Response functions are a fundamental aspect of physics; they represent the link between experimental observations and the underlying quantum many-body state. However, this link is often ...
Most experiments on condensed matter and cold atom systems measure how an observable changes after perturbing the system. Linear response theory is crucial for interpretation of these experiments, ...
Low-friction, high-stiffness ball guides support on one rail (top) or two (bottom). The trade-offs for this performance are higher cost and more noise. The shortest path between two points is a ...
