All-optical switching at the two-photon limit with interference-localized states
Ville A. J. Pyykkönen, Grazia Salerno, Jaakko Kähärä +1
We propose a single-photon-by-single-photon all-optical switch concept based on interference-localized states on lattices and their delocalization by interaction. In its 'open' ope…

Suppression of non-equilibrium quasiparticle transport in flat band superconductors
Ville A. J. Pyykkönen, Sebastiano Peotta, Päivi Törmä
We study non-equilibrium transport through a superconducting flat-band lattice in a two-terminal setup with the Schwinger-Keldysh method. We find that quasiparticle transport is su…
