Lombardi and M. Castagnino, Stud. Hist. Philos. Mod. Phys 39, No.2, 380–443 (2008); J. Phys, Conf. Ser. 128, 012014 (2008)]. Through the assumption that in quantum field theory the Casimir operators of the Poincar´e group actualize, the nonrelativistic limit of the latter group yields to the actualization of the Casimir operators of the Galilei group, which is in agreement with the actualization rule of previous versions of modal Hamiltonian interpretationengjournal articlehttps//doi.org/10.1063/1.3243822http://jmp.aip.org/resource/1/jmapaq/v50/i10/p103526_s1open access530.145Casimir effectQuantum field theoryTeoría de los quanta2210.23 Teoría Cuántica
