Relativistically extended Blanchard recurrence relation for hydrogenic matrix elements
R. P. Martínez-y-Romero, H. N. Núñez-Yépez, A. L. Salas-Brito
General recurrence relations for arbitrary non-diagonal, radial hydrogenic matrix elements are derived in Dirac relativistic quantum mechanics. Our approach is based on a generaliz…

Limitations on the superposition principle: superselection rules in non-relativistic quantum mechanics
C. Cisneros, R. P. Martínez-y-Romero, H. N. Nuñez-Yepez +1
The superposition principle is a very basic ingredient of quantum theory. What may come as a surprise to many students, and even to many practitioners of the quantum craft, is tha…
