Experiment-friendly formulation of quantum backflow
نویسندگان
چکیده
Quantum backflow is usually understood as a quantum interference phenomenon where probability current of particle points in the opposite direction to particle's momentum. Here, we quantify amount for arbitrary momentum distributions, paving way towards its experimental verification. We give examples gravitational and harmonic potential, discuss procedures required demonstration using atomic gravimeters. Such an experiment would show that finding free falling above initial level could grow suitably prepared state with most downwards.

The Quantum Backflow Effect
The quantum phenomenon of probability backflow is explored. This remarkable effect arises when considering the motion of a free particle in one dimension. For a state consisting only of positive momenta, it is possible for probability to flow in the opposite direction to the particle’s momentum. A comprehensive review of the literature and some new material is presented on the backflow effect, ...
متن کاملInfluence of Backflow on Roton Quantum Evaporation
Sobnack et al. recently investigated theoretically the effect of roton backflow on the scattering of atoms, rotons, and phonons at the free surface of superfluid helium-II at T = 0K. They treated backflow semi-phenomenologically by modifying the potential in their earlier theory. This paper compares their predictions for the wave-vector dependence of roton quantum-evaporation with time-resolved...
متن کاملBackflow and Density Excitations in Quantum Fluids
By the use of the f sum rule and a separation of density excitations into single and multiple excitations, we derive exact quantum expressions for the ~ backflow contribution to the dynamic structure function S(k, co) and for the discrete single-excitation spectrum ok:. The derivation is carried out for Bose liquids, Fermi liquids, charged quantum liquids, quantum solutions, an impurity atom di...
متن کاملA new approach to quantum backflow
We derive some rigorous results concerning the backflow operator introduced by Bracken and Melloy. We show that it is linear bounded, self adjoint, and not compact. Thus the question is underlined whether the backflow constant is an eigenvalue of the backflow operator. From the position representation of the backflow operator we obtain a more efficient method to determine the backflow constant....
متن کاملInhomogeneous backflow transformations in quantum Monte Carlo calculations.
An inhomogeneous backflow transformation for many-particle wave functions is presented and applied to electrons in atoms, molecules, and solids. We report variational and diffusion quantum Monte Carlo (VMC and DMC) energies for various systems and study the computational cost of using backflow wave functions. We find that inhomogeneous backflow transformations can provide a substantial increase...
