We introduce the theoretical framework we use to study the bewildering variety of phases in condensed--matter physics. We emphasize the importance of the breaking of symmetries, and develop the idea of an order parameter through several examples. We discuss elementary excitations and the topological theory of defects. 
Topological Defects in Physics Essay for the “Differential Geometry in Physics” course
This essay describes the basics of homotopy theory, its relation to group theory and its use in several branches of modern physics for characterising topological defects. The goal of the essay is to

Characterizing the Dynamic Properties of Toron-Umbilic Pairs
Topological defects are studied in many different fields of physics and have recently attracted the attention of researchers due to the interesting applications they provide 15. Liquid crystals,
Computer simulation of the influence of hydrogen on stress–order correlations in amorphous silicon
This paper reports the computational simulation of the correlations between atomic-level stress and local structure fluctuations in a computational model of amorphous silicon. A single parameter has
In this dissertation, we study theoretically ultrafast processes accessible via the interaction of the ultrafast and intense laser pulses with 2D materials. The ultrafast and strong laser pulse has a
Spiral Patterns in Liquid Crystals
The macroscopic configurations of various two-dimensional liquid crystal systems are explored. Aster, vortex and spiral patterns are analyzed for both inactive nematic and polar liquid crystals, as
General description and understanding of the nonlinear dynamics of mode-locked fiber lasers
Research into the attractors’ basins reveals the origin of stochasticity, hysteresis and multistability in these systems and presents a new method for quantitative analysis of these nonlinear phenomena.
Hierarchy, dimension, attractor and self-organization -- dynamics of mode-locked fiber lasers
Mode-locked fiber lasers are one of the most important sources of ultra-short pulses. However, A unified description for the rich variety of states and the driving forces behind the complex and
Local Causal States and Discrete Coherent Structures
A formal theory of coherent structures in fully discrete dynamical field theories is presented, builds on the notion of structure introduced by computational mechanics, generalizing it to a local spatiotemporal setting and offers an unsupervised approach to discover and describe coherent structures.


The topological theory of defects in ordered media
Aspects of the theory of homotopy groups are described in a mathematical style closer to that of condensed matter physics than that of topology. The aim is to make more readily accessible to
