Light-induced gauge fields for ultracold atoms This review discusses the creation of gauge fields in ultracold atomic systems, which can mimic the behavior of electrons in magnetic fields or non-Abelian gauge fields. These fields are generated by coupling atoms to laser fields, creating effective gauge potentials. The review covers both Abelian and non-Abelian gauge potentials, their implications in quantum simulation, and experimental techniques for their realization. Gauge fields are central to our understanding of physics, from high-energy scales to gravity. In ultracold atomic systems, gauge fields can be engineered using laser-induced potentials, allowing for the study of quantum phenomena. These fields can be static or dynamical, with dynamical fields being important for simulating interacting gauge theories. The review discusses various techniques for creating gauge potentials, including rotation, shaking, and light-matter coupling. These methods can generate artificial magnetic and electric fields, as well as non-Abelian gauge potentials through spin-orbit coupling. The review also addresses the effects of collisions in these systems and the role of gauge fields in quantum simulations. Optical lattices are used to engineer gauge fields, with techniques such as laser-assisted tunneling and shaking enabling the creation of synthetic magnetic fluxes and spin-orbit couplings. These methods allow for the study of topological states of matter and quantum simulations of condensed matter systems. The review highlights the potential of ultracold atoms for simulating complex quantum systems, including gauge theories and topological phases. It discusses the challenges in creating and stabilizing these states, as well as the potential applications in quantum computing and other areas of physics. The review concludes with a summary of current techniques for creating artificial gauge potentials and their potential applications.Light-induced gauge fields for ultracold atoms This review discusses the creation of gauge fields in ultracold atomic systems, which can mimic the behavior of electrons in magnetic fields or non-Abelian gauge fields.
