en عمومى General پژوهشي Research <p>Considering a temperature dependent two-level quantum system, we have numerically solved the Landau-Zener transition problem. The method includes the incorporation of temperature effect as a thermal noise added Schr&ouml;dinger equation for the construction of the Hamiltonian. Here, the obtained results which describe the changes in the system including the quantum states and the transition probabilities are investigated and discussed. The results successfully describe the behavior of the transition probabilities by sweeping the temperature.</p> Two level system, Landau-Zener, avoided crossing, Temperature effects, 57 62 http://ijop.ir/browse.php?a_code=A-10-527-1&slc_lang=en&sid=1 Mehdi Hosseini mehdihosseini@sutech.ac.ir 10031947532846001818 10031947532846001818 Yes Shiraz University of Technology Farrokh Sarreshtedari f.sarreshtedari@ut.ac.ir 10031947532846001819 10031947532846001819 No University of Tehran
