[Host: Paul Fendley]
Generic perturbations of a Fermi liquid create noise in the form of numerous
particle-hole pairs. In the talk I will show that it is possible to excite
particles from a Fermi sea in a noise-free fashion by electromagnetic pulses
of a special form. The resulting many-body states are characterized by a
finite number of particles excited above the Fermi surface accompanied by no
disturbance below it. The excitations can be regarded as realization of
vertex operators. I will also discuss potential applications in creating
entangled electron hole pairs, and effects of interactions.
