Quantum billiards and constrained random wave correlations

W. E. Bies, N. Lepore, E. J. Heller

We study chaotic eigenfunctions in wedge-shaped and rectangular regions using a generalization of Berry's conjecture. An expression for the two-point correlation function is derive…

The thermal conductivity reduction in HgTe/CdTe superlattices

W. E. Bies, H. Ehrenreich, E. Runge

The techniques used previously to calculate the three-fold thermal conductivity reduction due to phonon dispersion in GaAs/AlAs superlattices (SLs) are applied to HgTe/CdTe SLs. Th…

Scarring Effects on Tunneling in Chaotic Double-Well Potentials

W. E. Bies, L. Kaplan, E. J. Heller

The connection between scarring and tunneling in chaotic double-well potentials is studied in detail through the distribution of level splittings. The mean level splitting is found…

Phonon Dispersion Effects and the Thermal Conductivity Reduction in GaAs/AlAs Superlattices

W. E. Bies, R. J. Radtke, H. Ehrenreich

The experimentally observed order-of-magnitude reduction in the thermal conductivity along the growth axis of (GaAs)_n/(AlAs)_n (or n x n) superlattices is investigated theoretical…

Localization of Eigenfunctions in the Stadium Billiard

W. E. Bies, L. Kaplan, M. R. Haggerty +1

We present a systematic survey of scarring and symmetry effects in the stadium billiard. The localization of individual eigenfunctions in Husimi phase space is studied first, and i…

Thermoelectric Properties of Anisotropic Systems

W. E. Bies, R. J. Radtke, H. Ehrenreich

The effective transport coefficients and figure of merit ZT for anisotropic systems are derived from a macroscopic formalism. The full tensorial structure of the transport coeffici…
