Electromagnetically Induced Transparency with Quantized Fields in Optocavity Mechanics [PDF]

open access: yes, 2011
We report electromagnetically induced transparency using quantized fields in optomechanical systems. The weak probe field is a narrow band squeezed field. We present a homodyne detection of EIT in the output quantum field. We find that the EIT dip exists

MHD waves at a spherical interface modelling coronal global EIT waves [PDF]

open access: yes, 2007
Energetically eruptive events such as flares and coronal mass ejections (CMEs) are known to generate global waves, propagating over large distances, sometimes comparable to the solar radius.

The Electromagnetically Induced Transparency in Mechanical Effects of Light [PDF]

open access: yes, 2010
We consider the dynamical behavior of a nanomechanical mirror in a high-quality cavity under the action of a coupling laser and a probe laser. We demonstrate the existence of the analog of electromagnetically induced transparency (EIT) in the output ...

Enhancing sharp features by locally relaxing regularization for reconstructed images in electrical impedance tomography

open access: yesJournal of Electrical Bioimpedance, 2019
Image reconstruction in EIT is an inverse problem, which is ill posed and hence needs regularization. Regularization brings stability to reconstructed EIT image with respect to noise in the measured data.

Crossover from Electromagnetically Induced Transparency to Autler-Townes Splitting in Open V-Type Molecular Systems

open access: yes, 2013
We investigate electromagnetically induced transparency (EIT) and Autler-Townes splitting(ATS) in an open V-type molecular system. Through detailed analytical calculations on the absorption spectrum of probe laser field by using residue theorem and ...
