Steering of topological criticality in the Su-Schrieffer-Heeger chain via non-Hermitian substitutional impurities
Juan A. Cañas, Guo-Qing Zhang, A. Martín-Ruiz
We investigate the topological phase in a one-dimensional Su-Schrieffer-Heeger (SSH) chain in the presence of a finite concentration of non-Hermitian substitutional impurities. Our…
Linear and nonlinear transport responses of topological nodal-line semimetals
L. E. Sosa-Arias, A. Martín-Ruiz
Topological nodal-line semimetals are three-dimensional quantum materials characterized by band crossings that form closed loops in momentum space. In -symmetric real…
Magnetic-field-activated transport from band geometry in gapped nodal-line semimetals
L. Medel Onofre, L. E. Sosa-Arias, A. Martín-Ruiz
We develop a nonperturbative semiclassical theory of magnetotransport in gapped nodal-line semimetals, retaining the full magnetic-field dependence of Berry-curvature and orbital-m…
Non-Hermitian impurity scattering in graphene: Boltzmann transport and thermoelectric response
Juan A. Cañas, Daniel A. Bonilla, A. Martín-Ruiz
We investigate charge and thermoelectric transport in monolayer graphene containing a dilute distribution of finite-range non-Hermitian scattering centers. The impurities are model…
Disorder-induced modulation of the nonlinear Hall effect in Weyl semimetals
Juan A. Cañas, Daniel A. Bonilla, A. Martín-Ruiz
We study the effects of impurity scattering on the nonlinear Hall response of Weyl semimetals within the semiclassical Boltzmann approach. We derive the rectified and second-harmon…
