Homotopy Actions, Cyclic Maps and their Duals
Martin Arkowitz, Gregory Lupton
An action of A on X is a map F: AxX to X such that F|_X = id: X to X. The restriction F|_A: A to X of an action is called a cyclic map. Special cases of these notions include group…
Dynamics of a nanomechanical resonator coupled to a superconducting single-electron transistor
M. P. Blencowe, J. Imbers, A. D. Armour
We present an analysis of the dynamics of a nanomechanical resonator coupled to a superconducting single electron transistor (SSET) in the vicinity of the Josephson quasiparticle (…
Domination Cover Pebbling: Graph Families
James Gardner, Anant P. Godbole, Alberto Mokak Teguia +3
Given a configuration of pebbles on the vertices of a connected graph G, a pebbling move is defined as the removal of two pebbles from some vertex, and the placement of one of thes…
Creation of Stable Multipartite Entangled States in Spin Chains with Defects
L. F. Santos
We show how defects in a spin chain described by the XXZ model may be used to generate entangled states, such as Bell and W states, and how to maintain them with high fidelity. In…
Extension problems for representations of crossed-product C*-algebras
Astrid an Huef, S. Kaliszewski, Iain Raeburn +1
We consider the following problem. Suppose is an action of a locally compact group on a -algebra , is a closed subgroup of , and is a covariant repre…
