手征布朗包络的谱和强度统计

Spectral and Strength Statistics of Chiral Brownian Ensemble

Pragya Shukla

摘要:

多参数手征随机矩阵系综是分析具有手征对称性的一般复杂系统统计行为的重要工具。最近的研究\cite{psmulti}前者映射到手征布朗系综(Ch-BE),出现作为一个非平衡态的一个单一的参数之间的交叉两个固定的手征厄米特系综。这促使我们追求一个详细的统计调查的光谱和强度波动的Ch-BE,重点是他们的行为接近零能量区域。这些信息可以用于广泛的具有手征对称性的复杂系统。我们的分析还揭示了连接的Ch-BE广义Calogero萨瑟兰哈密顿(CSH)和Wishart合奏。这与已知的没有手性的复杂系统与CSH的连接一起强烈地暗示了后者是控制复杂系统的光谱动力学的“骨干”哈密顿量。

英文摘要:

Multi-parametric chiral random matrix ensembles are important tools to analyze the statistical behavior of generic complex systems with chiral symmetry. A recent study \cite{psmulti} of the former maps them to the chiral Brownian ensemble (Ch-BE) that appears as a non-equilibrium state of a single parametric crossover between two stationary chiral Hermitian ensembles. This motivates us to pursue a detailed statistical investigation of the spectral and strength fluctuations of the Ch-BE, with a focus on their behavior near zero energy region. The information can then be used for a wide range of complex systems with chiral symmetry. Our analysis also reveals connections of Ch-BE to generalized Calogero Sutherland Hamiltonian (CSH) and Wishart ensembles. This along with already known connections of complex systems without chirality to CSH strongly hints the later to be the "backbone" Hamiltonian governing the spectral dynamics of Complex systems.
