Quantum geometric scattering of a Dirac particle by a Berry curvature domain wall
Lassaad Mandhour, Frédéric Piéchon
We investigate the scattering of a three-dimensional massless Dirac particle through a domain wall separating two regions with identical energy spectra but distinct Berry curvature…

Theory of local orbital magnetization: local Berry curvature
Sariah Al Saati, Karyn Le Hur, Frédéric Piéchon
We develop a thermodynamic theory of local orbital magnetization based on a perturbative expansion of the magnetic-field-dependent local density of states. Applicable to periodic c…

Scattering of a Dirac particle by a Berry phase domain wall
Lassaad Mandhour, Farah Bouhadida, Frédéric Piéchon
Massless Dirac particles are characterized by an effective pseudospin-momentum locking, which is the origin of the peculiar scattering properties of Dirac particles through potenti…
