Could random dynamics derive quantum mechanics via the weak value?
Holger Bech Nielsen, Keiichi Nagao
We argue that we could make a scenario of deriving quantum mechanics, as a random dynamics project, in the sense of it being almost unavoidable. The basic idea is based on the weak…
What gives a "theory of Initial Conditions" ?
Holger Bech Nielsen, Keiichi Nagao
The present work contains a review of some of the work we have done on complex action or non-Hermitian Hamiltonian theory, especially the result that the anti-Hermitian part of the…
Reality from maximizing overlap in the periodic complex action theory
Keiichi Nagao, Holger Bech Nielsen
We study the periodic complex action theory (CAT) by imposing a periodic condition in the future-included CAT where the time integration is performed from the past to the future, a…
Formalism of a harmonic oscillator in the future-included complex action theory
Keiichi Nagao, Holger Bech Nielsen
In a special representation of complex action theory that we call ``future-included'', we study a harmonic oscillator model defined with a non-normal Hamiltonian , in whic…
Reality from maximizing overlap in the future-included theories
Keiichi Nagao, Holger Bech Nielsen
In the future-included complex and real action theories whose paths run over not only the past but also the future, we briefly review the theorem on the normalized matrix element o…
Complex action suggests future-included theory
Keiichi Nagao, Holger Bech Nielsen
In quantum theory its action is usually taken to be real, but we can consider another theory whose action is complex. In addition, in the Feynman path integral, the time integratio…
