Fermion-doubling problem in Chiral discretizations of Quantum field theory: Definitive proof, Fixing, and Computation of two-point correlation function
Dogukan Bakircioglu, Pablo Arnault
The paper provides a rigorous proof that the Dirac quantum cellular automaton suffers from fermion doubling (though less severely than standard lattice gauge theories), derives its…

Fermion Doubling in Quantum Cellular Automata
Dogukan Bakircioglu, Pablo Arnault, Pablo Arrighi
A Quantum Cellular Automaton (QCA) is essentially an operator driving the evolution of particles on a lattice, through local unitaries. Because , QCAs constitute a…

Canonical quantization of the complex scalar field without making use of its real and imaginary parts
Pablo Arnault
We proceed to the canonical quantization of the complex scalar field without making use of its real and imaginary parts. Our motivation is to formally connect, as tightly as possib…
