Some of our results for the hydrogen atom in parallel electric and magnetic fields [39] are shown in Table 4. 

In the Stark effect the whole real energy axis is the continuum spectrum and no threshold exists in the unrotated Hamiltonian for the continuous spectmm to rotate about. The Hamiltonian for the hydrogen atom in parallel electric and magnetic fields, after the above complex transformation has been applied, becomes...

We first consider the electric vectors to be parallel to the plane of incidence. The tangential components of the electric and magnetic fields are required to be continuous across the boundary ... 

Besides its appearance in the FFMF equation in plasma physics, as well as associated with time-harmonic fields in chiral media, the chiral Beltrami vector field reveals itself in theoretical models for classical transverse electromagnetic (TEM) waves. Specifically, the existence of a general class of TEM waves has been advanced in which the electric and magnetic field vectors are parallel [59]. Interestingly, it was found that for one representation of this wave type, the magnetic vector potential (A) satisfies a Beltrami equation ... 

Reflection at a surface of a beam of linearly polarized photons alters the direction and amplitude of the electric and magnetic vectors. It is these differences between incident and reflected beams that give information concerning surface structure, as they depend on the interaction of the beam with the electronic distribution and with the associated local electric and magnetic fields on the surface. The phase and amplitude change for the vectors is different for the component parallel to the plane of incidence than for the component perpendicular to it. The result is a vector that follows a spiral during its propagation, and is referred to as elliptically polarized, Fig. 12.2. A deeper treatment of these optical properties can be found in Ref. 9. Such measurements are referred to as specular reflectance. 

In the presence of a strong external electric field, E, the molecular dipoles of a polar fluid acquire a small average orientation parallel to the applied field. When the electric and magnetic fields are parallel the l4N NMR signal of a pure polar liquid is split by AV... 

Nematic liquid crystals are also oriented with their long axes parallel, but they are not separated into layers, and they behave like toothpicks in a box, maintaining their orientation but free to move in any direction. Nematic substances can be aligned by electric and magnetic fields, resulting in a number of characteristics such as the ability in some cases to be electrically switched from clear to opaque. This property gives rise to many technical applications such as in display systems.
