Correlations in interacting electron liquids: Many-body statistics and hyperuniformity
收藏 引用
Physical Review B 2024年 第10期110卷 104201页
作者: Haina Wang Rhine Samajdar Salvatore Torquato Department of Chemistry Department of Physics Princeton Center for Theoretical Science Princeton Materials Institute Program in Applied and Computational Mathematics
Disordered hyperuniform many-body systems are exotic states of matter with novel optical, transport, and mechanical properties. These systems are characterized by an anomalous suppression of large-scale density fluctu... 详细信息

Nonlinear Analysis, Theory, Methods and Applications 2023年 第1期232卷
作者: López-Gómez, Julián Sampedro, Juan Carlos Institute of Interdisciplinary Mathematics Department of Mathematical Analysis and Applied Mathematics Complutense University of Madrid Madrid28040 Spain
In this paper, we ascertain the global λ-structure of the set of positive and negative solutions bifurcating from u=0 for the semilinear elliptic BVP −dΔu=λ〈a,∇u〉+u+λu2−uqinΩ,u=0on∂Ω,according to the values of d... 详细信息

arXiv 2025年
作者: Chung, Jui-Hui Shapiro, Jacob Program in Applied and Computational Mathematics Princeton University United States Department of Mathematics Princeton University United States
Let R be a unitary operator whose spectrum is the circle. We show that the set of unitaries U which essentially commute with R (i.e., [U, R] ≡ UR − RU is compact) is path-connected. Moreover, we also calculate the se...

arXiv 2024年
作者: Ghrist, Robert Gould, Julian Lopez, Miguel Department of Mathematics Department of Electrical & Systems Engineering and Program in Applied Mathematics & Computational Science University of Pennsylvania United States
This note reformulates certain classical combinatorial duality theorems in the context of order lattices. For source-target networks, we generalize bottleneck path-cut and flow-cut duality results to edges with capaci... 详细信息
