By measuring a linear response function directly, such as the dynamic susceptibility, one
can understand fundamental material properties. However, a fresh perspective can be …

With the introduction of x-ray free electron laser sources around the world, new scientific

We elucidate a bias-free light-induced orbital and spin current through nonlinear response
theory, which generalizes the well-known bulk photovoltaic effect in centrosymmetric broken …
