Representations of the symmetry groups of infinite crystals
Bachir Bekka, Christian Brouder
We investigate the representations of the symmetry groups of infinite crystals. Crystal symmetries are usually described as the finite symmetry group of a finite crystal with perio…
Angular dependence and powder average of resonant inelastic X-ray scattering
Myrtille O. J. Y Hunault, Timothy G. Burrow, Fabien Besnard +2
Resonant Inelastic X-ray scattering (RIXS) is a synchrotron-based spectroscopy that has seen growing interest across a range of scientific disciplines beyond fundamental physics. T…
General expressions for Stevens and Racah operator equivalents
Octave Duros, Amélie Juhin, Hebatalla Elnaggar +2
Several definitions of the crystal field have been used over time and their variety has lead to many misunderstandings, in both theoretical and experimental literature. Two categor…
Quantum groups and quantum field theory: I. The free scalar field
Christian Brouder, Robert Oeckl
The quantum field algebra of real scalar fields is shown to be an example of infinite dimensional quantum group. The underlying Hopf algebra is the symmetric algebra S(V) and the p…
