Abstract/Description: We study the unusual transport behavior driven mostly by the correlations between the charge carriers in lattice and continuum systems. The strongly correlated systems are studied in the classical limit where the Coulomb interaction dominates the systems and brings the systems into the nearly frozen state that we call Coulomb Liquids. Theoretical description of the materials with the strongly interacting electron systems in the lattice or solid state physics and ions in biological systems or solutions are constantly challenging problems in condensed matter physics and biophysics. First we investigate the non-activated behavior of transport that observed near Wigner crystallization in two dimensions electron gas (2DEG) that is observed experimentally. The effect of Coulomb interaction in the system is studied with Monte Carlo (MC) simulation and extended dynamical mean field theory (EDMFT) in hypercubic lattice and pseudogap phase is found as a robust feature driven by long-range interaction. In the second part of the thesis we study the effect of geometrical frustration in pyrochlore lattice which competes with the interaction-driven frustration. The MC and EDMFT methods give pseudo-gap phase as found in cubic lattice that has no geometrical frustration and agree with the unusual transport property of ancient magnet/magnetite above the Verwey transition. The third part discusses the effect of strongly-correlated liquid (SCL) model by Shklovskii and the mean-field approach of Poisson-Boltzmann equation (PBE) describing the screening of macro-ions in solution or biological system. We compare those approximations with MC simulation and explain which approximation is good at different limit of temperature or ion density. And the last part describes the visualization for different type of interactions and the effect of filling, disordered, etc. from the study of Coulomb liquids.
