Scientists have demonstrated for the first time that interlayer coupling in a van der Waals (vdW) material can be largely modulated by a protonic gate, 'injecting' protons into the device. The same ...

The exchange of energy and environment is inevitable in any physical system, so non-Hermitian systems that can be described by non-Hermitian Hamiltonians are ubiquitous. There are two kinds of ...

A RMIT-led international collaboration published this week has observed, for the first time, electric gate-controlled exchange-bias effect in van der Waals (vdW) heterostructures, offering a promising ...

The exchange-bias (EB) effect, which originates from interlayer magnetic coupling, has played a significant role in fundamental magnetics and spintronics since its discovery. Although manipulating the ...

Physicists have succeeded in coupling different types of electron-hole pairs (excitons) in the van der Waals material molybdenum disulfide. This successful coupling allows them to utilize and control ...

(Nanowerk News) In every physical system, energy and environment interact, which is why non-Hermitian systems are common. In the context of physics and engineering, a "non-Hermitian system" refers to ...
