Ionization and excitation of low-lying circular states of the hydrogen atom in strong circularly polarized laser fields
Jarosław H. Bauer, Zbigniew Walczak
We perform ab initio calculations for the hydrogen atom initially in one of the six circular bound states with the principal quantum numbers n = 2, 3 and 4, irradiated by a short c…
Dominance of quantum over classical correlations: entropic and geometric approach
Zbigniew Walczak, Iwona Wintrowicz, Katarzyna Zakrzewska
Recently, it has been shown that there exist quantum states for which quantum correlations dominate over classical correlations. Inspired by this observation, we investigate the pr…
On two-qubit states ordering with quantum discords
Małgorzata Okrasa, Zbigniew Walczak
The counterintuitive effect of non-unique ordering of two-qubit states with quantum entanglement measures was discovered over ten years ago. More precisely, it was shown by Monte C…
Total correlations and mutual information
Zbigniew Walczak
In quantum information theory it is generally accepted that quantum mutual information is an information-theoretic measure of total correlations of a bipartite quantum state. We ar…
Unstable particles as open quantum systems
P. Caban, J. Rembielinski, K. A. Smolinski +1
We present the probability preserving description of the decaying particle within the framework of quantum mechanics of open systems taking into account the superselection rule pro…
Entanglement and Tensor Product Decomposition for Two Fermions
Pawel Caban, Krzysztof Podlaski, Jakub Rembielinski +2
The problem of the choice of tensor product decomposition in a system of two fermions with the help of Bogoliubov transformations of creation and annihilation operators is discusse…
