Using an advanced Monte Carlo method, Caltech researchers found a way to tame the infinite complexity of Feynman diagrams and solve the long-standing polaron problem, unlocking deeper understanding of ...

A new electrical method to conveniently change the direction of electron flow in some quantum materials could have implications for the development of next-generation electronic devices and quantum ...

Coulomb blockade is a phenomenon in which the flow of electrons through a nanostructure, such as a quantum dot or a single-electron transistor, is restricted due to the electrostatic repulsion between ...

Brain lesions beset with smoldering inflammation, and myeloid cells around their edges, define multiple sclerosis. This might be due, in part, to the flipping of electron flow within microglia, ...

A condition long considered to be unfavorable to electrical conduction in semiconductor materials may actually be beneficial in 2D semiconductors, according to new findings by UC Santa Barbara ...

What is a Single-Electron Transistor? A single-electron transistor (SET) is a nanoscale electronic device that allows the precise control of individual electrons. Unlike conventional transistors that ...

In collaboration with scientists in Germany, EPFL researchers have demonstrated that the spiral geometry of tiny, twisted ...

For years, scientists have known that phonons (vibrations of atoms) carry heat through solids. However, when two different materials come in contact, like in a computer chip, these vibrations often ...

Speeding up chemical reactions is key to improving industrial processes or mitigating unwanted or harmful waste. Realizing these improvements requires that chemists design around documented reaction ...

A new method by Penn State researchers conveniently changes the direction of electron flow in materials that exhibit the quantum anomalous Hall (QAH) effect — a phenomenon in which the flow of ...
