Charge and spin transport over record distances in GaAs metallic n-type nanowires : II nonlinear charge transport

Hadi Hijazi, Daniel Paget, Guillaume Monier +6

We have investigated the photocarrier charge transport in n-type metallic GaAs nanowires (~ 10^17 cm^-3 doping level), grown by hydride vapor phase epitaxy (HVPE) on Si(111) substr…

Charge and spin transport over record distances in GaAs metallic n-type nanowires : I photocarrier transport in a dense Fermi sea

Hadi Hijazi, Daniel Paget, Guillaume Monier +6

We have investigated charge and spin transport in n-type metallic GaAs nanowires (~ 10^17 cm^-3 doping level), grown by hydride vapor phase epitaxy (HVPE) on Si substrates. This wa…

Parametric amplification of topological interface states in synthetic Andreev bands

Ismael Septembre, Sergei Koniakhin, Julia Meyer +2

A driven-dissipative nonlinear photonic system (e.g. exciton-polaritons) can operate in a gapped superfluid regime. We theoretically demonstrate that the reflection of a linear wav…

Experimental measurement of the divergent quantum metric of an exceptional point

Qing Liao, Charly Leblanc, Jiahuan Ren +6

The geometry of Hamiltonian's eigenstates is encoded in the quantum geometric tensor (QGT). It contains both the Berry curvature, central to the description of topological matter a…

Quantum metric and wavepackets at exceptional points in non-Hermitian systems

D. D. Solnyshkov, C. Leblanc, L. Bessonart +5

The usual concepts of topological physics, such as the Berry curvature, cannot be applied directly to non-Hermitian systems. We show that another object, the quantum metric, which…

Spin-orbit coupling in photonic graphene

Zhaoyang Zhang, Shun Liang, Feng Li +6

We generate experimentally a honeycomb refractive index pattern in an atomic vapor cell using electromagnetically-induced transparency. We study experimentally and theoretically th…
