Flat lens without optical axis: Theory of imaging
W. T. Lu, S. Sridhar
We derive a general theory for imaging by a flat lens without optical axis. We show that the condition for imaging requires a material having elliptic dispersion relations with neg…
Close-packed dimers on nonorientable surfaces
Wentao T. Lu, F. Y. Wu
The problem of enumerating dimers on an M x N net embedded on non-orientable surfaces is considered. We solve both the Moebius strip and Klein bottle problems for all M and N with…
Quantum correlations and classical resonances in an open chaotic system
Wentao T. Lu, Kristi Pance, Prabhakar Pradhan +1
We show that the autocorrelation of quantum spectra of an open chaotic system is well described by the classical Ruelle-Pollicott resonances of the associated chaotic strange repel…
Density of the Fisher zeroes for the Ising model
Wentao T. Lu, F. Y. Wu
The density of the Fisher zeroes, or zeroes of the partition function in the complex temperature plane, is determined for the Ising model in zero field as well as in a pure imagina…
Quantum resonances and decay of a chaotic fractal repeller observed using microwaves
Wentao Lu, M. Rose, K. Pance +1
The quantum resonances of classically chaotic n-disk geometries were studied experimentally utilizing thin 2-D microwave geometries. The experiments yield the frequencies and width…
Partition function zeroes of a self-dual Ising model
Wentao T. Lu, F. Y. Wu
We consider the Ising model on an rectangular lattice with an asymmetric self-dual boundary condition, and derive a closed-form expression for its partition function. W…
