Paper
- Could random dynamics derive quantum mechanics via the weak value?
Holger Bech Nielsen; Keiichi Nagao, Last, University of Ljubljana, Faculty of Mathematics and Physics
Bled Workshops in Physics (Proceedings to the 27th workshop "What Comes Beyond the Standard Models", Bled, Slovenia, Jul.8-17, 2024), Dec. 2024, [Reviewed] - Automatic hermiticity for mixed states
Keiichi Nagao; Holger Bech Nielsen, Lead, We previously proposed a mechanism to effectively obtain, after a long time development, a Hamiltonian being Hermitian with regard to a modified inner product $I_Q$ that makes a given non-normal Hamiltonian normal by using an appropriately chosen Hermitian operator $Q$. ,We studied it for pure states. In this letter we show that a similar mechanism also works for mixed states by introducing density matrices to describe them and investigating their properties explicitly both in the future-not-included and future-included theories. ,In particular, in the latter, where not only a past state at the initial time $T_A$ but also a future state at the final time $T_B$ is given, we study a couple of candidates for it, and introduce a ``skew density matrix'' composed of both ensembles of the future and past states such that the trace of the product of it and an operator ${\cal O}$ matches a normalized matrix element of ${\cal O}$. ,We argue that the skew density matrix defined with $I_Q$ at the present time $t$ for large $T_B-t$ and large $t-T_A$ approximately corresponds to another density matrix composed of only an ensemble of past states and defined with ,another inner product $I_{Q_J}$ for large $t-T_A$., Oxford University Press (The Physical Society of Japan)
Progress of Theoretical and Experimental Physics, 16 Feb. 2023, [Reviewed] - What gives a “theory of Initial Conditions” ?
Holger Bech Nielsen; Keiichi Nagao, Last, 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 Hamiltonian functions by determining the actual solution to the equations of motion, that should be realized; this means it predicts the initial conditions. It should be stressed that a major result of ours is that the effective equations of motion will in practice - after long time - be so accurately as if we had indeed a Hermitian Hamiltonian,,and so there is at first nothing wrong in assuming a non-Hermitian one. In fact it would practically seem Hermitian anyway. A major new point is that we seek by a bit intuitively arguing to suggest some cosmologically predictions from the mentioned initial conditions predicted: We seek even by assuming essentially nothing but very general properties of the non-Hermitian Hamiltonian that we in practice should find a bottom in the (effective Hermitian) Hamiltonian and that the Universe at some moment should pass through a (multiple) saddle point very closely, so that the time spent at it would be very long., DMFA
Bled Workshops in Physics ,(Proceedings to the 25th workshop "What Comes Beyond the Standard Models", Bled, Slovenia, Jul.4-10, 2022), Dec. 2022, [Reviewed] - Reality from maximizing overlap in the periodic complex action theory
Keiichi Nagao; Holger Bech Nielsen, Lead, Abstract
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, and extend a normalized matrix element of an operator $\hat{\mathcal {O } }$, which is called weak value in the real action theory, to another expression $\langle \hat{\mathcal {O } } \rangle _{\mathrm{periodic}~\mathrm{time } }$. We present two theorems stating that $\langle \hat{\mathcal {O } } \rangle _{\mathrm{periodic}~\mathrm{time } }$ becomes real for $\hat{\mathcal {O } }$ being Hermitian with regard to a modified inner product that makes a given non-normal Hamiltonian $\hat{H}$ normal. The first theorem holds for a given period tp in a case where the number of eigenstates having the maximal imaginary part B of the eigenvalues of $\hat{H}$ is just one, while the second one stands for tp’s selected such that the absolute value of the transition amplitude is maximized in a case where B ≤ 0 and |B| is much smaller than the distances between any two real parts of the eigenvalues of $\hat{H}$. The latter proven via a number-theoretical argument suggests that, if our universe is periodic, then even the period could be an adjustment parameter to be determined in the Feynman path integral. This is a variant type of the maximization principle that we previously proposed., Oxford University Press (OUP)
Progress of Theoretical and Experimental Physics, 23 Jul. 2022, [Reviewed] - Formalism of a harmonic oscillator in the future-included complex action theory
Keiichi Nagao and Holger Bech Nielsen, Lead, 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 $\hat{H}$, in which a mass $m$ and an angular frequency $\omega$ are taken to be complex numbers. In order for the model to be sensible some restrictions on $m$ and $\omega$ are required. We draw a phase diagram in the plane of the arguments of $m$ and $\omega$, according to which the model is classified into several types. ,In addition, we formulate two pairs of annihilation and creation operators, two series of eigenstates of the Hamiltonians $\hat{H}$ and $\hat{H}^\dag$, and coherent states. They are normalized in a modified inner product $I_Q$, with respect to which ,the Hamiltonian $\hat{H}$ becomes normal. Furthermore, applying to the model the maximization principle that we previously proposed, we obtain an effective theory described by a Hamiltonian that is $Q$-Hermitian, i.e. Hermitian with respect to the modified inner product $I_Q$. The generic solution to the model is found to be the ``ground'' state. Finally we discuss what the solution implies., Oxford University Press (The Physical Society of Japan)

Progress of Theoretical and Experimental Physics, 15 Feb. 2018, [Reviewed] - Reality from maximizing overlap in the future-included theories
Keiichi Nagao and Holger Bech Nielsen, Lead, 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 of an operator $\hat{\cal O}$, ,which is defined in terms of the future and past states ,with a proper inner product $I_Q$ that makes a given Hamiltonian normal. ,The theorem states that, ,provided that the operator $\hat{\cal O}$ is $Q$-Hermitian, i.e. ,Hermitian with regard to the proper inner product $I_Q$, ,the normalized matrix element ,becomes real and time-develops under ,a $Q$-Hermitian Hamiltonian ,for the past and future states selected such that ,the absolute value of the transition amplitude from ,the past state to the future state is maximized. ,Discussing what the theorem implicates, we speculate that ,the future-included complex action theory ,would be the most elegant quantum theory., DMFA

Progress of Theoretical and Experimental Physics, 2013, [Reviewed] - Correspondence between future-included and future-not-included theories
Keiichi Nagao and Holger Bech Nielsen, Lead, We briefly review the correspondence principle proposed in our previous paper, which claims that if we regard a matrix element defined in terms of the future state at time $T_B$ and the past state at time $T_A$ as an expectation value in the complex action theory whose path runs over not only past but also future, the expectation value at the present time $t$ of a future-included theory for large $T_B-t$ and large $t-T_A$ corresponds to that of a future-not-included theory with a proper inner product for large $t-T_A$. This correspondence principle suggests that the future-included theory is not excluded phenomenologically.

H.B.Nielsen; N.S.Mankoc Borstnik; K.Nagao; G.Moultaka, The purpose of this discussion contribution is to suggest the possibility that the imaginary action model could function as a cut off in loop diagrams. We argue also that the complex action model of M.Ninomiya and H.B.Nielsen has the De Broglie-Bohm particle appearing by itself, which is in a way already present in the contribution to this conference.
