In this work, quantum control of nanoparticles will be considered at low temperature. It would be interesting for researchers to take the well known nanoparticles at the scale of 10-9m as they are at the proper low temperature. It is desired to create Bose-Einstein-Condensates (BEC) with the nanoparticle. In our former study of controlling nanoparticle, the density function theory (DFT) described by time-dependent schrödinger equation had been utilized to apply control theory to nanoparticles at matter surface. In the framework of Thomas-Fermi (TF) model, the nanoparticle governed quantum system had been considered in the complex Hilbert space. In this inverstigation, the factor of temperature will be taken account into time-dependent schrödinger equation. First, physically, a lot of questions will be arising in here for the purpose of phenomena of low termperature control. Such as, whether BEC can be created using nanoparticle? what can the nanoparticles do at low temperature? which difference have for the nanoparticles BEC than other size particles? how control would be proceeded for nanoparticles at magnetic-electric field? Second, theoretically, the application of control theory to nanoparticles BEC in the framework of varitional theory. Then get the first hand theortic results to do nanoparticles control at low temperature. Reivew current contributed work and literatures, the survey of control Bose-Einstein-Condenstate had been occured at amount of areas and got significant milestone results as the atomic particles (e.g. 87Rb, 7Li, 23Na,52Cr, 39K) cooling to a temperature below of BEC threholds. Indeed, the behavior of nanoparticles at room temperature had also been considered and been created to Carbon (C) nanotube, nanowire, nanomotor, nanorod as advanced materials. The focus point in here is nanoparticles at low temperature, what it is happend? the exciting and attractive consclusion will be hoped in this paper. As a kind of prediction, this theoretical research for control of nanoparticles would be quite interesting, control theory could be applied to these sort of nanoparticle perfectly. Without lost of generality, nanoparticles composed BEC will be much more useful and can be quickly utilized to real society in the world. It is good to connect this research to chemical and physical labortory, and to do further interdisciplinary work concering the control of quantum system.
