Time crystallinity in open quantum systems
Andreu Riera-Campeny, Maria Moreno-Cardoner, Anna Sanpera
Time crystals are genuinely non-equilibrium quantum phases of matter that break time-translational symmetry. While in non-equilibrium closed systems time crystals have been experim…

Extraordinary subradiance with lossless excitation transfer in dipole-coupled nano-rings of quantum emitters
Maria Moreno-Cardoner, David Plankensteiner, Laurin Ostermann +2
A ring of sub-wavelength spaced dipole-coupled quantum emitters possesses only few radiant but many extraordinarily subradiant collective modes. These exhibit a 3D-confined spatial…
