WebJun 1, 2024 · To work, the boomerang effect needs to have time-reversal symmetry, which means that particles must behave the same way as time advances as they rewind. By changing the timing of the first kick from the laser so that the kicking pattern was off-kilter, the researchers broke the time-reversal symmetry, and the boomerang effect … WebAug 8, 2024 · This phenomenon, dubbed the “quantum boomerang effect” (QBE), has been recently observed in an experiment simulating the quantum kicked-rotor model [Sajjad et al., Phys. Rev. X 12, 011035 (2024)].

Quantum boomerang effect: Beyond the standard Anderson model

WebMay 26, 2024 · In an Anderson localized system, a quantum particle with a nonzero initial velocity returns, on average, to its origin. This recently discovered behavior is known as … WebMar 11, 2024 · It was recently shown that wavepackets with skewed momentum distribution exhibit a boomerang-like dynamics in the Anderson model due to Anderson localization: after an initial ballistic motion, they make a U-turn and eventually come back to their starting point. In this paper, we study the robustness of the quantum boomerang effect in various … key west workforce housing ordinance
