Selective excitation of a vibrational level within the electronic ground state of a polyatomic molecule with ultra short pulses

Author: De Clercq, L ; Botha, L ; Uys, H ; Du Plessis, A ; Rohwer, E Date: Sep 2010 Coherent control of the upper vibrational level populations in the electronic ground state of a polyatomic molecule was simulated. Results indicate that selective excitation of a specific upper state level is possible. Read more
Spectroscopy and thermometry of drumhead modes in a mesoscopic trapped-ion crystal using entanglement

Author: Sawyer, BC ; Britton, JW ; Keith, AC ; Joseph Wang, CCJ ; Freericks, JK ; Uys, H ; Biercuk, MJ ; Bollinger, JJ Date: May 2012 We demonstrate spectroscopy and thermometry of individual motional modes in a mesoscopic 2D ion array using entanglement-induced decoherence as a method of transduction. Our system is a 400 µm-diameter planar crystal of several hundred 9Be+ ... Read more
Topology of the landscape of optimally controlled transitions in a multilevel system

Author: Madigoe, RJ ; Botha, LR ; Uys, H ; Rohwer, EG ; Smit, A Date: Oct 2012 According to a theoretical analysis, the control landscape of many quantum control problems has a very favourable topology regardless of the detailed nature of the Hamiltonian, provided that one has full control of the system. It is obvious ... Read more
