J. Chem. Phys – Multidimensional Pseudospectral Method

Justin Ruths lead authors a paper describing the technical details and practical implementation of the multidimensional pseudospectral method for optimal ensemble control problems.  We specifically look at several important problems in quantum control and show the robustness and effectiveness of the method.

PNAS – A Unified Method for Quantum Pulse Design

In collaboration with Gerhard Wagner group at the Harvard Medical School, Dr. Li and Justin Ruths present their new computational method for solving challenging pulse design problems in nuclear magnetic resonance (NMR) and imaging (MRI).  The paper describes a systematic way to mathematically characterize and then numerically solve these problems. The experiments provided by Wagner’s [...]

Phys. Rev. A – Frictionless Atom Cooling

Dionisis Stefanatos lead authors the accepted paper in Physical Review A regarding a time optimal approach to solving the problem of frictionless atom cooling in harmonic traps.  In this work we permit the trap frequency to take on imaginary values for transient time intervals, which leads to a modified formulation and solution of this problem.  [...]
