Título
Electromagnetic field induced resonance tunneling in a quantum point contact
Fecha

Resumen
Recently experimental results described electron transport through a quantum point contact irradiated by an electromagnetic wave in the tunneling regime as a photon-stimulated tunneling. In this work, we study electron tunneling through potential barrier in the presence of an intense electromagnetic field. Using the time-dependent unitary transformation method, the electron scattering by the laser-dressed potential barrier is calculated analytically. It is shown that the potential barrier is modified in the presence of the electromagnetic radiation and electron transmission probability is enhanced with increasing the laser-field strength.
