Resonant tunneling: A possible way to probe the minimum length using atomic systems
A research team led by Prof. Dr. Yang Yong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has revealed a remarkable quantum tunneling phenomenon across double potential barriers. They found that quantum tunneling is.....»»
Scientists reveal how light behaves in formless solids
For a long time, it was thought that amorphous solids do not selectively absorb light because of their disordered atomic structure. However, a new uOttawa study disproves this theory and shows that amorphous solids actually exhibit dichroism, meaning.....»»
AI technique "decodes" microscope images, overcoming fundamental limit
Atomic force microscopy, or AFM, is a widely used technique that can quantitatively map material surfaces in three dimensions, but its accuracy is limited by the size of the microscope's probe. A new AI technique overcomes this limitation and allows.....»»
