Physicists watch light drift in quantized steps for the first time

In physics, the classical "Hall effect," discovered in the late 19th century, describes how a transverse voltage is generated ...

Alloy-engineered valleytronics: Microscopic mechanism gives scientists precise control over how excitons behave

Scientists have observed a new microscopic mechanism enabling precise control of the magneto-optical properties of excitons in alloys of two-dimensional semiconductors. This discovery opens up ...

A superfluid freezes and breaks the rules of physics

Physicists have watched a quantum fluid do something once thought almost impossible: stop moving. In experiments with ultra-thin graphene, researchers observed a superfluid—normally defined by its ...

Online Identification of PEMFC Polarization Curves With Nonlinear Concentration Loss

Abstract: Polarization curve plays a significant role in proton exchange membrane fuel cells (PEMFCs) monitoring and control. However, the classical semiempirical model of polarization curve is ...
