Coherent control of quantum states by quadratically chirped short laser pulses
G. P. Djotyan, A. A. Avetisyan, A. P. Djotyan
We present a novel scheme for coherent manipulation of populations and robust creation of arbitrary coherent superposition of metastable states of a quantum system with lambda conf…
Nonlinear Properties of Gated Graphene in a Strong Electromagnetic Field
A. A. Avetisyan, A. P. Djotyan, K. Moulopoulos
We develop a microscopic theory of a strong electromagnetic field interaction with gated bilayer graphene. Quantum kinetic equations for density matrix are obtained using a tight b…
D- shallow donor near a semiconductor-metal and a semiconductor-dielectric interface
Y. L. Hao, A. P. Djotyan, A. A. Avetisyan +1
The ground state energy and the extend of the wavefunction of a negatively charged donor (D-) located near a semiconductor-metal or a semiconductor-dielectric interface is obtained…
Stacking Order dependent Electric Field tuning of the Band Gap in Graphene Multilayers
A. A. Avetisyan, B. Partoens, F. M. Peeters
The effect of different stacking order of graphene multilayers on the electric field induced band gap is investigated. We considered a positively charged top and a negatively charg…
