Quasi-Normal Modes of a Schwarzschild White Hole
Nigel T. Bishop, Amos S. Kubeka
We investigate perturbations of the Schwarzschild geometry using a linearization of the Einstein vacuum equations within a Bondi-Sachs, or null cone, formalism. We develop a numeri…
Strategies for the Characteristic Extraction of Gravitational Waveforms
M. C. Babiuc, N. T. Bishop, B. Szilagyi +1
We develop, test and compare new numerical and geometrical methods for improving the accuracy of extracting waveforms using characteristic evolution. The new numerical method invol…
Origin and control of high-temperature ferromagnetism in semiconductors
Shinji Kuroda, Nozomi Nishizawa, Koki Takita +4
The extensive experimental and computational search for multifunctional materials has resulted in the development of semiconductor and oxide systems, such as (Ga,Mn)N, (Zn,Cr)Te, a…
Three-body resonances Lambda-n-n and Lambda-Lambda-n
V. B. Belyaev, S. A. Rakityansky, W. Sandhas
Possible bound and resonant states of the hypernuclear systems and are sought as zeros of the corresponding three-body Jost functions calculated within the framework of…
Universality and programmability of quantum computers
Willem Fouche', Johannes Heidema, Glyn Jones +1
Manin, Feynman, and Deutsch have viewed quantum computing as a kind of universal physical simulation procedure. Much of the writing about quantum logic circuits and quantum Turing…
The Fermat-Torricelli problem in normed planes and spaces
Horst Martini, Konrad J Swanepoel, Gunter Weiss
We investigate the Fermat-Torricelli problem in d-dimensional real normed spaces or Minkowski spaces, mainly for d=2. Our approach is to study the Fermat-Torricelli locus in a geom…
