Log-Periodic Oscillations in the Photo Response of Efimov Trimers

arXiv:1310.8582 · doi:10.1007/s00601-014-0879-2

Abstract

The photoassociation of Efimov trimer, composed of three identical bosons, is studied utilizing the multipole expansion. For identical particles the leading contribution comes from the r^2 s-mode operator and from the quadrupole d-mode operator. Log-periodic oscillations are found in the photoassociation response function, both near the energy threshold for the leading s-wave reaction, and in the high frequency tail for all partial waves.
