Photonic band structures of periodic arrays of pores in a metallic host: tight-binding beyond the quasistatic approximation
Kwangmoo Kim, D. Stroud
We have calculated the photonic band structures of metallic inverse opals and of periodic linear chains of spherical pores in a metallic host, below a plasma frequency $ω_{\text{p}…
Magnonic Crystal with Two-Dimensional Periodicity as a Waveguide for Spin Waves
Rakesh P. Tiwari, D. Stroud
We describe a simple method of including dissipation in the spin wave band structure of a periodic ferromagnetic composite, by solving the Landau-Lifshitz equation for the magnetiz…
Tunable Band Gap in Graphene with a Non-Centrosymmetric Superlattice Potential
Rakesh P Tiwari, D. Stroud
We show that, if graphene is subjected to the potential from an external superlattice, a band gap develops at the Dirac point provided the superlattice potential has broken inversi…
Model for the magnetoresistance and Hall coefficient of inhomogeneous graphene
Rakesh P. Tiwari, D. Stroud
We show that when bulk graphene breaks into n-type and p-type puddles, the in-plane resistivity becomes strongly field dependent in the presence of a perpendicular magnetic field,…
Scaling Properties of Random Walks on Small-World Networks
E. Almaas, R. V. Kulkarni, D. Stroud
Using both numerical simulations and scaling arguments, we study the behavior of a random walker on a one-dimensional small-world network. For the properties we study, we find that…
Theory of Two-Dimensional Josephson Arrays in a Resonant Cavity
E. Almaas, D. Stroud
We consider the dynamics of a two-dimensional array of underdamped Josephson junctions placed in a single-mode resonant cavity. Starting from a well-defined model Hamiltonian, whic…
