Statistical Physics:

Simulation study of spin models in two-dimensions (6 unit)

In this project the student will perform Monte Carlo simulation of two-dimensional lattice spin models with advanced techniques such as entropic sampling. There is also opportunity to do analytical work to understand the origin of weak first order transitions and the effect of vacancies on the nature of the phase transition.


Interdisciplinary topics:

Bacterial chemotaxis (3/6 unit) - Student ID: 16206231

Bacteria perform swim-and-tumble motion to sense their chemical environment and drift towards region of higher nutrient concentration and away from harmful chemicals. This phenomenon can be studied at various levels, from the sensing of individual molecules to the processing of the information inside the cell and onto the control of the cell motility machinery. In addition, communication channels between bacteria can be established and it is possible to modify the chemotaxis circuit to generate other types of group bahavior. In this project the student will learn about the chemotaxis system at various levels of detail and perform simulations of the system using appropriate models.


Scale-free and social networks (3 unit)

(http://en.wikipedia.org/wiki/Scale_free_network)

Learn some basic properties of networks, the origin of such networks in physical science and social contexts, and various dynamic processes that can be defined on networks. Collect your own data and perform the analysis to extract hidden information about the system.
