The rare event route to programmable time crystals

Time crystals are many-body systems that spontaneously break time-translation symmetry, and thus exhibit long-range spatiotemporal order and robust periodic motion. Recent results have demonstrated how to build time-crystal phases in driven diffusive fluids, based on a particular class of symmetry-breaking dynamical phase transitions present in their rare event statistics. A main tool in this idea is the application of an external packing field coupled to density fluctuations, that triggers an instability to a time-crystal phase. In this seminar we will explore the connection between time crystals, rare events and dynamical phase transitions. We will also describe how to exploit this packing-field mechanism to engineer and control on demand programmable continuous time crystals characterized by an arbitrary number of rotating condensates, which can be further enhanced with higher-order modes. We will elucidate the underlying critical point, as well as general properties of the traveling condensates, illustrating our findings in various paradigmatic driven diffusive systems. Overall, these results demonstrate the versatility and broad possibilities of this promising route to time crystals.
Pablo Hurtado is Full Professor of Condensed Matter Physics at the University of Granada. He completed his PhD at the University of Granada in 2003, followed by postdoctoral appointments as a FULBRIGHT/MEC fellow at Boston University and as an EU Marie Curie/TMR researcher at the Charles Coulomb Laboratory in Montpellier. He has been at the University of Granada since 2006, becoming Associate Professor in 2012 and Full Professor in 2023. His research lies in nonequilibrium statistical physics, with a focus on emergent phenomena in driven interacting systems. His work spans topics such as macroscopic fluctuation theory, large deviations and current fluctuations, dynamical phase transitions, anomalous transport and hydrodynamics, time crystals, and quantum thermodynamics. His research sits at the interface of statistical physics, condensed matter theory, fluid dynamics, and computational physics. He has published around 70 papers in leading journals, including some influential review articles. He has supervised multiple postdoctoral researchers and PhD students, and delivered invited talks at leading institutions such as Harvard, Princeton, Berkeley, Cambridge, and CEA-Saclay. He has also co-organized a number of international conferences, most notably the Granada Seminar on Computational and Statistical Physics for the past 25 years.
