论文摘要

在这项工作中,提出和分析了两级伪 - 热系统的经典量词对应关系。我们表明,如果有合适的规范转换将其与真实场联系起来,则可以用伪 - 温米特型哈密顿量来描述复杂的外部场的存在。我们构建了一个协变量量化方案,该方案将规范相关的伪经典理论映射到单位等效的量子实现,以便在不同的希尔伯特空间之间存在唯一的度量诱导等轴测图。在这种情况下,操作员的伪热条件会引起一种互动,即使对于复杂的场情况,也可以保证相应符号的现实。我们通过构建经典对应关系来分配在复杂场的存在下的物理含义。作为我们的理论框架的应用,我们提出了一个阻尼版本的Rabi问题,并确定了完全抑制阻尼的设置参数的配置。在特定情况下研究了该提案的实验可行性。我们建议在本工作中产生的主要理论结果可以进行实验验证。

In this work, a classical-quantum correspondence for two-level pseudo-Hermitian systems is proposed and analyzed. We show that the presence of a complex external field can be described by a pseudo-Hermitian Hamiltonian if there is a suitable canonical transformation that links it to a real field. We construct a covariant quantization scheme which maps canonically related pseudoclassical theories to unitarily equivalent quantum realizations, such that there is a unique metric-inducing isometry between the distinct Hilbert spaces. In this setting, the pseudo-Hermiticity condition for the operators induces an involution which guarantees the reality of the corresponding symbols, even for the complex field case. We assign a physical meaning for the dynamics in the presence of a complex field by constructing a classical correspondence. As an application of our theoretical framework, we propose a damped version of the Rabi problem and determine the configuration of the parameters of the setup for which damping is completely suppressed. The experimental viability of the proposal is studied within a specific context. We suggest that the main theoretical results developed in the present work could be experimentally verified.
