Remarks on coherent states in quantum field theory
Coherent states of the photon field are rigorously described within the framework of a space-time formalism. The given form allows a rigorous...

Spin Waves
The development of our present understanding of ferromagnetism, anti-ferromagnetism, and ferrimagnetism has been characterized by a series of shrewd... -
Feinstrukturuntersuchung
Das Aussehen des Röntgenbeugungsbildes ermöglicht eine Unterscheidung zwischen kristallinen und amorphen1 Stoffen: im ersten Fall treten zahlreiche... -
Multidirectional, multipolarization antennas for scalar and tensor gravitational radiation
Some gravitational radiation antenna designs are discussed which are capable of distinguishing between the spin zero scalar radiation predicted by...

Method of the Neutron-Diffraction Determination of Magnetic Structures
In this section we shall derive an experimental-physicist’s version of all the main formulas determining the elastic coherent scattering of neutrons... -
Magnetic Structure Work at the Nuclear Center of Grenoble
Three structures are briefly reported: FeRh is antiferromagnetic at low temperatures and ferromagnetic above 60°C. Fe has in both region a high...
