About the school
This edition of the Giambiagi school will focus on recent advances in one of the most active branches of physics in recent decades: the control of macroscopic mechanical systems at the quantum limit. In recent years, various techniques have succeeded in cooling small mechanical systems of micro- and nanometric dimensions to the limit where quantum phenomena begin to be observed. Reaching the point of observing quantum effects has required the development of new materials and new techniques such as trapping and optical control, and particularly new cooling methods. These systems offer a platform for conducting experiments on topics such as quantum gravity, the quantum-classical transition, non-equilibrium thermodynamics, the Casimir effect, and low-temperature solid-state physics.

Alex Fainstein - Cavity optomechanics with polariton fluids
Cavity resonators are essential to adapt and improve interactions between photons, two-level systems, and vibrations. In this context, two important areas represent, on the one hand, systems with strong light-matter coupling, which leads to cavity exciton polaritons, and on the other hand, cavity optomechanics, which has allowed the demonstration of dynamical backaction phenomena in the interaction between light and vibrations. In the field of polaritonics, Bose-Einstein condensates of these strongly interacting quasi-particles (“light fluids”) have been demonstrated. In cavity optomechanics some milestones represent laser cooling to the quantum limit, and the stimulated emission of hypersound. Traditionally, these two areas have had little overlap, although their cross-fertilization represents a challenge that promises paradigmatic shifts in the control and applications of light-matter interactions. In these introductory talks I will describe what these fields are and how, on the one hand, polaritons enhance interactions between photons and phonons and, on the other hand, phonons confined in these resonators introduce novel and controllable dynamics in polaritonic Bose-Einstein condensates. Phenomena such as piezoelectric control of optical resonances at GHz frequencies, stimulated phonon emission, asynchronous locking of optical resonances, access to strong photon-exciton-phonon coupling phenomena as a path for microwave-light frequency conversion, spatio-temporal modulation to induce non-reciprocal transport, and the demonstration of continuous time crystals, are some of the consequences of combining photons, excitons, and phonons in semiconductor resonators.
