#### Vortices Interaction

#### in 2D XY model

Review of 2D XY model and a brief summary of the calculation for the topological defects in the system (vortices) interact.

#### Collective Behaviors

#### of Vortices in 2D XY model

Examine the Renormalization Group flow and interpreted the collective behaviors of vortices in term of phase transitions.

#### Collective Behaviors

#### of Vortices in thin slab

#### Superconductor of Type I & II

Show interesting collective behaviors of the topological defects.
