Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a ...

The nonlinear Hall signal shows a sharp peak when the first moiré valence band is half-filled (Filling = 0.5 shown in the left figure). The corresponding generation efficiency is at least two orders ...

A team of researchers at Nagoya University has discovered something surprising. If you have two tiny vibrating elements, each one barely moving on its own, and you combine them in the right way, their ...

The literature on optimal monetary policy typically makes three major assumptions: (1) policymakers’ preferences are quadratic, (2) the economy is linear, and (3) stochastic shocks and policymakers’ ...
