Composition-tuned smeared phase transitions [PDF]

Physical Review B, 2011
Phase transitions in random systems are smeared if individual spatial regions can order independently of the bulk system. In this paper, we study such smeared phase transitions (both classical and quantum) in substitutional alloys A$_{1-x}$B$_x$ that can

Symmetric phase-alternating composite pulses [PDF]

Journal of Magnetic Resonance (1969), 1987
Abstract We derive sequences of new composite pulses that can provide constant rotations of arbitrary flip angle in the presence of large resonance offset effects. These symmetric sequences use only 180° phase shifts, and have the same symmetry properties as a single radiofrequency pulse.
