases of matter are characterized by a surprisingly stable and precise temporal ordering structure among their microscopic constituents, thus offering a fascinating playground for unravelling such questions.

We will explore the role of time crystals as the main working substance of an autonomous quantum clock, studying its performance in connection with quantum laws (uncertainty principles) and thermodynamics (irreversible entropic processes). The collective, many-body dynamic nature of time crystals can radically influence the operation of a quantum clock, pushing our limits to timekeeping.
