Artificial polariton molecules
Alexander Johnston, Kirill P. Kalinin, Natalia G. Berloff
We show that geometrically coupled polariton condensates fabricated in semiconductor devices are versatile systems capable of simulating molecules with given characteristics. In pa…
Polaritonic XY-Ising Machine
Kirill P. Kalinin, Alberto Amo, Jacqueline Bloch +1
Gain-dissipative systems of various physical origin have recently shown the ability to act as analogue minimisers of hard combinatorial optimisation problems. Whether or not these…
Towards Arbitrary Control of Lattice Interactions in Nonequilibrium Condensates
Kirill P. Kalinin, Natalia G. Berloff
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 suc…
Polaritonic network as a paradigm for dynamics of coupled oscillators
Kirill P. Kalinin, Natalia G. Berloff
Photonic and polaritonic lattices have been recently theoretically proposed and experimentally realised as many-body simulators due to the rich behaviors exhibited by such systems…
Matter wave coupling of spatially separated and unequally pumped polariton condensates
Kirill Kalinin, Pavlos G. Lagoudakis, Natalia G. Berloff
Spatial quantum coherence between two separated driven-dissipative polariton condensates created non-resonantly and with a different occupation is studied. We identify the regions…
Exotic states of matter with polariton chains
Kirill Kalinin, Pavlos G. Lagoudakis, Natalia G. Berloff
We consider linear periodic chains of exciton-polariton condensates formed by pumping polaritons non-resonantly into a linear network. To the leading order, such a sequence of cond…
Geometric frustration in polygons of polariton condensates creating vortices of varying topological charge
Tamsin Cookson, Kirill Kalinin, Helgi Sigurdsson +6
Vorticity is a key ingredient to a broad variety of fluid phenomena, and its quantised version is considered to be the hallmark of superfluidity. Circulating flows that correspond…
Optical bistability under non-resonant excitation in spinor polariton condensates
L. Pickup, K. Kalinin, A. Askitopoulos +4
We realise bistability in the spinor of polariton condensates under non-resonant optical excitation and in the absence of biasing external fields. Numerical modelling of the system…
Realizing the Hamiltonian in polariton simulators
Natalia G. Berloff, Kirill Kalinin, Matteo Silva +2
Several platforms are currently being explored for simulating physical systems whose complexity increases faster than polynomially with the number of particles or degrees of freedo…
