APPLIED PHYSICS GRADUATE PROGRAMJoint PhD Program Between Weinberg College and Mccormick School of Engineering

Research Interests

The Seideman group is engaged in theoretical research at the broad interface between chemistry, physics and material sciences. Specific topics of interest include:

• coherent control and coherence spectroscopies in isolated molecules and in dissipative media;
• quantum transport, molecular electronics, current-driven nanochemistry and molecular machines;
• ultrafast nanoplasmonics and light manipulation in the nanoscale;
• the interaction of matter with intense laser fields;
• photomanipulation of external molecular modes;
• mathematical method development.

Of particular relevance to the Applied Physics Program is the group’s research on molecular nonadiabatic alignment by moderately intense laser pulses, an approach that evolved, during the past decade, from a theoretical dream¹ into a rich field of experimental and numerical research and the topic of hundreds of publications.² Currently we are particularly excited about the application of laser alignment to coherently control electric transport in the nanoscale,³  and about opportunities in solution chemistry⁴ and in attosecond physics.⁵
