A New Idea About Why Tiny Particles Tremble

In the paper's words

Zitterbewegung (ZBW) — the trembling motion of Dirac wave packets at the Compton scale, first identified by Breit and Schrödinger — is conventionally explained as interference between positive- and negative-energy branches on the real line. We develop a conjecture, motivated by the adelic physics program, that ZBW is instead (or additionally) the observable signature of mixing between the Archimedean completion Q_∞ = R and the 2-adic completion Q₂ of the rational base field: a packet localized at the real place x_∞ necessarily contains Fourier components delocalized at the 2-adic place x₂, and the observed oscillation at angular frequency ω_ZBW = 2E/ℏ is interpreted as the beat between these sectors. The Majorana reality condition realizes the identification of the two places, and topological protection arises from Ostrowski incommensurability of R and Q₂. [...]

Numbers it reports

No sentence of this paper reports a figure with a unit or a quantity word, so none is shown.

How it is done

1. This paper advances a specific ontological hypothesis, taken from the adelic physics program [9]: the physically accessible base field is $\mathbb{Q}$, not $\mathbb{R}$, and by Ostrowski's theorem all completions of $\mathbb{Q}$ — the real place $\mathbb{R}$ and the $p$-adic places $\mathbb{Q}_{p}$ — are physically meaningful.

2. The statistical-mechanical treatment of the problem of motion in [1] frames ZBW as the central puzzle of the Dirac position operator; the supplied summary is truncated before its later results, so we use it only for this historical framing.

   from 2. Background and Related Work

3. Following the demonstrated controllability of ZBW in synthetic systems [5], [6], [7] and its electrical detectability [8], we propose a simulation in which a discrete dynamics emulating a $p$-adic (ultrametric) position space is coupled to a continuous real-space sector, with a tunable coupling $\Delta$.

What would falsify it

1. We develop a conjecture, motivated by the adelic physics program, that ZBW is instead (or additionally) the observable signature of mixing between the Archimedean completion $\mathbb{Q}_{\infty} = \mathbb{R}$ and the 2-adic completion $\mathbb{Q}_{2}$ of the rational base field: a packet localized at the real place $x_{\infty}$ necessarily contains Fourier components delocalized at the 2-adic place $x_{2}$, and the observed oscillation at angular frequency $\omega_{\mathrm{ZBW}} = 2E/\hbar$ is interpreted as the beat between these sectors.

   from Abstract

2. We state falsifiable tests on emulation platforms and enumerate the framework's failure modes; the framework remains conjectural, and its empirical content currently hinges on an undetermined mixing amplitude $\Delta$.

   from Abstract

3. The choice of the prime $p = 2$ is motivated by the companion program's identification of ZBW as a $\mathbb{Z}_{2}$-valued topological observable distinguishing Dirac from Majorana fermions [11], [12], and by the structural underdetermination of the position operator, which manifests at the Archimedean place as ZBW (the Newton–Wigner no-go) and at $p$-adic places as a discrete Bruhat–Tits observable [10].

   from 1. Introduction

Where the claim stops

1. (a) The restriction to two places $v \in \{\infty, 2\}$ is an assumption; nothing in the product formula (Derivation 2) singles out $p = 2$ algebraically, since $\prod_{v}|q|_{v} = 1$ holds for every rational $q$ and every prime.

   from 6. Discussion

2. (c) The mixing amplitude $\Delta$ is a free parameter; until an independent determination or bound exists, every mixed-channel number is a projection with unbounded uncertainty, as stated in Results item 6.

   from 6. Discussion

3. (d) The claim that FW transformations cannot act on $\mathcal{H}_{2}$ rests on the tensor-product factorization $\mathcal{H} = \mathcal{H}_{\infty} \otimes \mathcal{H}_{2}$, which is itself part of the conjecture; if the adelic Hilbert space does not factor, Derivation 5 fails.
