Statistical Properties of Correlated Semiclassical Bands in Tight-Binding Small-World Networks
EntropyLinear tight-binding models with long-range interactions and small-world geometry have a broad energy spectrum in the nearest neighbor coupling limit, while the spectrum becomes narrow in the fully connected limit due to the emergence of flat bands.

CrystalsFor the first time, we explored the optical, electronic, mechanical, and structural properties of the Ruddlesden–Popper phase family member X2CaTa2O7 (X = Li, Na, K, and Rb) by using density functional theory (DFT) with the Perdew–Burke–Ernzerhof (PBE ...

Winding Number, Density of States, and Acceleration
International Mathematics Research NoticesAbstractWinding number and density of states are two fundamental physical quantities for non-self-adjoint quasi-periodic Schrödinger operators, which reflect the asymptotic distribution of zeros of the characteristic determinants of the truncated operators under Dirichlet boundary condition, with respect to complexified phase and the energy ...

Exploring network structure with the density of states
Physica A: Statistical Mechanics and its ApplicationsCommunity detection, as well as the identification of other structures like core periphery and disassortative patterns, is an important topic in network analysis. While most methods seek to find the best partition of the network according to some criteria, there is a body of results that suggest that a single network can have many good but distinct ...
