Nature governs how particles interact with each other in various physical systems. However, there are instances where the nature of these interactions can be modified, leading to new phenomena and technological advancements. In a recent study published in PRX Quantum, researchers from the Université libre de Bruxelles have introduced a novel framework for manipulating and controlling the nature of nonlinearities in a wide range of physical systems, including optical devices and quantum atomic gases.
The concept of Floquet engineering, originally developed in atomic and solid-state physics, forms the basis of this groundbreaking framework. It involves subjecting a system to a time-periodic modulation to shape and design its properties. By applying this strategy, the researchers demonstrated how a carefully designed pulse sequence can generate new interaction processes between particles, resulting in highly controllable and exotic nonlinearities.
The team also extended their approach to synthetic lattice systems and showcased how drive-induced interaction processes can stabilize novel phases of matter by facilitating the emergence of magnetic fluxes.
This work has significant implications for the field of optics, where effective photon-photon interactions can be induced by the medium through which light propagates. By harnessing the power of Floquet engineering, researchers can now engineer unconventional optical nonlinearities, leading to the development of advanced photonic devices with enhanced performance and functionality.
Furthermore, this framework opens up exciting possibilities in the realm of ultracold quantum matter, where the control of nonlinearities is of paramount importance. By manipulating the nature of inter-particle interactions, scientists can explore new phases of matter and potentially unlock breakthroughs in quantum technologies.
In conclusion, this study introduces a powerful framework for modifying and controlling nonlinearities in various physical systems. By leveraging Floquet engineering, researchers can shape the nature of interactions, leading to the discovery of new phenomena and the development of advanced technologies.
