Contribution
It introduces a method to manipulate interband transport via phase noise, highlighting the universality of the effect through a scaling analysis.
Findings
Phase noise can suppress or enhance interband transport.
The effect is universal across different noise parameters.
Control of atom dynamics in lattices is achieved through tailored noise.
Abstract
We show how the evolution of atoms in a tilted lattice can be changed and controlled by phase noise on the lattice. Dependent on the characteristic parameters of the noise, the interband transport can either be suppressed or enhanced, which is of interest for high precision control in experimental realization with Bose-Einstein condensates. The effect of the noise on the survival probability in the ground band is summarized in a scaling plot stressing the universality of our results.
