论文摘要
为了描述手性磁效应，引入了手性化学势$μ_5$，以模仿夸克 - 胶原等离子体在外部磁场影响下拓扑电荷变化的影响。我们采用（1+1）尺寸Nambu-Jona-Lasinio（NJL）模型来研究量子模拟器中有限的手性化学势$μ_5$的手性相结构和手性电荷密度。通过执行量子假想的时间演化（QITE）算法，我们在各种温度$ t $和化学势$ $ $，$μ_5$下模拟（1+1）维数NJL模型，并发现量子模拟与分析量及其分析量及其分析量以及与lattice hamililton and lattice hamililton ianian的垂直化相吻合。
To describe the chiral magnetic effect, the chiral chemical potential $μ_5$ is introduced to imitate the impact of topological charge changing transitions in the quark-gluon plasma under the influence of an external magnetic field. We employ the (1+1) dimensional Nambu-Jona-Lasinio (NJL) model to study the chiral phase structure and chirality charge density of strongly interacting matter with finite chiral chemical potential $μ_5$ in a quantum simulator. By performing the Quantum imaginary time evolution (QITE) algorithm, we simulate the (1+1) dimensional NJL model on the lattice at various temperature $T$ and chemical potentials $μ$, $μ_5$ and find that the quantum simulations are in good agreement with analytical calculations as well as exact diagonalization of the lattice Hamiltonian.
