In a paper by M. Misko, A.Putintsev et al., the Skoltech team with colleagues from Universität Wuppertal develop a microscopic theory accounting for thermalization, vibron relaxation, and kinetic bimolecular quenching of polaritons and excitons to investigate the intrinsic limitations of the temporal separation of consecutive polariton condensates. We test and verify our theoretical predictions using an optical pump-pump configuration with different pulse widths and unravel the importance of kinetic losses in defining the upper limit of the temporal bandwidth, reaching ∼240GHz.

In a paper by M. Kolker et al., the Skoltech team with colleagues from ITMO University reports achievement of tunable polariton emission on CsPbBr3 perovskite crystals at room temperature. By using a point squeezing device to change the effective length of a multi-𝝀 planar microcavity, a tunable polariton emission >23 nm in the green region of the spectrum was obtained. The result demonstrates the versatility of perovskites as a platform for further applications.

In a publication in Science Advances, researchers from Skoltech, Universitat Politècnica de València, Institute of Spectroscopy of RAS, University of Warsaw and University of Iceland, have reported on the correlation between the emergent vortex patterns in triangular lattice of coupled quantum vortices and the low-energy solutions of the corresponding antiferromagnetic Ising system. Our team investigated formation and synchronization of quantum vortices in optically trapped microcavity polaritons. Due to coupling, the pairs of neighbouring condensates in the lattice self-arrange their orbital angular momentum antiparallel, implying a form of artificial orbital “antiferromagnetism” in triangular geometry. This study offers a path toward spontaneously ordered vortex arrays with nearly arbitrary configurations and controlled couplings.

In a paper published in Optica, Sk team, together with Dr. H. Sigurdsson from the University of Iceland and University of Warsaw, reveals the effect of an all-optically driven spin precession in microcavity polariton condensates. This work continues our previous research on the topic, where we demonstrated the possibility to induce vortices in rotating polariton condensates (Sci. Adv. 9, eadd1299 (2023); Phys. Rev. B 109, 104503 (2024).).

In a paper by A. Putintsev et al., our team with colleagues reports on the quantum statistical properties of organic polariton condensates. It is shown that unlike a conventional laser, the organic polariton condensate tends to increase its noise level above shot-noise fluctuations due to a complex interplay between polariton thermalization, cavity lifetime, and kinetic losses originating from the quantum fluid properties of polariton condensates. The work comes from collaborative efforts from the Skoltech team and colleagues from Dukhov Research Institute of Automatics (VNIIA), Moscow Institute of Physics and Technology, Institute for Spectroscopy RAS, Moscow Institute of Electronics and Mathematics, and Bergische Universität Wuppertal.

The work of Prof. Natalia Berloff (Skoltech & University of Cambridge) is featured in the inside back cover of Advanced Quantum Technologies. There is a growing interest in investigating new states of matter using out‐of‐equilibrium lattice spin models in two dimensions. However, a control of pairwise interactions in such systems has been elusive as due to their nonequilibrium nature they maintain nontrivial particle fluxes even at the steady state. In this work, we suggest how to overcome this problem and formulate a method for engineering reconfigurable networks of nonequilibrium condensates with control of individual pairwise interactions.

Lectures by leading academics were attended throughout the day by representatives of the academic community and relevant industrial partners. The topics covered the full scope of modern polaritonics, from the more traditional foundations of the field to new exotic physics. Attendees were afterwards given the opportunity to visit the Skoltech Hybrid Photonics Labs where the lab technologies were demonstrated. An event dinner was organized in the evening, during which attendees could discuss the state of the field and plan future endeavours.

Prof. Berloff (Skoltech & University of Cambridge) presented today the results of her research using polariton platforms for solving hard optimization problems "mappable" into the XY model, at an Open Colloquium organized by the Russian Quantum Center at the National University of Science and Technology MISIS. In her talk, she discussed the range of optimization problems that can be efficiently solved by polariton graphs and focused on elucidating the relationship between the energy spectrum of the XY Hamiltonian and the total number of condensed polariton particles. This theory underpinned the recent Nature Materials publication "Realizing the classical XY Hamiltonian in polariton simulators", a fruit of the Quantum Polaritonics Partnership.

The work of Prof. Lagoudakis (Skoltech & University of Southampton) is highlighted on the cover of Light Science & Application. The result of fruitful collaboration with Polish colleagues at the University of Warsaw and at the Institute of Applied Physics of the Military University of Technology, the article, "Tunable optical spin Hall effect in a liquid crystal microcavity", demonstrates for the first time external control of spin currents by modulating the splitting between transverse electric and magnetic fields in liquid crystals integrated in microcavities.

We are glad to see our work highlighted on the back cover of Advanced Optical Materials. A collaboration of researchers of the Quantum Polaritonics Partnership with colleagues at the University of Sheffield, the article "A Yellow Polariton Condensate in a Dye Filled Microcavity" demonstrates polariton condensation in the yellow part of the visible spectrum from a planar organic semiconductor microcavity containing the molecular dye bromine‐substituted boron‐dipyrromethene. Such structures maybe be of interest in the development of new devices, including high-efficiency lasers and light-sources.

The researchers of the Partnership are proud to see their work published today in the prestigious journal Nature Materials. The article, Realizing the classical XY Hamiltonian in polariton simulators, is the culmination of several years of intense collaboration between Skoltech, the University of Southampton and the University of Cambridge. By showing how polaritonics platforms can be used to map computationally complex problems into a classical spin system, such as the XY model, this is a very exciting development for the whole field of polaritonics. Big congratulations to all researchers involved!
