We study the entanglement dynamics of two particles confined in a Razavy-type coupled double-well system that is subjected to a static electric field. Starting with an initial wave packet, time-dependent studies of entanglement measures that include concurrence and correlation function are carried out. It is observed that a static electric field offers a convenient way of the quantum control of two distinguishable particles since it can localize both the particles rendering an interesting behaviour to entanglement dynamics and consequently acts as a measure to regulate the entanglement of the two particles. Besides that, the asymmetry of quantum wells also turns out to be a means of localizing the particles and hence regulates the entanglement. The current research is of great importance to study entanglement in solid-state systems and its future applications.
