"Perfect Pulses"


Israel Klich , Caltech
[Host: Paul Fendley]
ABSTRACT:
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.
