摘要: Abstract Devices based on ultracold atoms moving in an accelerating optical lattice or double-well potential are a promising tool for precise measurements of fundamental physical constants as well the construction sensors. Here, we carefully analyze model couple BECs separated by barrier accelerated field and show how observable quantities, mainly period beating motion phase-shift, related to parameters energy initial state.
