1. Computer Simulations of Simple Liquids with Tetrahedral Local Order : the Supercooled Liquid, Solids and Phase Transitions
Abstract : The understanding of complex condensed matter systems is an area of intense study. In this thesis, some properties of simple liquids with strong preference for tetrahedral local ordering are explored. These liquids are amenable to supercooling, and give complex crystalline structures on eventual crystallisation. READ MORE

2. Relaxation dynamics of perturbed water and other H-bonded liquids
Abstract : Most liquids can be supercooled below its melting point where the dynamics dramatically slows down with decreasing temperature until the material appears solid on the experimental time scale and becomes stuck in an out-of-equilibrium configuration, a glass. Water, one of the most abundant substances on earth, is no exception. READ MORE

3. X-Ray Investigations of the Liquid-Liquid Critical Point Hypothesis in Supercooled Water
Abstract : This thesis presents experimental x-ray scattering studies on supercooled liquid water. A liquid-liquid transition between two structurally distinct configurations has been found in deeply supercooled water, indicating the existence of a liquid- liquid critical point. READ MORE

4. Computer simulations of condensed phases with icosahedral local order
Abstract : Understanding the fundamental aspects, and the formation mechanisms of glasses remains an outstanding unsolved problem of condensed-matter physics.Glass-formation in simple atomic systems is generally associated with the icosahedral local order. READ MORE

5. Simulation of relaxation processes in complex condensed matter systems : Algorithmic and physical aspets
Abstract : This thesis summarizes interrelated simulation studies of three different physical phenomena. The three topics are: simulation of work hardening of materials using dislocation dynamics, investigation of anomalous diffusion in supercooled liquids using molecular dynamics,and kinetic Monte-Carlo simulation of annealing of radiation damaged materials.
