A universal Doppler effect limits the maximal spin current in magnetic insulators which have been driven out of equilibrium by magnetic fields. These findings by an international research team present a surprising parallel to what happens in superconductors driven by electric fields and could aid the design of future nano-devices. more

Researchers engineer the first technique to exploit the tunable symmetry of 2D materials for nonlinear optical applications, including laser systems and optical spectroscopy as well as next-generation optical quantum information processing and computing. more

Excitons can simultaneously adopt atomic-like and solid-like characteristics when stimulated by light. The discovery opens up an important new avenue for the manipulation of excitonic as well as materials’ properties by light. more

New switch for nanolight: Team develops a unique platform to program a layered crystal, taking an important step toward the control of nanolight. The work also provides insights for the field of optical quantum information processing. more
