Annihilation of exceptional points from different Dirac valleys in a 2D photonic system

M. Król, I. Septembre, P. Oliwa +13

Topological physics relies on the existence of Hamiltonian's eigenstate singularities carrying a topological charge, such as quantum vortices, Dirac points, Weyl points and -- in n…

Lasing in the Rashba-Dresselhaus spin-orbit coupling regime in a dye-filled liquid crystal optical microcavity

Marcin Muszyński, Mateusz Król, Katarzyna Rechcińska +9

In the presence of Rashba-Dresselhaus coupling, strong spin-orbit interactions in liquid crystal optical cavities result in a distinctive spin-split entangled dispersion. Spin cohe…

Energy-efficient neural network inference with microcavity exciton-polaritons

M. Matuszewski, A. Opala, R. Mirek +8

We propose all-optical neural networks characterized by very high energy efficiency and performance density of inference. We argue that the use of microcavity exciton-polaritons al…

Giant spin Meissner effect in a non-equilibrium exciton-polariton gas

M. Król, R. Mirek, D. Stephan +7

The suppression of Zeeman energy splitting due to spin-dependent interactions within a Bose-Einstein condensate (the spin Meissner effect) was predicted to occur up to a certain va…

Effect of magnetic field on the lasing threshold of a semimagnetic polariton condensate

J. -G. Rousset, B. Piętka, M. Król +5

We evidence magnetic field triggered polariton lasing in a microcavity containing semimagnetic quantum wells. This effect is associated with a decrease of the polariton lasing thre…

Angular dependence of giant Zeeman effect for semi-magnetic cavity polaritons

R. Mirek, M. Król, K. Lekenta +7

The observation of spin-related phenomena of microcavity polaritons has been limited due to weak Zeeman effect of non-magnetic semiconductors. We demonstrate that the incorporation…
