The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, ...

This is a preview. Log in through your library . Abstract The single-particle spectral function measures the density of electronic states in a material as a function of both momentum and energy, ...

Consider the following physics problem. An object with a mass of 1 kg and a velocity of 1 m/s in the x-direction has a net force of 1 Newton pushing on it (also in the x-direction). What will the ...

Marten Patt studied physics at RWTH Aachen University, and finished his diploma thesis on time- and laterally-resolved spin polarization in semiconductors in 2009. He then joined the group of Claus ...

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 ...

Topological materials are a class of materials that exhibit unique electronic properties at their boundary (surface in 3D materials; edge in 2D materials) that are robust against imperfections or ...
