Pencil-beam approximation of stationary Fokker-Planck
Guillaume Bal, Benjamin Palacios
Solutions of stationary Fokker-Planck equations in the narrow beam regime are commonly approximated by either ballistic linear transport or by a Fermi pencil-beam equation. We pres…
Inverse source problems in transport via attenuated tensor tomography
Guillaume Bal, François Monard
We establish results for the injectivity and injectivity modulo gauge of certain inverse source problems in transport on a simply connected domain with variable index of refraction…
Topological invariants for interface modes
Guillaume Bal
We consider topologically non-trivial interface Hamiltonians, which find several applications in materials science and geophysical fluid flows. The non-trivial topology manifests i…
Photo-acoustic tomography in a rotating setting
Guillaume Bal, Adrian Kirkeby
Photo-acoustic tomography is a coupled-physics (hybrid) medical imaging modality that aims to reconstruct optical parameters in biological tissues from ultrasound measurements. As…
