    "abstract": "Laser-atom interaction can be an efficient mechanism for the production of\ncoherent electrons. We analyze the dynamics of monoenergetic electrons in the\npresence of uniform, perpendicular magnetic and electric fields. The Green\nfunction technique is used to derive analytic results for the field--induced\nquantum mechanical drift motion of i) single electrons and ii) a dilute Fermi\ngas of electrons. The method yields the drift current and, at the same time it\nallows us to quantitatively establish the broadening of the (magnetic) Landau\nlevels due to the electric field: Level number k is split into k+1 sublevels\nthat render the $k$th oscillator eigenstate in energy space. Adjacent Landau\nlevels will overlap if the electric field exceeds a critical strength. Our\nobservations are relevant for quantum Hall configurations whenever electric\nfield effects should be taken into account.",
