论文摘要
一维量子系统的静态和动力学特性,由所谓的Hatano-Nelson型的非热汉尔顿人描述;研究了具有不对称(或非重生)跳跃的紧密结合模型。该模型的静态特性已经进行了大量研究。复杂的频谱,皮肤效应及其拓扑解释等。疾病和颗粒间相互作用的影响,尤其是当它们共存时,可能就不太了解。在这里,我们还将重点关注其动力学特性,并在波包和纠缠(熵)动力学中揭示一些独特的特征。为此,显示了一些基于改进的数字基于改进的结果(使用此系统较大的系统尺寸$ L $可以访问)。
The static and dynamical properties of a one-dimensional quantum system described by a non-Hermitian Hamiltonian of the so-called Hatano-Nelson type; a tight-binding model with asymmetric (or non-reciprocal) hopping, are studied. The static properties of the model have been much studied; the complex spectrum, skin effect and its topological interpretation, etc. Effects of disorder and inter-particle interaction, especially, when they coexist, may be less understood. Here, we will also focus on its dynamical properties and reveal some unique features in the wave-packet and entanglement (entropy) dynamics. For that some latest (original) results based on improved numerics (with this a system of larger system size $L$ becomes accessible) are shown.
