    The Role of Symmetry in Quantifying Information

    , M.Sc. Thesis Sharif University of Technology Jabbari, Ghazal (Author) ; Shafie, Afshin (Supervisor)
    Abstract
    In this thesis we want to discuss about a new approach about information. Using this approach, Scott Muller builds his formalism on two basic concepts: distinguishablity and symmetry. His claim is that there is an inverse relation between symmetry and information. It means that if we have a symmetric system we need less information (Than an asymmetric system) to describe it. Here, we are going to explore the role and significance of symmetry in probabilistic distributions of the double-slit experiment, and we want to show if there is a predetermined relation between symmetry and information or not.
     

    Quantum Aspects of The Origin of Life

    , M.Sc. Thesis Sharif University of Technology Khezr Seddigh Mazinani, Shobeir (Author) ; Shafie, Afshin (Supervisor)
    Abstract
    Many have claimed that quantum mechanics is playing a non-trivial, i.e. further from merely governing atomic and molecular realm, in living. If so, clearly quantum mechanics should have played a key role in the origin of life especially in the transition from chemical evolution to biological (Darwinian) evolution. Long before quantum aspects of living systems came to focus, It was known that all the amino acids are right handed and all the sugars are left handed in living systems. Bio-molecules having the same sense of chirality, i.e. optical activity, are called biohomochirality. Detailed studies on the structure and functioning of biomolecules buttressed the idea that the selection of...
