1. On string integrability : A journey through the two-dimensional hidden symmetries in the AdS/CFT dualities
Sammanfattning : One of the main topics in the modern String Theory are the conjectured string/gauge (AdS/CFT) dualities. Proving such conjectures is extremely difficult since the gauge and string theory perturbative regimes do not overlap. In this perspective, the discovery of infinitely many conserved charges, i.e. LÄS MER
2. Development and applications of theoretical algorithms for simulations of materials at extreme conditions
Sammanfattning : Materials at extreme conditions exhibit properties that differ substantially from ambient conditions. High pressure and high temperature expose anharmonic, non-linear behavior, and can provoke phase transitions among other effects. Experimental setups to study that sort of effects are typically costly and experiments themselves are laborious. LÄS MER
3. First Principles Calculations for NOx Reduction over Ag/Al2O3
Sammanfattning : .... LÄS MER
4. Theoretical prediction of properties of atomistic systems : Density functional theory and machine learning
Sammanfattning : The prediction of ground state properties of atomistic systems is of vital importance in technological advances as well as in the physical sciences. Fundamentally, these predictions are based on a quantum-mechanical description of many-electron systems. LÄS MER
5. On transport theory of correlated mesoscopic systems
Sammanfattning : This thesis is about the theory of quantum transport through low dimensional correlated systems. Correlated systems are interacting many-particle systems where collective effects predominate over the individual properties of particles whereof they consist. Single particle approach to correlated systems would be essentially wrong. LÄS MER
