Dynamics of dark-soliton formation in a polariton quantum fluid

Polariton fluids have revealed huge potentialities in order to investigate the properties of bosonic fluids at the quantum scale. Among those properties, the opportunity to create dark as well as bright solitons has been demonstrated recently. In the present experiments, we image the formation dynamics of oblique dark solitons. They nucleate in the wake of an engineered attractive potential tha...

Quantum-like gravity waves and vortices in a classical fluid

We have recently proposed a new general concept of macroscopic quantum-type experiment. It amounts to transform a classical fluid into a quantum-type fluid by the application of a quantum-like potential, either directly in a stationary configuration, or through a retro-active loop to simulate the time evolution. In this framework, the amplitude of the quantum potential depends on a macroscopic ...

Quantum Superluminal Communications Michai

Quantum nonlocality arising from entasgled states is the most fundamental and the most mysterious phenomenon in quantum mechanics, and it is in the core of quantum information theory. Fomally quantum nonlocality follows from the SchrMinger equation; however, its physical meaning is still unclear despite successful experimental confirmation,"] and applications to teleportation, cryptography and...
