Reconstruction of Quantum Fields: CCR, CAR and Transfields
Nicolás Medina Sánchez, Borivoje Dakić
One of the traditional ways of introducing bosons and fermions is through creation-annihilation algebras. Historically, these have been associated with emission and absorption proc…
The classical limit of quantum mechanics through coarse-grained measurements
Fatemeh Bibak, Carlo Cepollaro, Nicolás Medina Sánchez +2
Understanding how classical physics emerges from quantum mechanics remains a central problem in the foundations of physics. Here we derive a classical limit from finite-resolution…
Reconstruction of Quantum Particle Statistics: Bosons, Fermions, and Transtatistics
Nicolás Medina Sánchez, Borivoje Dakić
Identical quantum particles exhibit only two types of statistics: bosonic and fermionic. Theoretically, this restriction is commonly established through the symmetrization postulat…
