Topological turbulence in spin-orbit-coupled driven-dissipative quantum fluids of light generates high angular momentum states

S. V. Koniakhin, G. Malpuech, D. D. Solnyshkov +1

We demonstrate the formation of a high angular momentum turbulent state in an exciton-polariton quantum fluid with TE-TM Spin-Orbit Coupling (SOC). The transfer of particles from q…

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…

Analogue time machine in a photonic system

D. D. Solnyshkov, G. Malpuech

Analogue physics has successfully tackled the problems of chromodynamics, event horizons, Big Bang and Universe expansion, and many others. Here, we suggest a photonic model system…

Dynamics of spin polarization in tilted polariton rings

S. Mukherjee, V. K. Kozin, A. V. Nalitov +9

We have observed the effect of pseudo magnetic field originating from the polaritonic analog of spin-orbit coupling (TETM splitting) on a polariton condensate in a ring-shaped m…

Analysis and fabrication of a photonic crystal based anti-reflective coating for photovoltaics generated by evolutionary optimization

Pauline Bennet, Perrine Juillet, Sara Ibrahim +7

We optimize multilayered anti-reflective coatings for photovoltaic devices, using modern evolutionary algorithms. We apply a rigorous methodology to show that a given structure, wh…

A Novel Occupancy Mapping Framework for Risk-Aware Path Planning in Unstructured Environments

Johann Laconte, Abderrahim Kasmi, François Pomerleau +4

In the context of autonomous robots, one of the most important tasks is to prevent potential damage to the robot during navigation. For this purpose, it is often assumed that one m…

Monitoring the edges of a graph using distances

Florent Foucaud, Shih-Shun Kao, Ralf Klasing +2

We introduce a new graph-theoretic concept in the area of network monitoring. A set of vertices of a graph is a \emph{distance-edge-monitoring set} if for every edge of…

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…

Complexity and Approximation for Discriminating and Identifying Code Problems in Geometric Setups

Sanjana Dey, Florent Foucaud, Subhas C Nandy +1

We study geometric variations of the discriminating code problem. In the \emph{discrete version} of the problem, a finite set of points and a finite set of objects are give…

Tree pivot-minors and linear rank-width

Konrad K. Dabrowski, François Dross, Jisu Jeong +4

Tree-width and its linear variant path-width play a central role for the graph minor relation. In particular, Robertson and Seymour (1983) proved that for every tree~, the class…
