Wei-Norman equations for classical groups
Szymon Charzyński, Marek Kuś
We show that the non-linear autonomus Wei-Norman equations, expressing the solution of a linear system of non-autonomous equations on a Lie algebra, can be reduced to the hierarchy…
Fraction of isospectral states exhibiting quantum correlations
Michał Oszmaniec, Marek Kuś
For several types of correlations: mixed-state entanglement in systems of distinguishable particles, particle entanglement in systems of indistinguishable bosons and fermions and n…
Convex bodies of states and maps
Janusz Grabowski, Alberto Ibort, Marek Kuś +1
We give a general solution to the question when the convex hulls of orbits of quantum states on a finite-dimensional Hilbert space under unitary actions of a compact group have a n…
A universal framework for entanglement detection
Michał Oszmaniec, Marek Kuś
We construct nonlinear multiparty entanglement measures for distinguishable particles, bosons and fermions. In each case properties of an entanglement measures are related to the d…
Wei-Norman equations for a unitary evolution
Szymon Charzyński, Marek Kuś
The Wei-Norman technique allows to express the solution of a system of linear non-autonomous differential equations in terms of product of exponentials. In particular it enables to…
