# Toward Arbitrary Control of Lattice Interactions in Nonequilibrium Condensates

@article{Kalinin2019TowardAC, title={Toward Arbitrary Control of Lattice Interactions in Nonequilibrium Condensates}, author={Kirill P. Kalinin and Natalia G. Berloff}, journal={Advanced Quantum Technologies}, year={2019}, volume={3} }

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. Here it is suggested how to overcome this problem and formulate a method for engineering reconfigurable networks of nonequilibrium condensates with control of individual pairwise…
