CAREER: Exploring the Structure of M Theory

点击翻译按钮获取中文摘要

Research in theoretical particle physics will include work on superstringtheory, and quantum field theory. Techniques which do not requireapproximations will primarily be used to explore the structure of bothsuperstring theory and quantum field theory: particularly through the useof symmetry, and via the interplay between superstring theory and quantumfield theory. Quantum field theory is the conventional framework fordescribing elementary particles and their interactions. On the other hand,superstring theory is the exciting candidate for a quantum theory ofgravity, which also provides a unified framework for all the fundamentalforces. Understanding the complete structure of superstring theory is ofcentral importance in our attempt to answer basic questions about the natureof space-time and gravity.
