Intermittent emission of particles from a Bose-Einstein condensate in a one-dimensional lattice
L. Q. Lai, Z. Li, Q. H. Liu +1
We investigate particle emission from a Bose-Einstein condensate with periodically modulated interactions in a one-dimensional lattice. Within perturbative analysis, which leads to…
Quantifying human mixing patterns in Chinese provinces outside Hubei after the 2020 lockdown was lifted
Yining Zhao, Samantha ODell, Xiaohan Yang +7
Contact patterns play a key role in the spread of respiratory infectious diseases in human populations. During the COVID-19 pandemic the regular contact patterns of the population…
Inferring high-resolution human mixing patterns for disease modeling
Dina Mistry, Maria Litvinova, Ana Pastore y Piontti +12
Mathematical and computational modeling approaches are increasingly used as quantitative tools in the analysis and forecasting of infectious disease epidemics. The growing need for…
Coevolution spreading in complex networks
Wei Wang, Quan-Hui Liu, Junhao Liang +2
The propagations of diseases, behaviors and information in real systems are rarely independent of each other, but they are coevolving with strong interactions. To uncover the dynam…
Epidemic spreading on time-varying multiplex networks
Quan-Hui Liu, Xinyue Xiong, Qian Zhang +1
Social interactions are stratified in multiple contexts and are subject to complex temporal dynamics. The systematic study of these two features of social systems has started only…
Impacts of Opinion Leaders on Social Contagions
Quan-Hui Liu, Feng-Mao Lü, Qian Zhang +2
Opinion leaders are ubiquitous in both online and offline social networks, but the impacts of opinion leaders on social behavior contagions are still not fully understood, especial…
Synergistic interactions promote behavior spreading and alter phase transition on multiplex networks
Quan-Hui Liu, Wei Wang, Shi-Min Cai +2
Synergistic interactions are ubiquitous in the real world. Recent studies have revealed that, for a single-layer network, synergy can enhance spreading and even induce an explosive…
Explosive spreading on complex networks: the role of synergy
Quan-Hui Liu, Wei Wang, Ming Tang +2
In spite of the vast literature on spreading dynamics on complex networks, the role of local synergy, i.e., the interaction of elements that when combined produce a total effect gr…
Suppressing disease spreading by using information diffusion on multiplex networks
Wei Wang, Quan-Hui Liu, Shi-Min Cai +3
Although there is always an interplay between the dynamics of information diffusion and disease spreading, the empirical research on the systemic coevolution mechanisms connecting…
Predicting the epidemic threshold of the susceptible-infected-recovered model
Wei Wang, Quan-Hui Liu, Lin-Feng Zhong +3
Researchers have developed several theoretical methods for predicting epidemic thresholds, including the mean-field like (MFL) method, the quenched mean-field (QMF) method, and the…
Impacts of complex behavioral responses on asymmetric interacting spreading dynamics in multiplex networks
Quan-Hui Liu, Wei Wang, Ming Tang +1
Information diffusion and disease spreading in communication-contact layered network are typically asymmetrically coupled with each other, in which how an individual being aware of…
Distribution of xp in some molecular rotational states
Q. H. Liu
Developing the analysis of the distribution of the so-called posmom xp to the spherical harmonics that represents some molecular rotational states for such as diatomic molecules an…
Geometric momentum in the Monge parametrization of two dimensional sphere
D. M. Xun, Q. H. Liu
A two dimensional surface can be considered as three dimensional shell whose thickness is negligible in comparison with the dimension of the whole system. The quantum mechanics on…
Geometric Momentum: the Proper Momentum for a Free Particle on a Two-dimensional Sphere
Q. H. Liu, L. H. Tang, D. M. Xun
In Dirac's canonical quantization theory on systems with second-class constraints, the commutators between the position, momentum and Hamiltonian form a set of algebraic relations…
Raising and lowering operators for angular momentum quantum numbers l in spherical harmonics
Q. H. Liu, D. M. Xun, L. Shan
Two vector operators aimed at shifting angular momentum quantum number l in spherical harmonics |lm>, primarily proposed by Prof. X. L. Ka in 2001, are further studied. For a given…
