In addition, the so-called Fermi resonance, first described almost a century ago in carbon dioxide, occurs at the atomic and molecular level when two vibrational modes caused by the absorption of ...

Electrons can only possess specific energy levels while bound to an atom ... The researchers used the FERMI free electron ...

The coefficient of the linear term is proportional to the effective mass of the quasiparticles, which can be enhanced compared to the bare electron mass due to interactions ... by the density of ...

For many years, physics studies focused on two main types of magnetism, namely ferromagnetism and antiferromagnetism. The ...

If a positive V is applied to the sample, the Fermi level of the sample shifts down with respect to ... the matrix element |M|² can be written as: where m is the electron mass, s is the width of the ...

The situation changes at the surface of a 3D host (or the edge of a 2D host) and new electron states appear at these boundaries. Depending on doping and crystal structure, the Fermi level may ...
