I am looking for a paper written by Massimo Blasone

[Heidi]

Hi Pf
I read several years ago an article written by Massimo Blasone. He wrote that quantum physics has a much logical description when it uses two fields one forward time and the other backward or something like that.
I forgot in which paper . Did you read it?
thanks

No, but it reminds me of the thermo field approach to quantum field theory.

Yes it was in a text about thermo field theory. He took a doubling of the degrees of freedom of the phase space.
thanks.

I found it:

I had a question about it.
the two currents seem to be on equal footing, so what does happen it there is a one-way mirror on the back trajectory? interferences or not in this model?

Does thermo field theory better explain or predict new results?

Thermo field theory is one formulation of non-equilibrium quantum many-body theory. It also takes into account quantum interference.
