Topological moiré polaritons
I. Septembre, C. Leblanc, D. D. Solnyshkov +1
The combination of an in-plane honeycomb potential and of a photonic spin-orbit coupling (SOC) emulates a photonic/polaritonic analog of bilayer graphene. We show that modulating t…
Design of a room-temperature topological exciton-polariton laser in a ZnO/TiO-photonic crystal slab
I. Septembre, C. Leblanc, L. Hermet +4
We propose theoretically a scheme to get a room-temperature 2D topological exciton-polariton laser with propagating topological lasing modes. The structure uses guided modes in a p…
Domain-wall topology induced by spontaneous symmetry breaking in polariton graphene
D. D. Solnyshkov, C. Leblanc, I. Septembre +1
We present a numerical study of exciton-polariton (polariton) condensation in a staggered polariton graphene showing a gapped s-band at the and valleys. The condensation o…
Giant effective Zeeman splitting in a monolayer semiconductor realized by spin-selective strong light-matter coupling
T. P. Lyons, D. J. Gillard, C. Leblanc +11
Strong coupling between light and the fundamental excitations of a two-dimensional electron gas (2DEG) are of foundational importance both to pure physics and to the understanding…
Universal semiclassical equations based on the quantum metric
C. Leblanc, G. Malpuech, D. D. Solnyshkov
We derive semiclassical equations of motion for an accelerated wavepacket in a two-band system. We show that these equations can be formulated in terms of the static band geometry…
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…
High-Frequency Exciton-Polariton Clock Generator
C. Leblanc, G. Malpuech, D. D. Solnyshkov
Integrated circuits of photonic components are the goal of applied polaritonics. Here, we propose a compact clock generator based on an exciton-polariton micropillar, providing opt…
Chromodynamics of photons in an artificial non-Abelian magnetic Yang-Mills field
A. Fieramosca, L. Polimeno, G. Lerario +12
Artificial gauge fields, simulating real phenomenologies that unfold in a vast variety of systems, offer extraordinary possibilities to study extreme physical effects in many diffe…
