Quantum Phases and Entanglement in an Optically Active Solution of Amino Acids

In optical active medium (OPM) the physics behind the rotation of plane of polarization of incident plane polarized light has been studied from the view point of transfer of energy and angular momentum and quantum entanglement. The absorbed energy of the polarized light in the optical active medium induces the mechanical rotation of the chiral molecule. Quantum mechanically the molecule acquires the quantum phase due to passage of the polarized light. As the chiral molecule has fixed helicity, the phase is helicity dependent or spin angular momentum (SAM) phase. The rotation of plane of polarization is due to equivalence between Optical and mechanical torque in the optically active medium. Polarized light has its OAM dependence on intensity of light. The loss of intensity or reduction of OAM is proportional to the concentration of the optical active medium. This indicates a transfer of angular momentum occur between light and chiral molecule. Moreover, in this work we first focused on the quantum correlation of polarized photon and chiral molecules which is realized by the form of a singlet state through quantum entanglement. This theoretical knowledge has been reflected experimentally to find the comparative study of absorbed intensity and geometric phase of six essential and five non-essential amino acids.
