Control of tunneling in an atomtronic switching device

摘要: The precise control of quantum systems will play a major role in the realization atomtronic devices. As case electronic systems, desirable property is ability to implement switching. Here we show how switching model dipolar bosons confined three coupled wells. describes interactions between bosons, tunneling adjacent wells, and effect an external field. We conduct study dynamics system probe conditions under which behavior can occur. analysis considers both integrable non-integrable regimes within model. Through variation field, demonstrate be controlled various “switched-on” “switched-off” configurations. Atomtronics uses ultracold atoms construct analogues devices such as diodes transistors. authors report device by controlling boson tunnelling triple well system.
