Time Quantum

The recent suggestion that late time quantum dynamics may be important for resolving cosmological issues associated with our observed universe requires a consideration of several subtle issues associated with quantum cosmology, as we describe here. The resolution of these issues will be important if we are to be able to properly ascribe probability measures associated with eternal inflation, and a string landscape.

Time Quantum

We show the relation between the Heisenberg averaging of regularized 2-point out-of-time ordered correlation function and the 2-point spectral form factor in bosonic quantum mechanics. The generalization to all even-point is also discussed. We also do the direct extension from the bosonic quantum mechanics to the noninteracting scalar field theory. Finally, we find that the coherent state and large-[Formula: see text] approaches are useful in the late-time study. We find that the computation of the coherent state can be simplified by the Heisenberg averaging. Therefore, this provides a simplified way to probe the late-time quantum chaos through a coherent state. The large-[Formula: see text] result is also comparable to the [Formula: see text] numerical result in the large-[Formula: see text] quantum mechanics. This can justify that large-[Formula: see text] technique in bosonic quantum mechanics can probe the late time, not the early time. Because the quantitative behavior of large-[Formula: see text] can be captured from the [Formula: see text] numerical result, the realization in experiments should be possible.

Temporal Modes

We study the problems of time consciousness from the standpoint of philosophy, physics and psychology; it is argued that such a sequence in the analysis of the problem allows us to reveal the actual psychological aspect of the problem of the objectivity of the consciousness of time, which is the goal of the study. Both the philosophical concepts of the time consciousness of I. Kant, E. Husserl and F. Brentano, and the physical theories of the study of time (quantum physics, cosmology, the physics of non-equilibrium processes) are analyzed. It has been established that in philosophical theories, the concepts: consciousness, memory, perception, representation, and others do not have clear definitions and can change their meaning depending on the context. It is emphasized that in physical and human sciences time is investigated, as a rule, in connection with the concept of “space”. It is shown that when analyzing the problem of the consciousness of time, one should first decide on the concept of “reality”, which allows us to remove contradictions in the understanding of time in various physical theories. It is concluded that the existence of both objective and subjective time can only be spoken when we operate with concepts; outside of this the concept of “time” has meaning only when a person is considered as part of society. It is shown that in relation to the collective and personal unconscious, the temporal modes of the "past", "present" and "future" do not make sense, since "the whole diversity of everything" is represented in the unconscious field simultaneously and extra-spatially.
