Quantum dissection of a covalent bond with the entanglement
... There are many interesting properties of the C2 molecule that can be determined from the entanglement spectrum. To address recent VB studies, we are concerned specifically with the possibilities of anti-ferromagnetic correlations5, 11 , which are described as an increase in probability of electrons ...

Renormalisation of Noncommutative Quantum Field Theory
... Since classical field theories can be geometrically described, it is not difficult to write down classical action functionals on noncommutative spaces. The first example of this type was Yang-Mills theory on the noncommutative torus. Another example is the noncommutative geometrical description of t ...
