For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

Magnetic invisibility sounds simple in theory. Place the right materials around an object and magnetic fields flow around it as if nothing were there. Reality has been far messier. For nearly two ...

Electrons in a magnetic field can display striking behaviors, from the formation of discrete energy levels to the quantum Hall effect. These discoveries have shaped our understanding of quantum ...
