Fully quantum perturbative description of correlated Stokes--anti-Stokes scattering
Raul Corrêa, Marcelo F. Santos, Carlos H. Monken +1
The process in which Raman scattering produces correlated Stokes and anti-Stokes radiation is known as Stokes--anti-Stokes (SaS) scattering. It has been shown recently that this pr…
Bell and Mermin inequalities in Quantum Field Theory from vacuum projectors and Weyl operators
M. S. Guimaraes, I. Roditi, S. P. Sorella +1
The use of the vacuum projector and of the unitary Weyl operators enables us to construct a set of Hermitian dichotomic operators in relativistic scalar Qu…
Oscillators with imaginary coupling: spectral functions in quantum mechanics and quantum field theory
Bruno W. Mintz, Itai Y. Pinheiro, Rui Aquino
The axioms of Quantum Mechanics require that the hamiltonian of any closed system is self-adjoint, so that energy levels are real and time evolution preserves probability. On the o…
Bell-CHSH inequality and unitary transformations in Quantum Field Theory
D. O. R. Azevedo, F. M. Guedes, M. S. Guimaraes +3
Unitary transformations are employed to enhance the violations of the Bell-CHSH inequality in relativistic Quantum Field Theory. The case of the scalar field in Minkowski spa…
Bell's inequality in relativistic Quantum Field Theory
M. S. Guimaraes, I. Roditi, S. P. Sorella
A concise and self-contained introduction to the Bell inequality in relativistic Quantum Field Theory is presented. Taking the example of a real scalar massive field, the violation…
Introduction to Bell's inequality in Quantum Mechanics
M. S. Guimaraes, I. Roditi, S. P. Sorella
A pedagogical introduction to Bell's inequality in Quantum Mechanics is presented. Several examples, ranging from spin to coherent and squeezed states are worked out. The gen…
