Generalized generating functional for mixed-representation Green's functions: A quantum mechanical approach
Massimo Blasone, Petr Jizba, Luca Smaldone
When one tries to take into account the non-trivial vacuum structure of Quantum Field Theory, the standard functional-integral tools such as generating functionals or transitional…
Non-thermal signature of the Unruh effect in field mixing
Massimo Blasone, Gaetano Lambiase, Giuseppe Gaetano Luciano
Mixing transformations for a uniformly accelerated observer (Rindler observer) are analyzed within the quantum field theory framework as a basis for investigating gravitational eff…
Functional integrals and inequivalent representations in Quantum Field Theory
Massimo Blasone, Petr Jizba, Luca Smaldone
We discuss canonical transformations in Quantum Field Theory in the framework of the functional-integral approach. In contrast with ordinary Quantum Mechanics, canonical transforma…
