Exceptional points and phase transitions in non-Hermitian binary systems
Amir Rahmani, Andrzej Opala, Michał Matuszewski
Recent study demonstrated that steady states of a polariton system may show a first-order dissipative phase transition with an exceptional point that appears as an endpoint of the…
The role of all-optical neural networks
Michał Matuszewski, Adam Prystupiuk, Andrzej Opala
In light of recent achievements in optical computing and machine learning, we consider the conditions under which all-optical computing may surpass electronic and optoelectronic co…
Natural exceptional points in the excitation spectrum of a light-matter system
Andrzej Opala, Magdalena Furman, Mateusz Król +7
We observe natural exceptional points in the excitation spectrum of an exciton-polariton system by optically tuning the light-matter interactions. The observed exceptional points d…
Harnessing exciton-polaritons for digital computing, neuromorphic computing, and optimization
Andrzej Opala, Michał Matuszewski
Polaritons are quasiparticles resulting from strong quantum coupling of light and matter. Peculiar properties of polaritons are a mixture of physics usually restricted to one of th…
Analogue Spin Simulators: How to keep the Amplitude Homogeneous
Wouter Verstraelen, Piotr Deuar, Michał Matuszewski +1
A setup that simulates ground states of spin graphs would allow one to solve computationally hard optimisation problems efficiently. Current optical setups to this goal have diffic…
Non-Hermitian synthetic lattices with light-matter coupling
Amir Rahmani, Mateusz Kędziora, Andrzej Opala +1
We propose that light-matter coupling can be used to realize synthetic lattices. In particular, we consider a one-dimensional chain of exciton-photon sites to create a comb lattice…
