High Energy Particle Theory
We are interested in fundamental aspects of quantum field theory, quantum gravity and string theory. String theory is the only candidate for the unified theory of all known physical phenomena. In addition, it has evolved over the past decade into a remarkably powerful tool to investigate both the strong and weak-coupling regimes of quantum field theory and gravity. This has led to new approaches to understanding strongly coupled field theories such as QCD which are particularly useful when the number of colours is large. Also, the non-zero temperature or baryon charge density properties of QCD can be analyzed using these methods. The group at LUMS SSE is actively working on these aspects of string theory and QCD.
In addition, the group has an interest in more mathematical aspects of string theory, such as topological strings and supersymmetric brane embeddings in various compactifications of string theory.

Spin Physics
The inter-disciplinary, experimental research group focuses on applications of quantum mechanics, especially to nuclear and electronic spin systems. One important test-bed of quantum physics are two-level quantum mechanical systems, called qubits. Electrons and spin-1/2 nuclei are natural candidates to act as qubits. At the Spin Physics Group, we use nuclear magnetic resonance (NMR) and electron spin resonance (ESR) to study fudamental properties of these quantum entities.
We also investigate novel ways of analyzing and improving NMR to enhance our ability to a) study chemical reactions and catalytic processes, espcially in microfludic settings, b) magnetically image structures with higher precision and sensitivity, c) interpret phenomena arising out of the purely geometrical and mathematical structure of quantum state spaces, and e) robust effective control of these processes, borrowing heavily from geometric and group-theoretical control theory.
