Symmetry has played a crucial role in our understanding of physical systems. In this thesis, we review several works based on investigating the symmetry properties of theories. We examine and improve the Noether's theorem and the coset construction,
The Equivalence Between the Kitaev, the Transverse Quantum Ising Model and the Classical Ising Model

Classical thermodynamic phase transitions have been studied since the 19th centuryand are driven by thermal fluctuations. By contrast, the more recently discoveredquantum phase transitions are driven by quantum fluctuations and may occur evenat zero

Strain control of correlated electron phenomena has been a theme of condensed matter research in recent years. Two primary areas of investigation have been controllable symmetry breaking and measurements of susceptibility with respect to elastic defo

We probe the effects of applying an external magnetic field to Kitaev's spin S=1/2 model on a honeycomb lattice [1] and study this model's low-lying energy excitations across varying field strengths (and field orientations) using exact diagonalizatio
