The Coloumb drag is a phenomenon that affects two electronic circuits, whereby a charge current in one circuit induces a responsive current in a neighboring circuit solely through so-called Coloumb interactions. These are ...
Topological materials that possess certain atomic-level symmetries, including topological insulators and topological semi-metals, have elicited fascination among many condensed matter scientists because of their complex electronic ...

To create efficient energy storage solutions and actuators, engineers need materials with a high dielectric constant. The dielectric constant is essentially the ratio of a substance's permittivity (i.e., its ability to store ...
Professor Alexander Szameit and his group of physicists from the University of Rostock, in collaboration with Professor Stefano Longhi from the Polytechnic University of Milan, discovered a novel and paradoxical behavior ...
