Phase Retrieval with Sparse Phase Constraint [PDF]
SIAM Journal on Mathematics of Data Science, 2020 For the first time, this paper investigates the phase retrieval problem with the assumption that the phase (of the complex signal) is sparse in contrast to the sparsity assumption on the signal itself as considered in the literature of sparse signal processing.

Phase retrieval with random phase illumination [PDF]
Journal of the Optical Society of America A, 2012 This paper presents a detailed, numerical study on the performance of the standard phasing algorithms with random phase illumination (RPI). Phasing with high resolution RPI and the oversampling ratio $σ=4$ determines a unique phasing solution up to a global phase factor. Under this condition, the standard phasing algorithms converge rapidly to the true

Phases, phase equilibria, and phase rules in low-dimensional systems [PDF]
The Journal of Chemical Physics, 2015 We present a unified approach to thermodynamic description of one, two, and three dimensional phases and phase transformations among them. The approach is based on a rigorous definition of a phase applicable to thermodynamic systems of any dimensionality. Within this approach, the same thermodynamic formalism can be applied for the description of phase

Phase Transitions in Phase Retrieval [PDF]
, 2015 Consider a scenario in which an unknown signal is transformed by a known linear operator, and then the pointwise absolute value of the unknown output function is reported. This scenario appears in several applications, and the goal is to recover the unknown signal -- this is called phase retrieval. Phase retrieval has been a popular subject of research
