Adiabatic and quasi-adiabatic evolutions are crucial in the development of protocols for quantum control and, in general, manipulation of quantum states, which in turn are very important in such fields as nanotechnologies and quantum computation. In this wide class of quantum evolutions characterized by slowly varying Hamiltonians, Landau-Zener and STIRAP processes are among the most popular. Their real exploitability requires anyway an accurate analysis of possible detrimental effects of the environment-induced quantum noise, which can dramatically affect the final result of an experiment. In this seminar I will discuss the role of the environment on adiabatic and quasi-adiabatic processes, especially in the Markovian limit, also bringing to light some unusual behaviors traceable back to the occurrence of quantum Zeno phenomena.
