The Bloch-vector space for N-level systems -- the spherical-coordinate point of view
Gen Kimura, Andrzej Kossakowski
Bloch-vector spaces for -level systems are investigated from the spherical-coordinate point of view in order to understand their geometrical aspects. We show that the maximum ra…
A Description of Quantum Chaos
Kei Inoue, Andrzej Kossakowski, Masanori Ohya
A measure describing the chaos of a dynamics was introduced by two complexities in information dynamics, and it is called the chaos degree. In particular, the entropic chaos degree…
How Can We Observe and Describe Chaos?
Andrzej Kossakowski, Masanori Ohya, Yosio Togawa
We propose a new approach to define chaos in dynamical systems from the point of view of Information Dynamics. Observation of chaos in reality depends upon how to observe it, for i…
A Class of Linear Positive Maps in Matrix Algebras
Andrzej Kossakowski
A class of linear positive, trace preserving maps in is given in terms of affine maps in $\bBR^{n^2-1}$ which map the closed unit ball into itself.
