Large Photonic Band Gaps in Certain Periodic and Quasi-Periodic Networks in two and three dimensions
S. K. Cheung, T. L. Chan, Z. Q. Zhang +1
The photonic band structures in certain two- and three-dimensional periodic networks made of one-dimensional waveguides are studied by using the Floquet-Bloch theorem. We find that…
Numerical study of metastability due to tunneling: The quantum string method
Tiezheng Qian, Weiqing Ren, Jing Shi +2
We generalize the string method, originally designed for the study of thermally activated rare events, to the calculation of quantum tunneling rates. This generalization is based o…
Coupling of Magnetic Order, Ferroelectricity, and Lattice Strain in Multiferroic Rare Earth Manganites
B. Lorenz, C. R. dela Cruz, F. Yen +3
Multiferroic rare earth manganites attracted recent attention because of the coexistence of different types of magnetic and ferroelectric orders resulting in complex phase diagrams…
Effect of the radiative background flux in convection
A. Brandenburg, K. L. Chan, A. Nordlund +1
Numerical simulations of turbulent stratified convection are used to study models with approximately the same convective flux, but different radiative fluxes. As the radiative flux…
Charge carrier correlation in the electron-doped t-J model
P. W. Leung
We study the t-t'-t''-J model with parameters chosen to model an electron-doped high temperature superconductor. The model with one, two and four charge carriers is solved on a 32-…
First-principles effective-mass Hamiltonian for semiconductor nanostructures in a magnetic field
Bradley A. Foreman
A multi-band effective-mass Hamiltonian is derived for lattice-matched semiconductor nanostructures in a slowly varying external magnetic field. The theory is derived from the firs…
