Rectified Quantum Orders and Quantum Printing

Quantum matter out of equilibrium emerges as an important platform to induce transient quantum orders. Modern techniques of coherent and fast light sources enable this evolution. Nonequilibrium orders have been seen in driven cold atoms, spins, magnetism and superconductivity. To place these ideas in a broader context I will introduce the concepts of rectified quantum orders and quantum printing as our approach to induce controlled quantum states. I will present recent theory predictions and experimental observations of induced orders: magnetization induced in paraelectric [1] and light-induced vortex excitations in superconductors [2].
