The $p$-adic Jaynes-Cummings model in symplectic geometry

TL;DR

This paper explores the properties of a $p$-adic version of the classical Jaynes-Cummings model within symplectic geometry, revealing how the model's structure varies with different prime values of $p$.

Contribution

It introduces the $p$-adic Jaynes-Cummings model and analyzes its symplectic geometric properties, highlighting prime-dependent structural differences.

Findings

Model structure varies with prime $p$ modulo 4

Special treatment needed for $p=2$ case

Provides foundational understanding of $p$-adic integrable systems

Abstract

The notion of classical $p$-adic integrable system on a $p$-adic symplectic manifold was proposed by Voevodsky, Warren and the second author a decade ago in analogy with the real case. In the present paper we introduce and study, from the viewpoint of symplectic geometry and topology, the basic properties of the $p$-adic version of the classical Jaynes-Cummings model. The Jaynes-Cummings model is a fundamental example of integrable system going back to the work of Jaynes and Cummings in the 1960s, and which applies to many physical situations, for instance in quantum optics and quantum information theory. Several of our results depend on the value of $p$: the structure of the model depends on the class of the prime $p$ modulo $4$ and $p=2$ requires special treatment.
