Quantum objects in contrast to conventional macroscopic objects don’t have a specific location and velocity; instead they are smeared out over a certain region, typically the deBroglie wavelength and ...

Superconductivity is a fascinating state of matter in which an electrical current can flow without any resistance. Usually, it can exist in two forms. One is destroyed easily with a magnetic field and ...
