A sparsity-driven approach for joint SAR imaging and phase error correction [PDF]
IEEE Transactions on Image Processing, 2012 Image formation algorithms in a variety of applications have explicit or implicit dependence on a mathematical model of the observation process. Inaccuracies in the observation model may cause various degradations and artifacts in the reconstructed ...

Correction to the geometric phase by structured environments: the onset of non-Markovian effects [PDF]
, 2015 We study the geometric phase of a two-level system under the presence of a structured environment, particularly analysing its correction with the ohmicity parameter $s$ and the onset of non-Markovianity.

Self-Interaction-Corrected Random Phase Approximation
Journal of Chemical Theory and Computation, 2021 The short-range correlation energy of the random phase approximation (RPA) is too negative and is often corrected by local or nonlocal methods. These beyond-RPA corrections usually lead to a mixed performance for thermodynamics and dissociation properties.
