Abstract

In this paper, we investigate a new class of [Formula: see text]-deformed [Formula: see text] backgrounds produced by classical [Formula: see text]-matrices that satisfy the modified classical Yang–Baxter equation [JHEP 03, 094 (2022)]. We consider the string sigma model on [Formula: see text]-deformed [Formula: see text] background. We numerically examined the classical phase space dynamics of these (semi)classical strings over this deformed background and computed several chaos indicators. These involve figuring out the Poincaré section and computing the Lyapunov exponents. In the (semi)classical limit, we discover evidence that supports a non-integrable phase space dynamics.

玻色子η-变形的混沌弦动力学AdS5×T1,1背景

在本文中，我们研究了一类新的[公式:见文]-变形[公式:见文]背景产生的经典[公式:见文]-矩阵，满足修正的经典Yang-Baxter方程[JHEP 03, 094(2022)]。我们考虑在[公式:见文]-变形[公式:见文]背景下的弦σ模型。我们用数值方法研究了这些(半)经典弦在这种变形背景下的经典相空间动力学，并计算了几个混沌指标。这包括计算庞加莱剖面和计算李亚普诺夫指数。在(半)经典极限下，我们发现了支持不可积相空间动力学的证据。
