Entropic Time

TL;DR

This paper explores entropic time within quantum mechanics, presenting it as a novel framework that naturally distinguishes past from future and tracks the accumulation of changes, offering new insights into the nature of time.

Contribution

It introduces the concept of entropic time as a new approach to understanding temporal evolution in quantum mechanics, emphasizing its distinction from traditional notions of time.

Findings

Entropic time provides a natural distinction between past and future.

It serves as a bookkeeping device for tracking changes in quantum systems.

The framework offers new perspectives on the role of time in fundamental physics.

Abstract

The formulation of quantum mechanics within the framework of entropic dynamics includes several new elements. In this paper we concentrate on one of them: the implications for the theory of time. Entropic time is introduced as a book-keeping device to keep track of the accumulation of changes. One new feature is that, unlike other concepts of time appearing in the so-called fundamental laws of physics, entropic time incorporates a natural distinction between past and future.
