Research Project

My PhD project is to use DMRG, which is an accurate and versatile numerical method in computational condensed matter physics, to study the dynamics of dissipative quantum systems. A Dissipative system is a system coupled to an environment which exchanges energy and matter with it. Classical examples are cyclones and life. Quantum effects become important at the nanoscale and sometimes play the key role. Those dissipative system governed by quantum mechanics are called dissipative quantum systems. A very good theoretical understanding of them is not only very important in quantum theory but also will help experimentalists and engineers to devise future nanoscale and quantum based applications.
