Quantum Energy Transfer in the Selectivity Filter 26 Backbone of the Ion Channels in Neurons Hassan Bassereh h bassereh@ph iut ac ir 1 17 2015 Department of Physics Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Dr Vahid Salari vahidsalari@cc iut ac ir Dr Farhad Shahbazi shahbazi@cc iut ac ir Abstract Energy and charge transfer are the most important phenomena in physics and biology For example charge transfer in DNA and charge or energy transfer in photosynthesis are the best examples Recently it has been shown that quantum mechanical e ects play important role in excitation energy transfer through photosynthetic structures In this thesis we brie y review open quantum systems in general and then focus on energy transfer in a linear chain with dipole dipole interaction Then we simulate a toy model for a linear protein structure in di erent states ordered disordered static and dynamical states and investigate energy transfer inside the above structure The simulated protein is a p loop strand in the selectitivity lter of an ion channel in an excitable cell In our study we have investigated the role of noise and dissipation in all states Our results indicate that system e ciency exponentially decays in terms of dissipation for disordered chain but decays as a power law for ordered chains On the other side the e ect of noise is constructive for the disordered chain but it is destructive for the ordered chain As a result since the linear protein is intrinsically disordered thus the role of noise can be constructive for living systems Moreover we have studied the collaborative role of classical and quantum mechanical e ect together to see whether the classical e ects are stronger than the quantum mechanical e ects or not Our results show that the best e ciency is obtained in equal contributions for both quantum mechanical and classical e ects This type of collaboration can make the functioning of the ion channel more e cient and quicker Keywords Open Quantum Systems Energy Transfer Ion Channels
