Nontrivial band geometry in an optically active system
Jiahuan Ren, Qing Liao, Feng Li +6
Optical activity (OA), also called circular birefringence, is known for two hundred years, but its applications for topological photonics remain unexplored. Unlike the Faraday effe…
Direct measurement of the quantum geometric tensor in a two-dimensional continuous medium
A. Gianfrate, O. Bleu, L. Dominici +8
Topological Physics relies on the specific structure of the eigenstates of Hamiltonians. Their geometry is encoded in the quantum geometric tensor containing both the celebrated Be…
Analog Kerr Black hole and Penrose effect in a Bose-Einstein Condensate
D. D. Solnyshkov, C. Leblanc, S. V. Koniakhin +2
Analog physics allows simulating inaccessible objects, such as black holes, in the lab. We propose to implement an acoustic Kerr black hole with quantized angular momentum in a pol…
Optically controlling the emission chirality of microlasers
Nicola Carlon Zambon, Philippe St-Jean, Marijana Milićević +10
Orbital angular momentum (OAM) carried by helical light beams is an unbounded degree of freedom of photons that offers a promising playground in modern photonics. So far, integrate…
Particle-like behavior of topological defects in linear wave packets in photonic graphene
Zhaoyang Zhang, Feng Li, Guillaume Malpuech +7
Topological defects, such as quantum vortices, determine the properties of quantum fluids. The study of their properties has been at the center of activity in solid state and BEC c…
Lasing in optically induced gap states in photonic graphene
M. Milićević, O. Bleu, D. D. Solnyshkov +7
We report polariton lasing in localised gap states in a honeycomb lattice of coupled micropillars. Localisation of the modes is induced by the optical potential created by the exci…
Measuring the Quantum Geometric Tensor in 2D Photonic and Polaritonic Systems
O. Bleu, D. Solnyshkov, G. Malpuech
We first consider a generic two-band model which can be mapped to a pseudospin on a Bloch sphere. We establish the link between the pseudospin orientation and the components of the…
topological insulator analog for vortices in an interacting bosonic quantum fluid
O. Bleu, G. Malpuech, D. D. Solnyshkov
topological insulators for photons and in general bosons cannot be strictly implemented because of the lack of symmetry-protected pseudospins. We show that the requi…
Quantum Valley Hall Effect and Perfect Valley Filter Based on Photonic Analogs of Transitional Metal Dichalcogenides
O. Bleu, D. D. Solnyshkov, G. Malpuech
We consider theoretically staggered honeycomb lattices for photons which can be viewed as photonic analogs of transitional metal dichalcogenides (TMD) monolayers. We propose a simp…
Photonic Versus Electronic Quantum Anomalous Hall Effect
O. Bleu, D. D. Solnyshkov, G. Malpuech
We derive the diagram of the topological phases accessible within a generic Hamiltonian describing quantum anomalous Hall effect for photons and electrons in honeycomb lattices in…
Effective Theory of Non-Adiabatic Quantum Evolution Based on the Quantum Geometric Tensor
O. Bleu, G. Malpuech, D. D. Solnyshkov
We study the role of the quantum geometric tensor (QGT) in the evolution of quantum systems. We show that all its components play an important role on the extra phase acquired by a…
Optical Valley Hall Effect based on Transitional Metal Dichalcogenide cavity polaritons
O. Bleu, D. Solnyshkov, G. Malpuech
We calculate the dispersion of spinor exciton-polaritons in a planar microcavity with its active region containing a single Transitional Metal Dichalcogenide (TMD) monolayer, takin…
Chirality of topological gap solitons in bosonic dimer chains
D. D. Solnyshkov, O. Bleu, B. Teklu +1
We study gap solitons which appear in the topological gap of 1D bosonic dimer chains within the mean-field approximation. We find that such solitons have a non-trivial texture of t…
Interacting quantum fluid in a polariton topological insulator
O. Bleu, D. D. Solnyshkov, G. Malpuech
We study Bogoliubov excitations of a spinor Bose Einstein condensate in a honeycomb periodic potential, in the presence of a Zeeman field and of a spin-orbit coupling specific for…

D. D. Solnyshkov, O. Bleu, G. Malpuech
We propose an implementation of a CNOT quantum gate for quantum computing based on a patterned microcavity polariton system, which can be manufactured using the modern technologica…
