Physicists are familiar with persistent currents in superconductors – in which electrons can flow forever, unhindered by resistance. But even the best normal conductors such as copper or gold have ...

A river erodes its course. In an electric circuit, does the wiring get eroded by the current, atoms, electrons etc? — Bill "It's a reasonable analogy to think of an electric current acting like ...

Electrons in graphene can act like a perfect fluid, defying established physical laws. This finding advances both fundamental ...

In a circuit connected to a battery, the electrons are the charge carrier and flow from the battery’s negative terminal, around the circuit and back to the positive terminal.

Researchers from the Indian Institute of Science’s Department of Physics, together with researchers from Japan's National ...

When atom clouds go with the flow Time to retire the old soldering iron? In the "atomtronic" circuits pictured on the right, it is atoms, not electrons, that flow. Such circuits could form the ...

Graphene is a single-atomic carbon sheet with a hexagonal honeycomb network. Electrons in graphene take a special electronic state called Dirac-cone where they behave as if they have no mass. This ...

In a normal electric circuit, say the wiring in your house, electrons bump and jostle each other and the surrounding atoms as they flow. That wastes some energy, which leaves the circuit as heat.

Today's lithium-ion chargers start out pumping electrons into a discharged battery at whatever level the plugs or circuit breakers allow.

In their simulations of 2D semiconductors with strong electron-phonon interactions, the researchers found that when treating both the charge and heat carriers as part of the same system, the ...
