Jiangbin Gong, Luis Morales-Molina, and Peter Hanggi
TL;DR
This paper introduces a novel method for controlling tunneling in many-boson systems through fast modulation of self-interaction strength, enabling selective tunneling of a specified number of particles, with dynamics influenced by the total number of bosons.
Contribution
It presents a new approach to coherent destruction of tunneling in many-boson systems using monochromatic modulation of self-interaction strength, allowing precise control over the number of tunneling particles.
Findings
Selective tunneling of a prescribed number of bosons achieved.
Tunneling dynamics depend on whether the total number of bosons is odd or even.
The method offers a new way to manipulate many-body quantum systems.
Abstract
A new route to coherent destruction of tunneling is established by considering a monochromatic fast modulation of the self-interaction strength of a many-boson system. The modulation can be tuned such that only an arbitrarily, a priori prescribed number of particles are allowed to tunnel. The associated tunneling dynamics is sensitive to the odd or even nature of the number of bosons.
