Far-field interference of a neutron white beam and the applications to noninvasive phase-contrast imaging
(American Physical Society, 2017-04-26)The phenomenon of interference plays a crucial role in the field of precision measurement science. Waveparticle duality has expanded the well-known interference effects of electromagnetic waves to massive particles. The ... -
Fast control and decoherence in superconducting quantum circuits
(University of Waterloo, 2015-08-24)This thesis discusses a series of experimental and theoretical studies on fast control and decoherence in superconducting quantum circuits. These two subjects are complementary aspects of the problem of improving the gate ... -
Fast Stochastic Global Optimization Methods and Their Applications to Cluster Crystallization and Protein Folding
(University of Waterloo, 2005)Two global optimization methods are proposed in this thesis. They are the multicanonical basin hopping (MUBH) method and the basin paving (BP) method. <br /><br /> The MUBH method combines the basin hopping (BH) ... -
Fast Switchable Ultrastrong Coupling Between Superconducting Artificial Atoms and Electromagnetic Fields
(University of Waterloo, 2019-08-23)This thesis consists of two parts: the main part is a theoretical investigation of the ultrastrong coupling regime for atom-light coupling in superconducting circuits, and the second part is concerned with the development ... -
Feasibility of Injecting Large Volumes of CO2 into Aquifers
(Elsevier, 2009-02)Although it is recognized that deep aquifers offer a very large potential storage capacity for CO2 sequestration it is not clear how to fill the storage with a large volume of CO2 in a relatively short period of time. The ... -
Feasibility of Testing the Event Formalism with Refractive Materials
