Numerical Simulation of a Macro-quantum Experiment: Oscillating Wave Packet

We perform numerical simulations of a new proposal of laboratory experiment that would allow the transformation of a classical °uid into a quantum-type (super)°uid through the application of a generalized quantum potential. This quantum potential is simulated by using a real time retroactive loop involving a measurement of density, a calculation of the potential in function of the measured density, then an application of the calculated potential through a classical force. This general experimental concept is exempli ̄ed here by the case of a nonspreading oscillating wave packet in a harmonic oscillator potential. We ̄nd signatures of a quantum-like behavior which are stable against various perturbations. Finally, the feasability of a realization of this concept in an actual plasma experiment is analyzed.
