A multiphysics data analytic platform is established for imaging poroelastic interfaces of finite permeability (e.g., hydraulic fractures) from elastic waveforms and/or acoustic pore pressure measurements. This accomplished through recent advances in design non-iterative sampling methods to inverse scattering. The direct problem formulated via the Biot equations frequency domain where a network...

We compute the single particle inverse lifetime, evaluated in the superconducting state. Within the BCS framework, the calculation can be done nonperturbatively, i.e. poles can be found well away from the real axis. We find that perturbative calculations are in good agreement with these results, even for non-zero impurity scattering. With electron-phonon scattering added to the problem, we use ...
