We explore the connections between dissipative quantum phase transitions and non-Hermitian random matrix theory. For this, we work in framework of Dicke model which is archetypal symmetry-breaking open systems. establish that Liouvillian describing dynamics exhibits distinct spectral features integrable chaotic character on two sides critical point. follow distribution spacings complex eigenvalues across In normal superradiant phases, distributions are two-dimensional Poisson Ginibre unitary...
Abstract We study non-local measures of spectral correlations and their utility in characterizing distinguishing between the distinct eigenstate phases quantum chaotic many-body localized systems. focus on two related quantities, form factor density all gaps, show that they furnish unique signatures can be used to sharply identify phases. demonstrate this by numerically studying three one-dimensional spin chain models with (i) quenched disorder, (ii) periodic drive (Floquet), (iii)...
Chaos sets a fundamental limit to quantum-information processing schemes. We study the onset of chaos in spatially extended quantum many-body systems that are relevant optical devices. consider an version Tavis-Cummings model on finite chain. By studying level-spacing statistics, adjacent gap ratios, and spectral form factors, we observe transition from integrability as hopping between sites is increased above value. The results obtained by means exact numerical diagonalization which becomes...
Abstract The essential oil profiles of peel and leaf oils a new Citrus hybrid its parents, the triploid seedless lime diploid Kagzi lime, were established after resolving using capillary GC. chemical composition was discussed in comparison with that parents. analytical properties found to be influenced by both rich organoleptically important neral geranial.
