Quantum particles have a social life, of a sort. They interact and form relationships with each other, and one of the most important features of a quantum particle is whether it is an introvert—a ...

Passive, lossy materials with positive index at real frequencies can be used to realize optical antimatter under complex frequency excitation. Our approach enables arbitrary complex \(\epsilon ,\,\mu\ ...

Plasma physics is the study of a state of matter comprising charged particles. Plasmas are usually created by heating a gas until the electrons become detached from their parent atom or molecule. This ...

To enable analytical solution, we need to investigate problems where the deformation gradient tensor is known precisely. We can then substitute it into the formula for stress as a function of the ...
