@ARTICLE{Karimi, author = {Karimi, Zahra and Bagheri Harouni, Malek and }, title = {Influence of Temperature and Magnetic Field on the Quantum Speed Limit in a Coupled Quantum Dots System}, volume = {21}, number = {0}, abstract ={In the present contribution, the quantum speed limit time, as a useful parameter for investigating the quantum decoherence, is studied. The influence of temperature and magnetic field on the quantum speed limit and coherence in a coupled quantum dot system is investigated. Our finding reveals that temperature decreasing will lead to quantum speed limit decrement and consequently the decoherence rate increment. In contrast to the temperature, the magnetic field impact does not follow a same scenario, whereas the role of magnetic field depends on the initial state. Depending on the initial state, the magnetic field may possess a destructive or constructive role on the quantum speed limit or the decoherence rate. }, URL = {http://opsi.ir/article-1-774-en.html}, eprint = {http://opsi.ir/article-1-774-en.pdf}, journal = {Accepted and Presented Articles of OPSI Conferences}, doi = {}, year = {2015} }
