Stability of periodic traveling waves for complex modified Korteweg-de Vries equation
Sevdzhan Hakkaev, Iliya D. Iliev, Kiril Kirchev
We study the existence and stability of periodic traveling-wave solutions for complex modified Korteweg-de Vries equation. We also discuss the problem of uniform continuity of the…
Centralizers in endomorphism rings
Vesselin Drensky, Jeno Szigeti, Leon van Wyk
We prove that the centralizer Cen(f) in Hom_R(M,M) of a nilpotent endomorphism f of a finitely generated semisimple left R-module M (over an arbitrary ring R) is the homomorphic im…
Design of quantum Fourier transforms and quantum algorithms by using circulant Hamiltonians
B. T. Torosov, N. V. Vitanov
We propose a technique for design of quantum Fourier transforms, and ensuing quantum algorithms, in a single interaction step by engineered Hamiltonians of circulant symmetry. The…
Simple implementation of a quantum search with trapped ions
Svetoslav S. Ivanov, Peter A. Ivanov, Nikolay V. Vitanov
We propose an ion trap implementation of Grover's quantum search algorithm for an unstructured database of arbitrary length N. The experimental implementation is appealingly simple…
Degenerate Landau-Zener model: Exact analytical solution
G. S. Vasilev, S. S. Ivanov, N. V. Vitanov
The exact analytical solution of the degenerate Landau-Zener model, wherein two bands of degenerate energies cross in time, is presented. The solution is derived by using the Morri…
Polymer Chain Adsorption on a Solid Surface: Scaling Arguments and Computer Simulations
A. Milchev, V. Rostiashvili, S. Bhattacharya +1
We examine the phase transition of polymer adsorption as well as the underlying kinetics of polymer binding from dilute solutions on a structureless solid surface. The emphasis is…
