Entanglement entropy between real and virtual particles in ϕ 4 quantum field theory
(American Physical Society, 2015-04)
The aim of this work is to compute the entanglement entropy of real and virtual particles by rewriting the generating functional of ϕ4 theory as a mean value between states and observables defined through the correlation ...

Frustating use of the Laplace transform for the quantum states of a particle in a box
(Sociedade Brasileira de Física, 2020-05-29)
In a recent paper diffused in the literature, the quantum problem of a particle in a infinite square well potential was claimed to be solved via Laplace transform. Surprisingly, the correct solutions were found for an ...

Solid particles in the tropical lowest stratosphere
(2007-02-22)
We report in situ and remote observations proving occasional occurrence of solid particles in the tropical lowest stratosphere, 200km from deep convective events. The particles were found during field campaigns in Southeast ...

RELATIVISTIC 3-PARTICLE SCATTERING EQUATIONS
(American Physical Soc, 1993-10-01)
We derive a set of relativistic three-particle scattering equations in the three-particle c.m. frame employing a relativistic three-particle propagator suggested long ago by Ahmadzadeh and Tjon in the c.m. frame of a ...
