ABSTRACT
In this talk, we will provide an answer to the question: “What kind of observations (i.e., expectation values) and assumptions are minimally needed to formulate a physical model?” Our answer to this question leads to the new systematic approach of Operational Dynamical Modeling (ODM), which allows deducing equations of motions from time evolution of observables. Using ODM, we are not only able to re-derive well-known physical theories, but also solve open problems in quantum non-equilibrium statistical dynamics. Furthermore, ODM has revealed unexplored flexibilities of nonlinear optics: A shaped laser pulse can drive a quantum system to emit light as if it were a different system (e.g., making lead look like gold). This finding opens new venues in spectroscopy, information processing, and material science.
BIOGRAPHY
Dr. Denys Bondar is an Associate Research Scholar and Lecturer at Princeton University since 2014. He was promoted from a postdoctoral appointment in the group of Prof. Herschel Rabitz at the Department of Chemistry, Princeton University. He received Ph.D. in Physics from the University of Waterloo, Canada in 2011. Dr. Bondar was awarded Humboldt Research Fellowship for Experienced Researchers (2017), U.S. Air Force Young Investigator Research Program (2016), Los Alamos Director’s Fellowship (2013, declined), President’s Graduate Scholarship and Ontario Graduate Scholarship (2010). Driven by the vision of practical realization of quantum technologies, Dr. Bondar conducts a theoretical and computational research at the boundary of quantum thermodynamics and ultrafast nonlinear optics.
