Distinctive subdynamic features of bipartite systems
A. K. Rajagopal, A. R. Usha Devi, R. W. Rendell +1
There are several important bipartite systems of great interest in condensed matter physics and in quantum information science. In condensed matter systems, the subsystems are exam…
Distinctive features in the quantum sub-dynamics of bipartite systems
A. K. Rajagopal, A. R. Usha Devi, R. W. Rendell +1
Distinctive features in the sub-dynamics of an interacting bipartite system are explored. The sub-dynamic Heisenberg operators are introduced in a novel way leading to the quasi-pa…
Entanglement in particle-detector interactions
Michael Steiner, R. W. Rendell
It is predicted by Schrodinger's equation that entanglement will occur in the interaction between detector and particle. We provide an analysis of the entanglement using the Gurvit…
Geometry and Product States
Robert B. Lockhart, Michael J. Steiner, Karl Gerlach
As separable states are a convex combination of product states, the geometry of the manifold of product states is studied. Prior results by Sanpera, Vidal and Tarrach are extended.…
