Abstract

The Casimir-Lifshitz force, FC - L, has become a subject of great interest to both theoretical and applied physics communities due to its fundamental properties and potential technological implications in emerging nano-scale devices. Recent cutting-edge experiments have demonstrated the potential of quantum trapping at the nano-scale assisted by FC - L in metallic planar plates immersed in fluids through appropriate stratification of the inner dielectric media, opening up new avenues for exploring physics at the nano-scale. This review article provides an overview of the latest results in Casimir-Lifshitz based-optical resonator schemes and their potential applications in fields such as microfluidic devices, bio-nano and micro electromechanical systems (NEMS and MEMS), strong coupling, polaritonic chemistry, photo-chemistry, sensing, and metrology. The use of these optical resonators provides a versatile platform for fundamental studies and technological applications at the nano-scale, with the potential to revolutionize various fields and create new opportunities for research. Levitation, or trapping, of a flat mirror at a certain distance above another flat reflecting surface, as a result of the compensation of attractive gravitational forces by a quantum fluctuation induced repulsive force, leads to the formation of Casimir-Lifshitz optical resonators, which have opened the possibility to explore a wide range of physical phenomena at the nanoscale and a variety of technological applications. image
