17:00 → 17:05 Introduction

17:05 → 17:25 Numerical study of the microscopic structure of jammed systems

Jamming occurs when the degrees of freedom of a system are completely blocked and is present in systems such as grains, foams, colloids, and glasses. From the perspective of phase transitions, it is of a peculiar kind because it is an out of equilibrium transition and it displays non-trivial critical scalings. Besides, the microscopic structure of jammed states exhibits a complex phenomenology that has only been elucidated recently. I will present some results about how such structure can inform us of the dynamics that occur near the jamming point and confirms important theoretical predictions.

17:35 → 17:55 Virtual micro-reality: immersive manipulation of live microscopic systems

Cells live in a physical environment whose predominant factors are no longer those of our scale and for which we lack a direct experience and consequently a deep intuition. By integrating holographic and virtual reality technologies, our instrument allows the user to be completely immersed in a dynamic virtual world which is the simultaneous replica of a real system under the microscope. Holographic microscopy allows fast 3D imaging and real-time rendering on a virtual reality headset, while hand tracking data is used to dynamically generate holographic optical traps for interactive grabbing and manipulation of microparticles arrays or living motile cells.
