Description
We present a scheme for the amplification of electromagnetically induced acoustic transparency
(EIAT) in a superconducting transmon circuit. Recently, EIAT has been demonstrated experimentally
in a three-level ladder-type superconducting artificial atom [G Andersson et al, Phys. Rev. Lett. 124,
240 402 (2020)]. In this experiment, the authors have noticed only 20% transmission of surface
acoustic waves (SAW) due to limited linewidth of the EIT window. Here we utilize an additional
microwave field to enhance the transmission of SAW. This additional field increases the coherence in
the second excited state which causes the amplification in transmission and the reduction in
corresponding group velocity is achieved.
