RESEARCH INTERESTS

• I worked on the development of the electronic structure of graphitic nanoparticle where I am in search of the physics of string-like topological defects in condensed matter physics including a theoretical study of fermionic states near string-like defects on the two-dimensional manifolds of different geometry (sphere, cone, hyperboloid, graphitic onions and nanohorns ) within a gauge field-theory model. The local and total densities of states (DOS) near the pentagonal defects (disclinations, dislocations) were calculated for different kind of geometry. I also show how a small elliptic deformation of spherical fullerene, spheroidal fullerenes, evokes a shift of the electronic spectra compared to the spherical ones.
• The aim of my doctoral thesis was to explain the unidirectionality of ET through the RC, where only the one branch L from two possible L, M is active in the electron transfer. The thesis was divided in two major approaches for solving the electron transfer in photosynthetic organisms: the stochastic and nonstochastic models of electron transfer. We have used a model of three sites/molecules (extended to 6 molecules) with electron transfer beginning at site 1 with an option to proceed to site 2 (branch M) or site 3 (branch L). We used a stochastic and nonstochastic sequential (superexchange) model with arbitrary correlation functions. We get the quantum yields of electron escape via the branches L, M in two limiting cases that correspond to a spectral density of underdamped and overdamped Brownian oscillator. In the fast modulation limit of an overdamped regime we get the effect, which was named ``fear of death,'' in which for strong enough sink parameters the electron has a tendency to avoid the place with greater sink. The theoretical models was used to provide a plausible explanation of the temperature dependence of the quantum yields of the Rhodobacter sphaeroides photosynthetic reaction center
