  Title

  Non-equilibrium Fermi-edge problem - effect of AC electric field

  Abstract

  In this talk I shall first introduce and review our basic understandings of the equilibrium Fermi-edge problem and the non-equilibrium Fermi-edge problem with an impurity coupled to many reservoirs at different chemical potentials. I shall then consider another non-equilibrium situation where the system under investigation is a single electron reservoir put under an AC electric field. I shall show that the problem can be solved exactly in terms of a well-defined integral. The qualitative behaviors of the solution is discussed.
